Dealer positioning drives explosive moves. Our GEX screener identifies which names are most exposed to a gamma squeeze before the move starts.
When dealers are short gamma, they must buy into rallies and sell into dips — amplifying moves in both directions. GEX shows you when this regime is active.
Black-Scholes gamma computed per strike, aggregated by dealer convention. See exactly where market makers are positioned.
Four-factor weighted blend: negative GEX fraction, call-wall proximity, short-dated dominance, and put/call OI skew.
Call wall, put wall, and gamma flip point — the three strikes that define the current dealer positioning regime.

The screener ranks every name in the watchlist by squeeze score. High scores mean dealers are heavily short gamma — any directional move gets amplified by forced hedging.
Key levels tell you where the fireworks start: the gamma flip (regime change), the call wall (natural ceiling), and the put wall (natural floor).
When you buy an option, your broker's market maker takes the other side. To stay hedged, dealers must continuously buy or sell shares as the price moves — this is gamma hedging. The direction of that hedging depends on whether dealers are long or short gamma.
Dealers are long gamma. They sell into rallies and buy dips — acting as a natural dampener. Price tends to pin near high-gamma strikes.
Dealers are short gamma. They must buy into rallies and sell into dips — amplifying the move in both directions. This is where squeezes happen.
The gamma flip point is the price level where dealers switch from long to short gamma. When spot price crosses below the flip, the squeeze regime activates.
Cross-symbol screener to find squeeze candidates, then drill into per-strike GEX charts for any name.
For each symbol in the watchlist, we pull the full options chain and compute Black-Scholes gamma per strike. Call GEX is positive (dealers long), put GEX is negative (dealers short) by convention.
The call wall (largest call GEX) acts as resistance. The put wall (largest put GEX) acts as support. The gamma flip is where net exposure crosses zero — below this level, dealers switch from suppressing to amplifying volatility.
Four factors combine into a 0-100 squeeze score: negative GEX fraction, proximity to call wall, short-dated dominance, and put/call OI skew. Higher score = dealers are more exposed to forced hedging.
Gamma Squeeze Screener is available on the Pro plan. Know where dealers are trapped.
