Follow the complete relationship between price, options flow, implied volatility and positioning.

Move from market-level context to the individual option contract without leaving your workspace.

Every chart, metric and analytical view is built around a shared market timeline.

01Modules

Built around the speed and structure of the 0DTE market.

01Tape & Sweeps

Read the options tape beyond raw prints.

Detect coordinated sweep activity and visually isolate high-impact transactions.

Combine trade size, execution location, timing and contract identity in one tape.

Move from isolated trades to repeatable flow patterns.

02Open Interest Structure & Premarket Map

See where overnight options structure is concentrated before the session begins.

Identify Call Wall, Put Wall, Gamma Flip and Max Pain through a minute-by-minute structural heatmap.

Use open interest as a nightly structural reference, clearly separated from live intraday flow.

Start the session with a structured map — not a directional prediction. Every Open Map is frozen before the session begins to prevent future-data contamination.

02Analytical Heatmap

Analytical Heatmap: GEX and Charm.

One of the platform's most powerful visual tools: it projects the options structure directly onto the same time and price axes as the underlying market.

All adjustments are applied live. The chart, historical series, options flow and every other active indicator continue updating independently in the background — the panel changes only how analytics are visualized; it never rewrites or deletes the underlying data.

GEX and Charm heatmap over live price — contrast, threshold and expiration changed in real time.
GEX / Charm
Switch in real time between GEX — the distribution and concentration of gamma exposure — and Charm, visualizing how time decay can alter delta-related hedging pressure across price levels. Scope to 0DTE / front expiration, all available expirations or a specific expiration.
Live controls
Contrast changes the visual intensity — emphasize the strongest concentrations or reveal weaker structural areas. Peak/Trough Threshold sets the minimum significance for a peak or trough to be highlighted, filtering noise and isolating the most relevant structures.
Peaks, troughs & zero-transition
The heatmap tracks positive concentration peaks, negative concentration troughs and the zero-transition curve. Move from GEX to Charm, change expiration, modify intensity and filter significance without interrupting the feed or losing accumulated data.

Live candle formation inside the heatmap.

Unlike conventional options heatmaps that display only completed one-minute candles or refresh through periodic snapshots, this heatmap shows the complete formation of the current candle in real time — the candle does not suddenly appear when the minute closes.

The update frequency is driven by the actual incoming market-data feed: if a new price is received every 100 milliseconds, the active candle evolves at that same source frequency instead of waiting for the next one-minute close.

Watch the candle open and develop in real time — intraminute movement, continuous changes to the high and low, the evolving body and wicks.

See live price action interact with GEX or Charm concentrations — reactions around peaks, troughs and zero-transition areas as they happen.

Change GEX versus Charm, expiration scope, contrast and peak significance while price builds inside the field — without restarting the chart, interrupting the feed or resetting the active candle.

The heatmap provides the structural options context; the live candle reveals how price is reacting to that structure throughout the entire minute — not just after the move has already occurred.

03Overlay

Real-time chart overlay customization.

The Overlay panel allows every chart to be transformed in real time — without reloading the page, resetting the timeline, interrupting the live feed, or modifying any data already collected.

Every overlay configuration belongs exclusively to that chart: two charts of the same market can display completely different analytics, expiration filters and visual settings while continuing to use the same uninterrupted market-data history.

