Tool guide
Gamma Scan
Names sitting on meaningful dealer gamma, where positioning can pin, accelerate, or reverse the underlying.
Open the tool →What it is
Finds stocks with significant gamma walls near current price. Market makers hedge these positions, creating support and resistance at those strikes.
How it works
Finds liquid stocks sitting near a high-open-interest options strike — the "pin." Market makers hedge around it, so the strike acts as a magnet or a wall, and the edge is distance to the pin.
- Call Wall = potential resistance (dealers sell into rallies to stay hedged).
- Put Wall = potential support (dealers buy dips to stay hedged).
- Larger OI = stronger magnet effect.
Reading each result
Score, Bias (BULL ↑C upside target / BEAR ↓P downside support / NEUT), the Target magnet strike, and Distance. Under 2% = pinned and coiled (expect mean-reversion or pin behavior). 3–6% = clean runway to the magnet.
Price often pins near large walls. Breaking a wall cleanly is a strong breakout signal. Walls vanish post-expiration, so check the DTE on the dominant strike.
