Description
Every footprint trader has seen it: a huge volume prints at the low, someone calls it absorption, and price sails straight through it. A big number alone is not absorption. Absorption is effort that failed: aggressive traders hit one side of the book, passive liquidity accepts that pressure, and price cannot continue. The proof is not the volume alone. The proof is the rejection.
OFS ConfirmedAbsorption examines every real tick level of a closed footprint candle and finds the prices where aggressive pressure ran into passive liquidity and stalled. Wicks Only is the default because reversal absorption normally belongs at the extreme; Body Only and All remain available for research. A qualified print is still only a candidate. It becomes a confirmed level only when the candle closes away from the entire zone by the configured distance. No confirming close means no historical line.
Each confirmed tick is drawn as one horizontal line at one fixed price. The price never moves. While the market is far away the line stays short; as price approaches, it extends smoothly towards the current bar. The first return freezes the visible line at the touch bar, while the level underneath continues through its documented lifecycle. A touch followed by a reaction away from the level makes it USED, and it fades a little more after every further use. Repeated tests are tracked until the level is used up. A close through the zone marks it BROKEN; broken levels remain briefly visible for the selected number of bars. Old levels expire by session age. A small one-line control panel changes Ratio in steps of 100, shows or hides the absorptions and extends the untouched long or short levels to the current bar with one click. The first scan when a chart opens and every change of a setting are built in the background, so the chart never freezes, and the lines follow every tick behind the candles. The lines can end before the right edge of the chart (Line Right Offset) to keep the Depth Of Market free.
Closed-bar detections never repaint. The optional live preview is clearly dotted and faint, uses the same RTH or ETH filter as the closed calculation and never changes historical diagnostics. Missing footprint data is not treated as an empty signal: the chart reports INSUFFICIENT DATA with the reason instead of silently pretending that no absorption exists - even while the panel is hidden.
Hybrid volume mode lets the volume minimum adapt to your instrument by itself, learned from the closed bars of the last sessions - separately for regular and extended hours, with configurable regular hours in New York time. The adaptive minimum is the same after a restart or a recalculation.
The diagnostics panel explains why candidates were rejected and shows how often each lifecycle step happened on your chart: touches, reactions, timeouts, rearms, breaks and expiries. A licensed one-click CSV export writes the current levels with their history for calibration on your own data. Platform alerts and Telegram can report activation, touch, successful use and break events. Everything is off by default, historical events are never replayed as live notifications, and Telegram delivery cannot block the calculation.
The same protected DLL is built for classic ATAS and ATAS X on the current .NET 10 runtime. The pure detection engine is covered by automated tests derived from the written technical specification and by a replay over real one-minute footprint data that checks every lifecycle branch and proves that the live path and a plain recalculation produce identical levels bar by bar.
Installation guide
1. Create or sign in to your OrderFlowSmith account with the same e-mail address used by your ATAS account. When access to OFS ConfirmedAbsorption is activated and the e-mails match, ATAS delivers the indicator automatically; do not install a DLL manually.
2. Open or fully restart ATAS so the automatically delivered indicator becomes available in the indicator catalogue. Whenever an update is released through ATAS, fully restart the platform; ATAS downloads and loads the new version automatically.
3. If your ATAS account uses a different e-mail address than your OrderFlowSmith account, write to us at orderflowsmith.com/contact - we move the license to your ATAS e-mail and ATAS delivers the indicator automatically.
4. Open a chart and add OFS ConfirmedAbsorption from the OrderFlowSmith group.
5. Paste your OFS license key into 01 - License. The key is verified locally.
6. Make sure the feed provides Bid/Ask footprint volume. If it does not, the chart shows INSUFFICIENT DATA with the reason; if the loaded history is too short, the notice says how many sessions are covered.
7. If your instrument has other regular hours than 09:30-16:00 New York, set RTH Start and RTH End in 05 - Session and Time.
8. Start with the defaults and calibrate Ratio, Stacked Levels, Minimum Volume, Confirm Close Distance and Max Age on your own data using the CSV export in 15 - Log.

Changelog — version 1.4.8
1.4.8 - NOTICES OFF BY DEFAULT AND BELOW EACH OTHER; A DOT ON THE HIDDEN BUTTON.
- The waiting and error notices are off by default, also on saved charts - switch them on with Show Notices. A missing or invalid licence is always shown.
- Notices start 50 px from the top, below the row of hidden panel buttons (Notice Offset Y), and the notices of several OFS indicators stack below each other by themselves - they never cover a control panel or a hidden panel button.
- The hidden panel button shows a dot before the name: green when anything on the control panel is switched on, an empty grey ring when everything is off - you see at once which indicator draws on the chart.
1.4.7 - THE TIME ZONE ROW SWITCHES TO MANUAL AT ONCE.
- A non-zero Manual Offset (hours) switches Time Zone to Manual. Until now the settings window kept showing the previous zone until it was reopened - now the Time Zone row shows Manual at once.
- Nothing else changes.
1.4.6 - LOG: ONE SWITCH, ITS OWN FOLDER.
- New in 15 · Log: Log (on / off, off by default) and Log Folder. Switched on, the indicator writes everything it does into its own log - its settings and every change of them, the chart, the calculation, the scan of the session window and every rebuild with its duration, every new level and every change of its state, its alerts and errors and what the panel shows. Keys, tokens and IDs are never written.