Overlay panel — levels, maps, flow, heatmaps, bubbles and Greek profiles applied live to a running chart.
Price & reference levels
Instantly enable Implied Move and one-standard-deviation levels, Previous Day High and Low, session VWAP where exchange-volume data is available, and Max Pain for 0DTE, all tracked expirations or one exact expiration. Levels stay anchored to the chart's native price axis through zooming and panning.
Premarket Session Map
For SPX, display the Inferred Hedge Map directly over price — Open Map, Live Map or Open-versus-Live comparison. Switch the model in real time between OI Structure, Inferred Flow and their confluence, with base, compression or expansion volatility scenarios and low, medium or high confidence filters. Balance, Test levels, zones and sticky areas are model-derived — never observed dealer inventory.
Flow overlays
Strike centroids, cumulative flow, delta-adjusted flow and Flow by Strike for the active 0DTE or front expiration — switchable instantly between Net, Total, Directional, Call versus Put and Live Open Interest. Strike levels remain attached to their prices, never moving independently from the axis.
Historical heatmaps
GEX or Charm rendered behind the price action, weighted by Open Interest or inferred Flow. A separate categorical 0DTE heatmap marks Call Wall, Put Wall, Gamma Flip and Max Pain — the strikes with the largest aggregated 0DTE Open Interest, not confirmed dealer positions.
Tape bubbles
Options transactions rendered on the chart as dynamic bubbles — filtered by expiration; all trades, buys or sells; all contracts, Calls or Puts; sweeps only; minimum premium and bubble opacity. Isolate the activity relevant to the current analysis without removing or altering the underlying tape history.
Gamma Flip & Greek overlays
Gamma Flip from Open Interest-based or flow-based Gamma (GEXf), current or historical, scoped to 0DTE, all tracked or one exact expiration. Attach a classified Greek profile to the price axis — GEX, flow-based GEX, Delta, Gamma, Vega, Theta, Charm and flow-based Charm — every metric and expiration independent for each chart.
Volatility & positioning overlays
Volatility Surface, Bubble Positioning and Bubble Hedge, with independent positioning and Gamma Flip expiration scopes — all combinable with price levels, flow, tape bubbles and Greek overlays without replacing any existing layer.
03Greek Ladders & Profiles

Map Delta, Gamma, Vanna, Charm and Convexity across the strike ladder.

Separate call, put and net exposure — and identify major gamma levels and call-versus-put GEX imbalance.

View Aggregate DEX as separate Call, Put and Net components.

Explore the entire options profile through one unified analytical structure.

04Convexity

Measure gamma flow at the individual trade level.

Detect Convexity Peaks as they develop inside the market timeline — and distinguish isolated peaks from sustained convexity bursts.

Monitor Convexity Baseline, Burst Ratio and Long/Short Convexity regimes.

See when options activity may be amplifying or absorbing the underlying move.

05Flow by Strike

See where options activity is concentrating across the index price scale.

Track the most bought and sold 0DTE options by volume, open interest, net flow and total flow — and open multiple live contract charts directly from the rankings.

Anchor flow directly to the corresponding strike levels on the underlying chart.

Switch between net and total flow without changing the market context.

Identify the strikes where activity is accelerating, fading or becoming one-sided.

06Volatility Intelligence

Place every index move inside its volatility regime.

Monitor VIX, VVIX and VXN alongside their corresponding benchmarks.

Track volatility velocity, reversal conditions and regime transitions — detect when VVIX is rising while VIX remains flat.

Combine SPX and VIX options analytics inside the same workspace.

07Positioning Analytics

Explore inferred options positioning by strike, expiration and two-dimensional grid.

Move between Position by Strike, Position by Expiration and Position Grid without changing the underlying dataset.

Analyze inferred customer positioning and the corresponding opposite dealer hedge map.

Compare current positioning with bounded scenario views for spot and volatility changes.

04Workspace

Build the trading screen around your process.

Drag, dock, resize, split and group every chart and analytical panel. Every panel retains its own market, expiration, overlay and visualization settings.

Layouts
Vertical, quadrant, 9-panel and 12-panel layouts. Move entire docks or swap panel positions instantly. Lock the layout without disabling chart interaction.
Presets
SPX 0DTE Execution · SPX Positioning Map · SPX + VIX Regime · VIX Options Desk. Replace your workspace or add a preset to your existing layout — and save your own.
Continuity
Hidden does not mean disconnected: data and shared analytics keep updating while a panel is not visible. Switching markets never resets panels already open.
Persistence
Your workspace remains local, persistent and independent from market data. Keep SPX, VIX, NDX and individual option contracts visible at the same time.
05Replay

Replay the market — not a video of the market.

Deterministic replay turns every captured session into a reusable research environment. Compare trading decisions against the exact market information available at that moment.

Reconstruct an entire trading session from the original ordered market events — through the same pipeline used during the live session.

Pause, seek and accelerate the session while preserving event order. Rebuild indicators as if the market were open again.

Every replay carries explicit quality information, including missing inputs and detected gaps.

06Architecture
Market data is ingested once, calculated once and distributed efficiently to every authorized user.
Heavy analytics are shared by calculation key instead of being recomputed for every browser.
Bounded queues and latest-value delivery protect the platform from slow clients.
The browser receives analytical results — never raw credentials or provider tokens.
07Method

We show what is observed, what is calculated and what is inferred.

Agreement between models is measured and reported; it is never presented as certainty. Market structure is evidence, not a prediction.
