Using GEX & DEX individually
Which lens to reach for, for which question.
You do not always need both. Each metric is the better standalone tool for a different class of question.
Reach for GEX alone when…
- You are deciding how to trade, not what: sizing, stop width, and whether to fade or follow moves all hang on the gamma regime.
- You need intraday levels, the flip level and the call/put walls are actionable support/resistance on their own.
- Volatility is the trade: positive gamma sells it, negative gamma buys it.
Reach for DEX alone when…
- You are handicapping direction and crowding: which side is heavy, how one-sided the chain is, and where the squeeze risk lives.
- You are tracking positioning over days, the trend and sign-flips of Total Net DEX are a swing-timeframe signal, where GEX is mostly a today signal.
- An expiration is approaching and you want to know how much hedge flow rolls off, and in which direction, that is delta notional, not gamma.
