Net GEX is positive. Dealer hedging tends to lean against moves here, which usually means calmer price action. That's friendlier for selling premium.

How to Read MDB GEX

Green bars are call gamma, red bars are put gamma, at each strike. The tallest green bar near the price is the call wall, where dealer hedging can slow a rally. The biggest red bar is the put wall, where hedging can slow a drop. The gamma flip is roughly where total GEX changes from negative to positive: above it, moves tend to be damped; below it, they tend to run.

These are estimates. They assume dealers are long calls and short puts, and real positioning isn't public. Treat the levels as context for picking strikes, not as a prediction. More on how GEX is built is on the GEX overview.
