GEX Replay

Dealer exposure through time instead of one snapshot: strike bars played back, chosen strikes as lines, or a time by strike heatmap. It shows where dealers built gamma or delta during the day.

GEXREPLAYREPLAYGEXRGREPLAYCrypto options (BTC, ETH, SOL, HYPE) and US options (45 underlyings).

GEXREPLAY command showing the BTC strike gamma profile at a past moment with the play and scrub bar

Typing it

GEXREPLAYSymbolview=metric=expiry=window=side=band=top=pick=
>GEXREPLAYSPX view=strikes expiry=0dte window=6h
Draws the top SPX 0DTE strikes as gamma lines over the last six hours.

What you see

  • Profile. Play or scrub through frames. Bars are each strike's exposure at that moment, with the HVL and walls on GEX. Speed 0.5x to 4x.
  • Strikes. One line per strike through the window, with end labels and a watchlist. Click a watchlist row to pin a strike.
  • Gradient. Time by strike heatmap of the metric, as level or Δ vs open. DEXMAP opens this view on DEX.

What to look for

  • 0DTE strikes swinging from short to long gamma into the close: a pin building.
  • ATM lines compressing toward zero: thin gamma, so spot moves more freely.

Arguments

view=
profile (default), strikes or gradient.
metric=
gex (default), dex, vanna, charm, vega or oi. US options swap vanna and charm for FLOW POS, the measured dealer position.
expiry= / window=
all (default), 0dte, eow or eom. Window 1h, 6h, 24h (default), 7d or 30d.
side= / band=
net, call or put. Strike band 5, 10 (default), 20 or full percent around spot.
top= / pick=
Strikes view: 3, 5 (default), 8 or 12 lines, picked by top gamma, ATM or biggest movers.

Good to know

  • GEX can be signed FLOW (default, measured tape) or STD. Other metrics use the standard sign.
  • Empty until snapshot history exists for that symbol. Resolution follows the collector, so minutes, not ticks.

How far back does GEXREPLAY go?

Up to 30 days with window=30d, as long as snapshot history exists for the symbol.
