Crypto Options Gamma Exposure: How to Read the Data With Price Context
Gamma exposure estimates how much option hedgers might buy or sell as price moves. It's a model built on open interest and an assumption about who holds the options.
Short answer
Gamma exposure (GEX) sums, across strikes, gamma × open interest × contract size × spot² (with a scaling), signed by an assumption about dealer positioning. Positive aggregate GEX under that assumption implies hedgers sell rallies and buy dips (dampening); negative implies they chase moves (amplifying). ChartsPod's options workspace lists exposure and zero-gamma analysis. Read GEX with price: it matters most near large strikes and close to expiry, and it shifts as OI changes.
How it's built
| Input | Source |
|---|---|
| Gamma per option | Greeks (e.g. Deribit ticker) |
| Open interest | Per instrument (coins) |
| Spot | Underlying price at snapshot |
| Sign | Positioning assumption |
Exposure figures need an assumption about who holds each option (commonly: dealers are short what customers bought). Public open interest doesn't reveal positions, so treat dealer-exposure numbers as model outputs.
Price context
| Regime (model) | Expected hedging |
|---|---|
| Positive GEX | Sell rallies, buy dips |
| Negative GEX | Buy rallies, sell dips |
| Near expiry | Effects concentrate |
