About This Data
Built from the latest end-of-day options snapshot to help frame dealer positioning.
What this view measures

GEX and DEX are aggregate dealer-exposure estimates derived from the end-of-day options chain. They are context tools for positioning, not live per-contract greeks.

How traders usually read it

Positive GEX can point to more dampened price action, while negative GEX can make breaks more reactive. DEX helps flag whether hedge pressure leans more directional.

What to keep in mind

Vanna and charm can shift quickly as spot moves and time decays, so use walls and clusters as reference zones rather than hard support or resistance.
