Gamma studies on the chart

The chart picker’s Gamma DP section holds the dealer-positioning studies. They draw on NQ and ES charts, because those are the futures the index options price; on any other chart they say so rather than drawing nothing. All of them share the VeilGEX grammar.

Which options book the chart reads

The chart header carries a chip naming the options book its dealer-positioning studies are built from — NDX or QQQ on an NQ chart, SPX or SPY on ES. Click it to switch, and every gamma study on that chart follows the pick. The basis between the index and the future is measured over the last regular-hours minutes, so the levels sit still across a timeframe change and read correctly overnight.

Veil Gamma Profile

Exposure per strike as terrain at the chart edge: three tiers of colour by share of the visible peak, values at the bar tip, CALL WALL and PUT WALL tags with points-from-spot, the flip as a tick, a square-root scale for a lopsided book, a ±1σ band, and today’s expiry drawn as a core inside every bar. The heaviest-gamma strike is tagged as the magnet.

Veil Gamma Heatmap

Exposure by strike across time. Strikes are binned uniformly and summed so a five-point chain never stacks into fog; the ramp keeps the whole book visible with the heaviest cells lit. Auto reads today’s expiry on a futures chart; the change modes show what was added and removed since the open or over the last N minutes. Rows are straight, tags name the levels at the newest column, and a hover card gives the numbers.

Veil GEX Levels

The levels on the chart as a ledger: every one a row with its name, price and size, tiered by weight, with markers at the chart edge, a regime strip, how many days a wall has held, and an alert when price crosses a wall or the flip. Joined runs show where a level has been the same strike day after day.

Veil Option Profile

Open interest and volume by strike pinned to the chart edge, rows anchored on their strikes, expiry ink nesting today inside the week inside the month, a rail of level chips — ATM, max pain, the heaviest-gamma strike, the expected move — open interest plus what has traded today, the change in open interest since the prior session with an unusual mark where it is several times the strike’s average, and a strike-by-expiry grid. Click the header to change what the rows show: volume against open interest, premium, or a compare mode.

Veil Gamma Bands

The band the options market is pricing, drawn through time: one expected move — roughly the front-expiry ATM straddle — around an anchor. Inside it, the session is doing what it was priced to do; a close outside is the day exceeding its own option pricing.

Veil Gamma Envelopes

The call wall, the put wall and the flip plotted through time as stepped series across every recorded minute of every recorded session, so the chart shows where the walls sat — and when they migrated — while price was trading against them. An optional two-tone wash between the walls splits at the flip.

Veil Gamma Regime

The session’s net dealer gamma as a sub-pane oscillator of signed bars against a hard zero line, with an optional regime wash behind the candles. Above zero the book is long gamma and hedging leans against the move; below zero it goes with it. The sign is the read; the wash only ever encodes the sign and how far past a threshold it sits.

Veil Option Flows

Large options prints marked on the chart at the strike they hit and the minute they hit it: a diamond for a call, a square for a put, sized by premium, with the side, days to expiry and an aggressor estimate on hover.

Veil Options Delta

A sub-pane histogram of the net options delta traded on the chart’s underlying index — per bar, or as a running total across the session. Sustained positive readings mean call-side pressure building through the day; negative, put-side.

Veil Options Volume

How much options business actually traded, minute by minute, split call against put — the participation number the exposure studies never show. A wall that holds while nothing trades into it is inertia; the same wall holding through a volume surge is a fight. The pane prints the running put/call ratio in its header, on contracts or on premium.

Veil QQQ Levels

Listed under Volume & Order Flow rather than Gamma DP, but it belongs to the same family: the whole-dollar QQQ ladder on an NQ chart, SPY’s on ES, through one held ratio. See The Veil studies.
