Workflow
How it works
From live options chains to gamma exposure by strike, here is what you get on every screen and chart.
📡
Live options data
US options chains refreshed every 15 minutes during market hours, not stale end-of-day snapshots.
∂
Black-Scholes gamma engine
Per-strike gamma is computed with a Black-Scholes model, then combined with open interest: calls add positive exposure, puts add negative. No assumption about which side is a dealer.
⚡
Intraday positioning
Flip levels, call and put walls, and net GEX update through the session, so what you see reflects the latest open interest, not yesterday's close.
