Where dealers sit. Where retail leans.
NET position shows the net dealer book — short or long across the strike chain. When dealers are short, retail is long; the hedge flow follows.
Welcome to the era of AI trading flow
Real dealer flow. Read by AI.
Real market maker positioning — not naive GEX like others. Multi-proprietary flow metrics, every ratio and permutation, read in time series. An AI analyst calls targets, reversals, squeezes, and end-of-day pins as they form — training continuously on every new tick.
GEX shows what's there.
Flow shows what's moving.
Other tools show you a snapshot of dealer positioning. We show you the actual hedging in motion — the ratios, the time series, the moves before they print on the tape.
Built on real-time options chain data. No end-of-day delay.
The five metrics
Beyond GEX. The full dealer flow stack.
Gamma walls and magnets — the gravity wells of the tape.
GEX maps the dealer gamma profile across strikes. Positive gamma damps volatility into walls; negative gamma amplifies into squeezes.
The accelerant. Where flow is about to break.
DEX is our second-order metric — combining vanna and charm. It captures where gamma is about to amplify, before price prints the move.
Vanna in motion. Vol-driven directionality.
VEX tracks the directional sensitivity of dealer hedging to changes in volatility. When VIX moves, VEX shows where the hedge flow goes.
Charm and time decay. The end-of-day pin, before it pins.
CEX captures the charm exposure — how dealer hedging shifts as time decays. By midday it's already telling you where the close wants to print.
Stack any two. Watch the confluence emerge.
Overlay NET on GEX. Pair DEX with VEX. The signal lives in the ratios — not in any single metric. SPX-Flow lets you compose them at will.

Foundations
Naive GEX vs. real MM positioning
Position is the inventory list. Positioning is the forced behavior. Most tools show the first; the trade is in the second.
Read → FoundationsThe five regimes
Every SPX session falls into one of five dealer-flow regimes. Reading the regime first is how you stop fighting the tape.
Read → The MetricsUnderstanding DEX
DEX fuses vanna and charm into one read of where dealer gamma is about to amplify, weaken, or flip.
Read → The MetricsVanna and VEX
VEX isolates the vanna component of dealer hedging. On vol-regime-shift days, it's the metric that explains everything else.
Read → Trading ApplicationSpotting squeeze setups
Squeezes don't come from nowhere. The dealer book signals them 30-60 minutes before the trigger if you know where to look.

The agent learns from real SPX flow. As the data accumulates, the regime calls tighten and the edge compounds.
