Most retail traders stare at moving averages and RSI while market makers use gamma exposure to pin price to specific strikes.

Here's the thing — when net GEX is positive, dealers are long gamma. They buy dips and sell rips, compressing volatility. The market feels "sticky." When GEX flips negative, dealers are short gamma. They sell into selling and buy into buying, amplifying moves. That's when you get the 2%+ days that blow up accounts.

Understanding where these gamma walls sit gives you:

• Key support/resistance zones that actually hold (because dealers are hedging there)

• Volatility regime awareness — know when the market is primed for a big move vs. a chop day

• Better entries — stop buying right into a negative gamma pocket

I've been mapping these levels daily and sharing them with a group of options traders. If you want the edge that dealers have, Gex Levels breaks it down every morning before the bell.
