How It Works
A 5-minute guide to gamma exposure, structural levels, and the gamma regime — plus how GammaLens makes it all visible.
Step 1
When you buy or sell an option, a market maker takes the other side. To stay neutral, they hedge — buying or selling the underlying to offset their risk.
Gamma Exposure (GEX) measures how much hedging dealers need to do at each strike. High positive GEX at a strike means dealers buy dips and sell rips — creating a magnet. High negative GEX means they amplify moves — creating a breakout zone.
This is why price “sticks” to certain levels and “explodes” through others. Not random — structural.
Step 2
GammaLens computes key levels from the options chain that institutional traders watch:
These aren't arbitrary lines on a chart. They're computed from real open interest data and represent where dealers are forced to hedge. Price respects these levels because real money is behind them.
Step 3
The gamma regime tells you how the market will behave — not just where, but how violently.
In a positive gamma environment, dealers dampen moves. They buy weakness and sell strength. Markets pin to strikes and chop sideways.
In a negative gamma environment, dealers amplify moves. They sell into drops and buy into rips. Markets trend hard and break through levels.
Knowing the regime before you trade changes everything. It tells you whether to fade moves or ride them.