- The files go into the folder of the indicator inside Log Folder, for example D:\logs\OFS ConfirmedAbsorption - one file per chart and day, with the computer and the platform in the file name.
- Log Folder is now the folder of the log. Export CSV Now writes into the same folder of the indicator (until 1.4.5 into a subfolder named after the computer); Enable Diagnostics and Export CSV Now stay below Log Folder.
1.4.5 - SAVED CHARTS KEEP THEIR RTH HOURS ACROSS THE CLOCK CHANGE.
- A chart saved before this update with RTH Start / RTH End at the default now always loads as 09:30 - 16:00 New York, also when it was saved in summer and opened in winter (or the other way round). Until now the one-time conversion of the old saved value used today's clock offset, so such a chart could start one hour off. Hours you set yourself convert as before.
1.4.4 - RTH HOURS KEEP THEIR TIME AFTER A CLOCK CHANGE.
- RTH Start / RTH End are shown and entered in your Time Zone as before, but the chart now saves them in New York exchange time. Until 1.4.3 a chart saved before a daylight-saving change opened with the regular hours one hour off - for example with Time Zone = Bratislava in the week when Europe and the US change clocks on different dates. A saved chart is converted once on its first load; after that the chart saves New York time and opens with the same hours in summer and winter.
1.4.3 - LEVELS ON 1-HOUR, 4-HOUR AND DAILY CHARTS TOO.
- The window of the first scan and the lifetime of a level are counted in sessions (5 by default). On a daily chart that was 5 candles and almost no level appeared. A session now counts at least 40 candles: on 1-hour, 4-hour and daily charts neighbouring sessions are joined (daily: 40 days per session). 1-minute to 30-minute charts are unchanged.
- The information panel and the notices no longer hide behind an open control panel: where the control panel covered them (top right on a narrower chart), they now sit just below it. Without overlap nothing moves.
1.4.2 - CONTROL PANELS AND HIDDEN BUTTONS LINE UP BY THEMSELVES; EVERYTHING OFF BY DEFAULT.
- The buttons of hidden control panels of all OFS indicators on a chart line up side by side by themselves at the top centre, in the order of the chart's indicator list; open control panels at the same place stack below each other. A different position or offset in the settings keeps a button or panel in its own place.
- New default places, also on saved charts: Control Panel Position Top Center, Offset X 0, Offset Y 40; Hidden Button Position Top Center, Offset X 0, Offset Y 5.
- Every function of the control panel is off by default for a newly added indicator (ON / OFF - Show Absorptions - and the LONG / SHORT line extensions), so a new chart shows nothing until you switch it on. A saved chart keeps its own switches.
1.4.1 - DIAGNOSTICS SHOW WHAT HAPPENED ON THE CHART.
- Enable Diagnostics (15 · Log) lists the confirmed and merged levels and how often each lifecycle step happened (touches, reactions, timeouts, rearms, breaks, expiries); the counts of discarded candidates are no longer shown.
1.4.0 - THE CHART OPENS WITHOUT WAITING; LINES CAN END BEFORE THE RIGHT EDGE.
- Opening a chart no longer waits for the footprint scan of the last sessions: it is built in the background, the same way a changed setting is rebuilt, and the levels appear as soon as it is ready - the same levels as before. Meanwhile the notice (or the panel) says SCANNING. Bars that close during the scan are included.
- New: Line Right Offset (px) in 10 · Visual - the absorption lines, their touch points and strength numbers end this many pixels before the right edge of the chart, so they leave free what you keep there (for example the Depth Of Market). 0 = up to the edge (default).
- Drawing never waits for the calculation: while a bar is being processed, the last finished picture is shown.
- The red outage frame returns to normal after 4 s of healthy data (10 s after lost data or a lost connection) instead of 30 s.
1.3.3 - RED PANEL FRAME WHEN THE CONNECTION OR THE DATA DROPS; LOG FOLDER.
- New: the indicator watches the connection and the market data - the account connection (for example Rithmic) lost for more than 15 s, no market data for 15 s while CME is trading, or the data more than 5 s late. While that lasts, the control panel and the hidden panel button get a thick red frame; everything keeps working, and the frame returns to normal after 30 s of healthy data. No alert and no sound. Setting Control Panel Outage Frame (on by default) in the control panel group.
- New: Log Folder (in the Log group) - the folder for the files written by Export CSV Now, for example D:\logs; the files go into a subfolder named after the computer, so two computers can share one synchronised folder. Empty = the OrderFlowSmith folder in AppData as until now.
1.3.2 - THE CONTROL PANEL ZOOMS TO FIT A NARROW CHART.
- On a chart narrower than the control panel (a smaller monitor, several charts side by side) the whole panel now shrinks evenly - the same buttons in the same places, only smaller, down to font size 6 - instead of running out of the chart or over its own name. It grows back when the chart is wide again and does not jump back and forth near the limit. New setting Control Panel Zoom To Fit (on by default).
1.3.1 - ALERTS: SOUND ONLY, NO POPUP WINDOW.
- When an alert fires, the indicator only plays its sound - no popup window appears on the chart.
1.3.0 - HIDE THE CONTROL PANEL; THE NEW-VERSION CARD POINTS TO ATAS; A SHORTER SETTINGS LIST.
