Tools that show their evidence
Every indicator here states what it sees, shows the data behind the verdict and tells you when the feed is incomplete. Browse by category below, or put any tool on a live chart with a free trial.
Where options positioning is likely to brake or accelerate the market. Dealer hedging leaves footprints on the price axis, and these tools put them on your chart as context — not as a signal.
OFS GammaWalls
OFS GammaWalls overlays gamma walls and reference levels reported by your own GEXBot Classic API account onto ATAS. It can show the 0DTE and optional broader data sets, Zero Gamma, major volume and open-interest strikes, live wall-strength changes, and in-memory level history. Independent freshness states, visible failure notices, and configurable price mapping help you judge whether the picture is usable. It is read-only market context, never an order or trading signal.
OFS SessionGamma
OFS SessionGamma draws the three world trading sessions - Tokyo, London and New York - as rectangles on your ATAS chart: side edges exactly on the first and last bar of each session, top and bottom on the session high and low with a configurable tick offset. Each session is anchored to its own city clock, so daylight-saving changes are handled automatically and switching the display time zone never moves a rectangle. Every session can also draw its open and close prices as labelled reference lines, each with its own colour, style and width. Optionally it adds three key options levels from your own GEXBot account: Zero Gamma (yellow), Gamma Positive (green) and Gamma Negative (red). Alerts and Telegram messages for session opens and closes, Zero Gamma crossings, wall moves and data-feed problems are included and switched off by default.
