Price Chart (always on top)
Candlestick chart with GEX-derived levels overlaid (Call Wall, Put Wall, Vol Trigger, Hedge Wall, magnets). Includes a Time Machine feature to replay historical GEX snapshots against price action. Toggle overlays with the settings button. The price chart stays visible across every tab so you always have price context.
GEX by Strike
Bar chart of gamma exposure at each strike price, split by calls (green) and puts (red). Shows where dealer hedging is concentrated. The tallest bars are strikes where large open interest creates the strongest hedging flows.
Spot GEX
Net gamma exposure (calls minus puts) at each strike, plotted against the current spot price. Reveals whether dealers are net long or short gamma overall, and highlights the key levels: Call Wall, Put Wall, Vol Trigger, and Hedge Wall.
Momentum
Tracks how total GEX is changing over the day, computed from 3-minute snapshots. The line shows the cumulative delta from the opening GEX baseline (in billions). Rising = dealers adding gamma (more hedging pressure). A FLATTENING signal indicates momentum is stalling, which can precede a regime shift or breakout.
Flow
Real-time options order flow from the OPRA trade stream, classified as buy or sell using the Lee-Ready algorithm. Green/red bars show incremental volume per interval; the blue line is cumulative net flow (buys minus sells). This is our volume-based OI proxy — since 0DTE positions all opened today, cumulative flow approximates live open interest. The orange dashed BVC line is an alternative bulk volume classifier for comparison.
Squeeze Watch (header button)
Scans for gamma squeeze candidates across the market — stocks with high call gamma concentration combined with elevated call volume. Symbol-agnostic, so it lives behind the Squeeze button in the top-right header rather than in the tab strip.
Momentum vs Flow: Momentum measures changes in the GEX structure (are dealers adding/removing hedges?). Flow measures the direction of new trades (are traders net buying or selling options?). They can diverge — e.g., heavy selling flow can increase dealer gamma if sellers are opening new short positions that dealers must hedge.