- HIDE next to the panel name hides the control panel: only a small button with the product name (ConfirmedAbsorption) stays on the chart - click it and the panel is back. Hiding changes nothing else: everything switched on keeps working.
- New settings in 12 · Control Panel: Hide Control Panel, Hidden Button Position, Hidden Button Offset X / Y (px), Hidden Button Font Size, Hidden Button Text Color and Hidden Button Background - by default the button sits where the panel sits.
- The new-version card now says that ATAS delivers the new version to your platform automatically (until 1.2.7 it pointed to a download in your account on orderflowsmith.com, which is no longer offered).
- The settings list shows what is yours to tune: the engine internals of the detection and the lifecycle are no longer listed and keep their proven values. Saved charts keep every value.
- 06 · Detection: the choice for prices without volume on the other side is now called Empty Opposite Side - the saved value stays.
- The notice about a short history no longer points to a setting: load more days of history into the chart.
- Setting descriptions and the manual say what each setting changes on the chart.
1.2.7 - PRODUCT NAME IN TELEGRAM, READABLE ALERTS, "AND" INSTEAD OF "&" IN SETTINGS.
- Telegram messages start with the product name [OFS ConfirmedAbsorption] instead of a short internal code.
- The ATAS alert window shows the readable message first, then the machine-readable details with the product name instead of a short code.
- Settings group 05 · Session and Time is written with "and": ATAS X showed the "&" sign doubled (for example "Session && Time") and the classic ATAS hid it.
- Only names changed. Saved settings and chart templates keep all their values.
1.2.6 - ABSORPTION LINES CAN BE EXTENDED TO THE RIGHT.
New Extend Lines Right (px), default 0 = as before: every live absorption level - one price has not come back to yet - is extended to the right by this many pixels beyond its normal end. A fresh absorption at the live candle used to have an almost zero-length line hidden under the candle, so only its strength number was visible; with a few dozen pixels it now shows next to the candle. Levels price already came back to keep ending where they were touched. The provisional run that already confirms on the live bar (Realtime Sequence) is extended the same way. Setting in 10 - Visual.
1.2.5 - THE NEW-VERSION CARD HAS ONLY THE CLOSE BUTTON.
The card announcing a new version no longer has a cross in its top corner - the Close button at the bottom is the only way to close it, the same in every OFS indicator. Closing it still remembers that version, so the card does not come back until the next release. Nothing else changed.
1.2.4 - DRAW ABOVE CANDLES IN THE WHOLE FAMILY; NOTHING OVER THE PANELS OF OTHER INDICATORS.
New setting Draw Above Candles (10 · Visual), off by default: the absorption levels and candidates sit behind the candles; on puts it above the candles. ATAS applies this order to the whole price panel - while ANY indicator on the panel has it on, everything on the panel is drawn above the candles - so the whole OFS family now has the same switch with the same default. Whatever the setting, nothing ConfirmedAbsorption draws on the chart covers the panels and windows of other indicators; only its own panel stays on top.
Fixed: while the price panel is drawn above the candles (this or any other indicator with the switch on) and the chart is scrolled back so that the last bar is off screen, ATAS does not draw the live chart layer at all - the absorption levels and candidates disappeared until the last bar was back in view. In that case the content now goes to the main chart layer, so it is always there.
1.2.3 - CHECK FOR UPDATES CHECKS AT ONCE; THE NEW-VERSION CARD ALWAYS IN THE MIDDLE OF THE CHART.
Unticking Check For Updates in the settings and ticking it again now asks orderflowsmith.com for the latest version straight away and, when a newer version exists, shows the card at once - also on a weekend or in a quiet market with no new ticks. Until now the check started only if the chart happened to redraw between the two clicks, so without ticks nothing happened, and the answer waited for the next redraw. Ticking it again also brings back a card you closed earlier.
The new-version card always opens in the middle of the chart, whatever the position of the control panel or the notices of the indicator. Nothing else changed: the calculation, the settings and saved charts stay as they were.
1.2.2 - CONTROL PANEL ON THE COMMON OFS TEMPLATE.
The one-line control panel is now drawn by the same code as every OFS control panel: Ratio % is a framed card "Ratio % - 300 +", ON / LONG / SHORT are blue when on and grey when off, - and + flash blue on a click - the same look as Entry Desk, AbsorbEntry, FiboLevels and the strategies. It sits exactly in the top centre (offset X 0; it used to be 20 px right of centre), so the FiboLevels control panel fits right under it.
1.2.1 - SETTINGS IN THE COMMON OFS ORDER; CHECK FOR UPDATES ON DEMAND.
The settings window follows the same layout in every OFS indicator: 01 License first (product, key, website, version, Check For Updates), then Session and Time where it applies, the indicator's own groups, and at the end Panel, Alerts, Telegram and Log. Saved charts keep all their values - only names and the order of the groups changed.
Check For Updates now also works on demand: untick it and tick it again and the indicator asks orderflowsmith.com straight away - a new-version card you closed earlier comes back as well. Until now the switch promised this but the check waited for its daily turn.
The strength percentage in the middle of every absorption line now sits on a dark box (Strength Background, default black - transparency is part of the colour, fully transparent = no box), so the line running behind it no longer makes the number hard to read. The same as in OFS Entry Desk.
