A 5-minute guide to gamma exposure, structural levels, and why this data gives you an edge — plus how GammaLens makes it all visible.
When you buy or sell an option, a market maker takes the other side. To stay neutral, they have to hedge — buying or selling the underlying stock to offset their risk.
Gamma Exposure (GEX) measures how much hedging dealers need to do at each strike price. High positive GEX at a strike means dealers will buy dips and sell rips there — creating a magnet. High negative GEX means dealers amplify moves — creating a breakout zone.
This is why price “sticks” to certain levels and “explodes” through others. It's not random — it's structural.
GammaLens calculates six key levels from the options chain that institutional traders watch:
These aren't arbitrary lines on a chart. They're calculated from real open interest data and represent where dealers are forced to hedge. Price respects these levels because real money is behind them.
The gamma regime tells you how the market will behave — not just where, but how violently.
In a positive gamma environment, dealers are hedged in a way that dampens moves. They buy weakness and sell strength. Markets chop sideways, pin to strikes, and stay calm.
In a negative gamma environment, it's the opposite. Dealers are forced to sell into drops and buy into rips — amplifying every move. This is when markets break through levels and trend hard.
Knowing the regime before you trade changes everything. It tells you whether to fade moves or ride them.
