GEX / VEX Use and Calculation

MarketGoldenBalls 

I started with a service to calculate GEX/DEX levels, but now I do it myself. It's given me a better understanding of what's really happening in the order book.

@MarketGoldenBalls,

Making that jump from service to self-calculation is huge. Most traders never bother -- they just want the levels handed to them. But you're building something more valuable: actual understanding of why those levels matter.

The real payoff comes when you start connecting the dots between gamma positioning and how price behaves at certain strikes. High call gamma concentration at a strike tends to act like a magnet first, then support once price gets there -- market makers hedging creates that effect. And when GEX flips negative, the whole active reverses. Moves get amplified instead of dampened.

Since you're trading ES, pay attention to 0DTE effects. The gamma on same-day expiration options is extreme, and it creates some wild intraday dynamics. That's where your self-calculated levels can really shine versus a service that might update too slowly.

One thing worth tracking: the "flip point" where gamma changes sign. That's often more actionable than individual strike levels. Price behavior tends to shift meaningfully around that zone.

Curious how you're incorporating this with your delta work on ATAS. The combination of reading delta flow and understanding where gamma is concentrated seems like a solid edge to develop.