05 - Session and Time gains Time Zone and Manual Offset (hours) like every OFS indicator: RTH Start and RTH End are shown and entered in the chosen zone, while the RTH window stays anchored to the New York exchange clock - switching the zone never moves anything on the chart. The default display here is New York, so charts saved with 1.2.0 keep their hours exactly. The diagnostic group is now 15 - Log.
1.2.0 - INSTANT SETTINGS, LIVE LINES, SIMPLER CONTROL PANEL.
Control panel: one line and no other text - OFS ConfirmedAbsorption, Ratio % with - and + (steps of 100, default 300), ON / OFF, LONG and SHORT. A button that is on is blue, off is grey; - and + flash blue on the click. The Ratio buttons change the same Ratio (%) setting and an open settings window follows them.
Instant: a changed detection or lifecycle setting - and every Ratio click - no longer recalculates the whole chart through the platform. The new levels are built in the background from the stored footprint of the closed bars and swapped in at once: about 0.1 s for nine sessions of one-minute bars, while the chart and the ticks keep running. Entering the licence key no longer triggers any recalculation.
Live lines: the levels are drawn in the platform layer that follows every tick, still behind the candles. An untouched line extends smoothly as price approaches, a hit by the live candle freezes it at once, and Realtime Sequence and Show Provisional candidates appear while the bar is forming - the platform used to refresh them only with a new candle or a chart scroll. The touch marker is now visible on wide lines.
Reload = live chart: the first load scans enough sessions that every level, also in the oldest session shown, is judged against a full Days Look Back history. A reload now gives exactly the levels of a chart that has been running for days - checked on 68,512 real one-minute bars, 34 of 34 checkpoints identical (before, 6.8 % of the live levels differed).
Alerts: they now also fire on charts with bars longer than five minutes (the live check used the bar's open time), and switching alerts or Telegram on in the middle of a session no longer reports older changes at once.
Settings: numbers have no upper limit any more - only a logical minimum (Ratio at least 100, width at least 1, and so on); panel and label offsets are free in both directions. Even extreme values stay fast.
Also: the panel title shows the product name, a narrow chart or a very large strength font no longer replaces the drawing with an error bar, and the manual lists every default value. Detection rules and default values are unchanged.
1.1.4 - MANUAL UPDATE CHECK.
Check For Updates: unticking it and ticking it again now runs the version check immediately and shows the new-version card again, even if you had closed it for that version. Nothing else changed.
1.1.3 - PRODUCT ROW SHOWS THE NAME ONLY.
The Product row in 01 - License now shows the product name only. No internal code is displayed anywhere in the settings. Nothing else changed.
1.1.2 - SETTINGS TEMPLATE: LICENSE HEADER, USED COLOURS INSTEAD OF USED OPACITY, TELEGRAM IN ONE FORM. DETECTION AND LIFECYCLE LOGIC UNCHANGED.
The separate Used Opacity setting is gone: a level that passed a test now has its own Bullish Used Colour / Bearish Used Colour (10 - Visual) with the transparency in the colour itself; every further use fades the level again by the same ratio, exactly as before. Group 01 - License now reads Product, License Key, Website, Version and Check For Updates - the same header in every OFS indicator. The five Telegram rows (Enable Telegram, Bot Token, Chat ID, Get Chat ID Now, Send Test Message) carry the same names, order and help everywhere. Alerts stay off by default.
1.1.1 - CONTROL PANEL DEFAULTS TO TOP CENTRE; INSTANT CLICK FRAME.
The ABS / LONG / SHORT control panel now opens at the top centre of the chart (Control Panel Position in 12 - Control Panel; it used to be top left). A chart that already saved its own position keeps it. The white click frame on ABS / LONG / SHORT now appears on the very next repaint and follows the button (the same mechanism as OFS F4 WaveFade) instead of lagging behind the platform redraw. Detection, lifecycle and drawing logic are unchanged.
1.1.0 - REALTIME SEQUENCE: SEE A CONFIRMED LEVEL DURING THE BAR.
New Detection Mode (08 - Confirmation), off by default. Closed Bar keeps the audited behaviour - a level is confirmed only when the bar CLOSES beyond the zone, never repainted. Realtime Sequence draws the level solid the moment the forming live bar already closes beyond the zone, instead of waiting for the bar to finish; if price returns before the close it retracts. A faster live signal at the cost of intra-bar repainting. Closed history is always Closed Bar, so saved charts and past levels are unchanged.
The closed-bar detection is byte-for-byte identical - proven again by the replay determinism check over 68,512 bars - and five new engine tests cover the confirmed-then-retract flow (69 in total). Default colours stay green and red.
1.0.0 - FULL AUDIT AGAINST THE TECHNICAL SPECIFICATION.
0.2.0 - CONTROL PANEL: ABS, LONG AND SHORT AT ONE CLICK.
0.1.12 - PANEL LAYOUT AND VISIBILITY CONTROLS.
0.1.11 - RELIABILITY AND LIVE-LIFECYCLE AUDIT.
0.1.10 - The update card now describes what a new release brings.
0.1.8 - Recalculation performance was reduced from roughly two minutes to under one second in the 100,000-bar benchmark, and the documented touch, reaction, rearm, touch-limit and break lifecycle was restored.
