GEX Profile

See exactly where dealers are positioned across strikes. When GEX is positive, expect mean-reversion. When negative, expect momentum. This single metric changes how you size and time your entries.

±

Expected Move

Three independent calculations — Straddle Mid, IV Formula, and 16Δ Width — triangulated into one range. Know the market's implied boundaries before the open.

Regime Detection

A 0–100 score that quantifies the gamma environment in real time. Above 50, dealers suppress moves. Below 50, they amplify. Stop guessing the regime — measure it.

Key Levels

Put Wall, Call Wall, GEX Flip, and Max Pain — the four levels institutional desks watch. Updated in real time as positioning shifts.

Call Wall

The strike with the highest call gamma exposure.

Acts as resistance when dealers hedge — price tends to stall here.

Put Wall

The strike with the highest put gamma exposure.

Acts as support when dealers hedge — a floor the market gravitates toward.

GEX Flip

The price where aggregate gamma crosses zero.

Above = mean-reversion. Below = momentum. The single most important level for regime.

Max Pain

The strike where option holders lose the most.

A gravitational pull as expiration approaches — price often drifts toward it.

Expected Move

The market's implied range for the session.

Your benchmark for whether a move is "normal" or "abnormal."

Simple, transparent pricing.
