Every level on the chart marks a price zone where market makers must hedge their options exposure. When price approaches these zones, dealers buy or sell the underlying to stay delta-neutral — creating real, repeatable support and resistance. No guesswork. No trend lines. Just the mechanics of how options work.
Pick any date, hit play, watch gamma shift — hour by hour.

Gamma Exposure shows where options market makers are forced to hedge — creating structural price zones that technical analysis can't see.