0.1.7 - Absorption levels and strength labels moved behind the candles.
0.1.0 - First release of the documented, tick-precise confirmed-absorption detector.
- The waiting and error notices are off by default, also on saved charts - switch them on with Show Notices. A missing or invalid licence is always shown.
- Notices start 50 px from the top, below the row of hidden panel buttons (Notice Offset Y), and the notices of several OFS indicators stack below each other by themselves - they never cover a control panel or a hidden panel button.
- The hidden panel button shows a dot before the name: green when anything on the control panel is switched on, an empty grey ring when everything is off - you see at once which indicator draws on the chart.
1.4.7 - THE TIME ZONE ROW SWITCHES TO MANUAL AT ONCE.
- A non-zero Manual Offset (hours) switches Time Zone to Manual. Until now the settings window kept showing the previous zone until it was reopened - now the Time Zone row shows Manual at once.
- Nothing else changes.
1.4.6 - LOG: ONE SWITCH, ITS OWN FOLDER.
- New in 15 · Log: Log (on / off, off by default) and Log Folder. Switched on, the indicator writes everything it does into its own log - its settings and every change of them, the chart, the calculation, the scan of the session window and every rebuild with its duration, every new level and every change of its state, its alerts and errors and what the panel shows. Keys, tokens and IDs are never written.
- The files go into the folder of the indicator inside Log Folder, for example D:\logs\OFS ConfirmedAbsorption - one file per chart and day, with the computer and the platform in the file name.
- Log Folder is now the folder of the log. Export CSV Now writes into the same folder of the indicator (until 1.4.5 into a subfolder named after the computer); Enable Diagnostics and Export CSV Now stay below Log Folder.
1.4.5 - SAVED CHARTS KEEP THEIR RTH HOURS ACROSS THE CLOCK CHANGE.
- A chart saved before this update with RTH Start / RTH End at the default now always loads as 09:30 - 16:00 New York, also when it was saved in summer and opened in winter (or the other way round). Until now the one-time conversion of the old saved value used today's clock offset, so such a chart could start one hour off. Hours you set yourself convert as before.
1.4.4 - RTH HOURS KEEP THEIR TIME AFTER A CLOCK CHANGE.
- RTH Start / RTH End are shown and entered in your Time Zone as before, but the chart now saves them in New York exchange time. Until 1.4.3 a chart saved before a daylight-saving change opened with the regular hours one hour off - for example with Time Zone = Bratislava in the week when Europe and the US change clocks on different dates. A saved chart is converted once on its first load; after that the chart saves New York time and opens with the same hours in summer and winter.
1.4.3 - LEVELS ON 1-HOUR, 4-HOUR AND DAILY CHARTS TOO.
- The window of the first scan and the lifetime of a level are counted in sessions (5 by default). On a daily chart that was 5 candles and almost no level appeared. A session now counts at least 40 candles: on 1-hour, 4-hour and daily charts neighbouring sessions are joined (daily: 40 days per session). 1-minute to 30-minute charts are unchanged.
- The information panel and the notices no longer hide behind an open control panel: where the control panel covered them (top right on a narrower chart), they now sit just below it. Without overlap nothing moves.
1.4.2 - CONTROL PANELS AND HIDDEN BUTTONS LINE UP BY THEMSELVES; EVERYTHING OFF BY DEFAULT.
- The buttons of hidden control panels of all OFS indicators on a chart line up side by side by themselves at the top centre, in the order of the chart's indicator list; open control panels at the same place stack below each other. A different position or offset in the settings keeps a button or panel in its own place.
- New default places, also on saved charts: Control Panel Position Top Center, Offset X 0, Offset Y 40; Hidden Button Position Top Center, Offset X 0, Offset Y 5.
- Every function of the control panel is off by default for a newly added indicator (ON / OFF - Show Absorptions - and the LONG / SHORT line extensions), so a new chart shows nothing until you switch it on. A saved chart keeps its own switches.
1.4.1 - DIAGNOSTICS SHOW WHAT HAPPENED ON THE CHART.
- Enable Diagnostics (15 · Log) lists the confirmed and merged levels and how often each lifecycle step happened (touches, reactions, timeouts, rearms, breaks, expiries); the counts of discarded candidates are no longer shown.
1.4.0 - THE CHART OPENS WITHOUT WAITING; LINES CAN END BEFORE THE RIGHT EDGE.
- Opening a chart no longer waits for the footprint scan of the last sessions: it is built in the background, the same way a changed setting is rebuilt, and the levels appear as soon as it is ready - the same levels as before. Meanwhile the notice (or the panel) says SCANNING. Bars that close during the scan are included.
- New: Line Right Offset (px) in 10 · Visual - the absorption lines, their touch points and strength numbers end this many pixels before the right edge of the chart, so they leave free what you keep there (for example the Depth Of Market). 0 = up to the edge (default).
- Drawing never waits for the calculation: while a bar is being processed, the last finished picture is shown.
- The red outage frame returns to normal after 4 s of healthy data (10 s after lost data or a lost connection) instead of 30 s.
1.3.3 - RED PANEL FRAME WHEN THE CONNECTION OR THE DATA DROPS; LOG FOLDER.
