Methodology and glossary

What the numbers mean
Read the methodology
GEX (gamma exposure)
An estimate of the hedging option dealers have to do as the index moves, summed over every strike from open interest and option gamma (gamma × open interest × 100 × spot² × 1%). The usual naive convention is used: dealers are long calls and short puts, so calls count as positive and puts as negative. Net GEX is shown in billions of dollars per 1% move, for all expiries and for 0DTE (options expiring today) separately.
Zero gamma (flip)
The index level where aggregate net GEX changes sign, found by recomputing every option’s gamma on a grid of prices around the current spot; when there are several crossings the one nearest spot is used. It is the line between the two regimes.
Call wall
The strike with the largest positive net gamma exposure. Dealer hedging tends to sell into rallies near it, so it often acts as resistance or a magnet.
Put wall
The strike with the most negative net gamma exposure. It often acts as support, and a break below it can speed a sell-off up.
Regime
Positive gamma (price above zero gamma): dealers hedge against the move, buying dips and selling rips, so price tends to be mean-reverting with tighter ranges. Negative gamma (price below zero gamma): dealers hedge with the move, so price tends to trend and ranges expand. The badge shows all expiries on the left and 0DTE on the right; they can disagree.
Data source
Free, delayed (about 15 minutes) CBOE option chains for SPX and QQQ. Strikes are converted to ES and NQ futures prices at run time: ES with an additive SPX basis, NQ with the NQ / QQQ ratio. The cards show futures prices large and the index price beneath; the GEX Levels Live string stays in index terms and converts on the chart.
Schedule
Levels are computed at 09:07 ET (before the RTH cash open) and 17:37 ET (for the Globex evening session), Monday to Friday. Each date has at most one official RTH and one official Globex session; manual reruns are not listed.