- New: the indicator watches the connection and the market data - the account connection (for example Rithmic) lost for more than 15 s, no market data for 15 s while CME is trading, or the data more than 5 s late. While that lasts, the control panel and the hidden panel button get a thick red frame; everything keeps working, and the frame returns to normal after 30 s of healthy data. No alert and no sound. Setting Control Panel Outage Frame (on by default) in the control panel group.
- New: Log Folder (in the Log group) - the folder for the files written by Export CSV Now, for example D:\logs; the files go into a subfolder named after the computer, so two computers can share one synchronised folder. Empty = the OrderFlowSmith folder in AppData as until now.
1.3.2 - THE CONTROL PANEL ZOOMS TO FIT A NARROW CHART.
- On a chart narrower than the control panel (a smaller monitor, several charts side by side) the whole panel now shrinks evenly - the same buttons in the same places, only smaller, down to font size 6 - instead of running out of the chart or over its own name. It grows back when the chart is wide again and does not jump back and forth near the limit. New setting Control Panel Zoom To Fit (on by default).
1.3.1 - ALERTS: SOUND ONLY, NO POPUP WINDOW.
- When an alert fires, the indicator only plays its sound - no popup window appears on the chart.
1.3.0 - HIDE THE CONTROL PANEL; THE NEW-VERSION CARD POINTS TO ATAS; A SHORTER SETTINGS LIST.
- HIDE next to the panel name hides the control panel: only a small button with the product name (ConfirmedAbsorption) stays on the chart - click it and the panel is back. Hiding changes nothing else: everything switched on keeps working.
- New settings in 12 · Control Panel: Hide Control Panel, Hidden Button Position, Hidden Button Offset X / Y (px), Hidden Button Font Size, Hidden Button Text Color and Hidden Button Background - by default the button sits where the panel sits.
- The new-version card now says that ATAS delivers the new version to your platform automatically (until 1.2.7 it pointed to a download in your account on orderflowsmith.com, which is no longer offered).
- The settings list shows what is yours to tune: the engine internals of the detection and the lifecycle are no longer listed and keep their proven values. Saved charts keep every value.
- 06 · Detection: the choice for prices without volume on the other side is now called Empty Opposite Side - the saved value stays.
- The notice about a short history no longer points to a setting: load more days of history into the chart.
- Setting descriptions and the manual say what each setting changes on the chart.
1.2.7 - PRODUCT NAME IN TELEGRAM, READABLE ALERTS, "AND" INSTEAD OF "&" IN SETTINGS.
- Telegram messages start with the product name [OFS ConfirmedAbsorption] instead of a short internal code.
- The ATAS alert window shows the readable message first, then the machine-readable details with the product name instead of a short code.
- Settings group 05 · Session and Time is written with "and": ATAS X showed the "&" sign doubled (for example "Session && Time") and the classic ATAS hid it.
- Only names changed. Saved settings and chart templates keep all their values.
1.2.6 - ABSORPTION LINES CAN BE EXTENDED TO THE RIGHT.
New Extend Lines Right (px), default 0 = as before: every live absorption level - one price has not come back to yet - is extended to the right by this many pixels beyond its normal end. A fresh absorption at the live candle used to have an almost zero-length line hidden under the candle, so only its strength number was visible; with a few dozen pixels it now shows next to the candle. Levels price already came back to keep ending where they were touched. The provisional run that already confirms on the live bar (Realtime Sequence) is extended the same way. Setting in 10 - Visual.
1.2.5 - THE NEW-VERSION CARD HAS ONLY THE CLOSE BUTTON.
The card announcing a new version no longer has a cross in its top corner - the Close button at the bottom is the only way to close it, the same in every OFS indicator. Closing it still remembers that version, so the card does not come back until the next release. Nothing else changed.
1.2.4 - DRAW ABOVE CANDLES IN THE WHOLE FAMILY; NOTHING OVER THE PANELS OF OTHER INDICATORS.
New setting Draw Above Candles (10 · Visual), off by default: the absorption levels and candidates sit behind the candles; on puts it above the candles. ATAS applies this order to the whole price panel - while ANY indicator on the panel has it on, everything on the panel is drawn above the candles - so the whole OFS family now has the same switch with the same default. Whatever the setting, nothing ConfirmedAbsorption draws on the chart covers the panels and windows of other indicators; only its own panel stays on top.
Fixed: while the price panel is drawn above the candles (this or any other indicator with the switch on) and the chart is scrolled back so that the last bar is off screen, ATAS does not draw the live chart layer at all - the absorption levels and candidates disappeared until the last bar was back in view. In that case the content now goes to the main chart layer, so it is always there.
1.2.3 - CHECK FOR UPDATES CHECKS AT ONCE; THE NEW-VERSION CARD ALWAYS IN THE MIDDLE OF THE CHART.
Unticking Check For Updates in the settings and ticking it again now asks orderflowsmith.com for the latest version straight away and, when a newer version exists, shows the card at once - also on a weekend or in a quiet market with no new ticks. Until now the check started only if the chart happened to redraw between the two clicks, so without ticks nothing happened, and the answer waited for the next redraw. Ticking it again also brings back a card you closed earlier.
The new-version card always opens in the middle of the chart, whatever the position of the control panel or the notices of the indicator. Nothing else changed: the calculation, the settings and saved charts stay as they were.
1.2.2 - CONTROL PANEL ON THE COMMON OFS TEMPLATE.
The one-line control panel is now drawn by the same code as every OFS control panel: Ratio % is a framed card "Ratio % - 300 +", ON / LONG / SHORT are blue when on and grey when off, - and + flash blue on a click - the same look as Entry Desk, AbsorbEntry, FiboLevels and the strategies. It sits exactly in the top centre (offset X 0; it used to be 20 px right of centre), so the FiboLevels control panel fits right under it.
1.2.1 - SETTINGS IN THE COMMON OFS ORDER; CHECK FOR UPDATES ON DEMAND.
The settings window follows the same layout in every OFS indicator: 01 License first (product, key, website, version, Check For Updates), then Session and Time where it applies, the indicator's own groups, and at the end Panel, Alerts, Telegram and Log. Saved charts keep all their values - only names and the order of the groups changed.
Check For Updates now also works on demand: untick it and tick it again and the indicator asks orderflowsmith.com straight away - a new-version card you closed earlier comes back as well. Until now the switch promised this but the check waited for its daily turn.
The strength percentage in the middle of every absorption line now sits on a dark box (Strength Background, default black - transparency is part of the colour, fully transparent = no box), so the line running behind it no longer makes the number hard to read. The same as in OFS Entry Desk.
05 - Session and Time gains Time Zone and Manual Offset (hours) like every OFS indicator: RTH Start and RTH End are shown and entered in the chosen zone, while the RTH window stays anchored to the New York exchange clock - switching the zone never moves anything on the chart. The default display here is New York, so charts saved with 1.2.0 keep their hours exactly. The diagnostic group is now 15 - Log.
1.2.0 - INSTANT SETTINGS, LIVE LINES, SIMPLER CONTROL PANEL.
Control panel: one line and no other text - OFS ConfirmedAbsorption, Ratio % with - and + (steps of 100, default 300), ON / OFF, LONG and SHORT. A button that is on is blue, off is grey; - and + flash blue on the click. The Ratio buttons change the same Ratio (%) setting and an open settings window follows them.
Instant: a changed detection or lifecycle setting - and every Ratio click - no longer recalculates the whole chart through the platform. The new levels are built in the background from the stored footprint of the closed bars and swapped in at once: about 0.1 s for nine sessions of one-minute bars, while the chart and the ticks keep running. Entering the licence key no longer triggers any recalculation.
Live lines: the levels are drawn in the platform layer that follows every tick, still behind the candles. An untouched line extends smoothly as price approaches, a hit by the live candle freezes it at once, and Realtime Sequence and Show Provisional candidates appear while the bar is forming - the platform used to refresh them only with a new candle or a chart scroll. The touch marker is now visible on wide lines.
Reload = live chart: the first load scans enough sessions that every level, also in the oldest session shown, is judged against a full Days Look Back history. A reload now gives exactly the levels of a chart that has been running for days - checked on 68,512 real one-minute bars, 34 of 34 checkpoints identical (before, 6.8 % of the live levels differed).
Alerts: they now also fire on charts with bars longer than five minutes (the live check used the bar's open time), and switching alerts or Telegram on in the middle of a session no longer reports older changes at once.
Settings: numbers have no upper limit any more - only a logical minimum (Ratio at least 100, width at least 1, and so on); panel and label offsets are free in both directions. Even extreme values stay fast.
Also: the panel title shows the product name, a narrow chart or a very large strength font no longer replaces the drawing with an error bar, and the manual lists every default value. Detection rules and default values are unchanged.
1.1.4 - MANUAL UPDATE CHECK.
Check For Updates: unticking it and ticking it again now runs the version check immediately and shows the new-version card again, even if you had closed it for that version. Nothing else changed.
1.1.3 - PRODUCT ROW SHOWS THE NAME ONLY.
The Product row in 01 - License now shows the product name only. No internal code is displayed anywhere in the settings. Nothing else changed.
1.1.2 - SETTINGS TEMPLATE: LICENSE HEADER, USED COLOURS INSTEAD OF USED OPACITY, TELEGRAM IN ONE FORM. DETECTION AND LIFECYCLE LOGIC UNCHANGED.
The separate Used Opacity setting is gone: a level that passed a test now has its own Bullish Used Colour / Bearish Used Colour (10 - Visual) with the transparency in the colour itself; every further use fades the level again by the same ratio, exactly as before. Group 01 - License now reads Product, License Key, Website, Version and Check For Updates - the same header in every OFS indicator. The five Telegram rows (Enable Telegram, Bot Token, Chat ID, Get Chat ID Now, Send Test Message) carry the same names, order and help everywhere. Alerts stay off by default.
1.1.1 - CONTROL PANEL DEFAULTS TO TOP CENTRE; INSTANT CLICK FRAME.
The ABS / LONG / SHORT control panel now opens at the top centre of the chart (Control Panel Position in 12 - Control Panel; it used to be top left). A chart that already saved its own position keeps it. The white click frame on ABS / LONG / SHORT now appears on the very next repaint and follows the button (the same mechanism as OFS F4 WaveFade) instead of lagging behind the platform redraw. Detection, lifecycle and drawing logic are unchanged.
1.1.0 - REALTIME SEQUENCE: SEE A CONFIRMED LEVEL DURING THE BAR.
New Detection Mode (08 - Confirmation), off by default. Closed Bar keeps the audited behaviour - a level is confirmed only when the bar CLOSES beyond the zone, never repainted. Realtime Sequence draws the level solid the moment the forming live bar already closes beyond the zone, instead of waiting for the bar to finish; if price returns before the close it retracts. A faster live signal at the cost of intra-bar repainting. Closed history is always Closed Bar, so saved charts and past levels are unchanged.
The closed-bar detection is byte-for-byte identical - proven again by the replay determinism check over 68,512 bars - and five new engine tests cover the confirmed-then-retract flow (69 in total). Default colours stay green and red.
1.0.0 - FULL AUDIT AGAINST THE TECHNICAL SPECIFICATION.

0.1.12 - PANEL LAYOUT AND VISIBILITY CONTROLS.
0.1.11 - RELIABILITY AND LIVE-LIFECYCLE AUDIT.
0.1.10 - The update card now describes what a new release brings.
0.1.8 - Recalculation performance was reduced from roughly two minutes to under one second in the 100,000-bar benchmark, and the documented touch, reaction, rearm, touch-limit and break lifecycle was restored.
0.1.7 - Absorption levels and strength labels moved behind the candles.
0.1.0 - First release of the documented, tick-precise confirmed-absorption detector.
Frequently asked questions
How is this different from the built-in ATAS Absorption indicator?
The built-in indicator does not publish its internal equation, so OFS ConfirmedAbsorption does not claim to clone it. It uses its own detection on real tick data, followed by mandatory rejection confirmation: a level appears only after price has rejected it.
Why does a huge volume sometimes not get a line?
Because volume alone is only a candidate. The candle must close away from the whole zone by the configured distance. Aggressive volume that price simply runs through is not confirmed absorption.
What data do I need?
A feed that provides Bid/Ask classified executed volume for each footprint price level. If traded candles arrive without usable footprint rows, or the loaded history is too short, the chart shows INSUFFICIENT DATA with the reason instead of inventing zeros.
Does it repaint?
Closed-bar results do not repaint. The optional current-bar preview is dotted and faint, and it never becomes a historical level unless the closed candle passes confirmation. A recalculation or reload produces exactly the same levels as the uninterrupted live chart.
What does Wicks Only mean and why is it the default?
Bullish absorption is only accepted in the lower wick and bearish only in the upper wick. Reversal absorption happens at the extremes - a big volume inside the body is usually rotation, not a passive player stopping the move. All and Body Only modes exist for research.
What does the Ratio setting do?
It sets how strongly the pressure at a price must outweigh the other side before the price can count as absorption. A higher Ratio gives fewer and stronger candidates, a lower one more; the control panel changes it in steps of 100.
What does USED mean?
Price touched the level and then reacted away from it. The level fades - a little more after every further use - but can be tested again once price has moved far enough away. The visible line remains frozen at its first touch.
When does a level disappear?
It expires after the configured session age or after the configured number of successful tests. A close through the zone marks it BROKEN and keeps it dashed for the selected number of bars before removal.
How should I set Minimum Volume for my instrument?
Start with the Hybrid mode: your number acts as an absolute floor and an adaptive percentile of recent aggressive tick volumes raises it to match current activity. Then use the CSV export in Diagnostics to calibrate on your own sessions. There is no universal number and the indicator does not pretend there is one.
Why do the lines change length?
Untouched lines remain short while price is far away and extend smoothly with every tick as price approaches. Their price never changes. The first market return - already by the live candle - freezes the visible end at that bar. The LONG and SHORT buttons of the control panel extend the untouched levels of that side to the current bar instead.
Does it work in ATAS X?
Yes. The same .NET 10 DLL is built for classic ATAS and ATAS X. On macOS it runs inside ATAS X on Apple Silicon; whether it works there depends on the ATAS X runtime and the data feed available on that Mac.
Does a confirmed level guarantee a bounce?
No. It proves that the configured footprint pressure and rejection occurred once. It is a location for analysis, not a promise of future price behaviour.
Why do I see so many lines with the defaults?
The default Ratio, Stacked Levels and Minimum Volume are starting values, not a calibration. Confirm Close Distance 1 is the most permissive confirmation. For fewer and stronger lines raise Stacked Levels to 2, Confirm Close Distance to 2 or more, Ratio or Minimum Volume, and use the CSV export to see which levels actually held on your instrument.
My instrument has other regular hours than the US session.
Set RTH Start and RTH End in 05 - Session and Time. They are shown and entered in the Time Zone chosen there (New York by default) and stay anchored to the New York exchange clock with daylight saving handled per bar, so switching the zone moves nothing on the chart. They define what counts as RTH; regular and extended hours keep separate adaptive volume minimums.
The panel is off - will I still see a problem?
Yes, with Show Notices on (off by default): the INSUFFICIENT DATA and WARMING UP notices have their own switch, Show Notices, with an own position and offsets, and they appear even while the panel is hidden. A missing or invalid licence is always shown.
Does changing a setting freeze ATAS?
No. A changed detection or lifecycle setting, and every click on - or + next to Ratio % on the control panel, is rebuilt in the background from the footprint of the closed bars the indicator already stored. The current levels stay on the chart until the new ones are ready - about a tenth of a second for nine sessions of one-minute bars - and the chart and its ticks keep running.
