About TradingFlow
Real-time option flow analysis, institutional tracking, and advanced market rank metrics. See what smart money is doing.
TradingFlow is a platform for options flow and gamma intelligence. We help you see where institutional and unusual activity is concentrated, how markets are positioned, and how gamma exposure can influence price — so you can research flow and rank opportunities with clarity.
This site is where we share product updates, the roadmap, and articles on how to use the tools. The app itself lives at app.tradingflow.com.
Who it's for
TradingFlow is built for traders and researchers who care about:
- Option flow — Who is trading what, at what size and premium, and whether that flow is likely opening or closing positions.
- Market rank — Which names are dominating flow by premium, volume, or delta impact, and how that shifts by date and filters.
- Gamma exposure (GEX) — Where dealer hedging pressure sits (call and put walls, zero-gamma level) and how it can support or resist price.
We focus on data and metrics (premium, size, sentiment, delta exposure, gamma) and leave the interpretation to you.
What you can do
- Option Trades — 6 live market KPI cards (Call Flow, Put Flow, Bullish, Bearish, Smart Money, OTM Moneyness) plus a 13-dimension filter panel (Type, Side, Moneyness, Trade Type, 9 numeric ranges). Save your filter preferences and export results (with a subscription). Switch to Live Flow mode to stream trades in real time via WebSocket.
- Market Rank — See symbols ranked by options premium for any trading date. The full ranked dataset is available to all users; date picker, numeric range filters, and CSV export require a subscription. Click any row to open a per-symbol inspection drawer.
- GEX Screener — Rank symbols by dealer gamma (gross, net, or distance to flip) from the latest option-chain snapshot. Inspect any symbol's call wall, put wall, flip line, and full GEX surface (premium) in a compact drawer.
- OI Change Rank — Six rank modes across 1D/3D windows surface OI builds and unwinds. Symbol drawer has four tabs: Overview, By Expiry, By Strike, and Composition analysis. Uses T+1 option-chain snapshots.
- Volatility Desk (coming soon) — A ranked workspace for implied volatility, IV percentile, IV-HV spread, skew, term structure, and earnings-event analysis across the full universe.
- Watchlist — Keep a single list of symbols you care about; use it across Option Trades, OI Change Rank, GEX Screener, and Market Rank. Sign in to save your list; guests see a default list only.
We are always refining these tools and adding new ones. The Changelog and Roadmap describe what’s new and what’s next.
How access works
You can explore the app without signing in: you’ll see a preview of option flow with limited rows. To save your watchlist and preferences, sign in (free). For full flow data, live stream, Market Rank, and exports, a subscription is required. We keep the access model simple: guest, free, and premium — so you know what you get at each step.
Data and transparency
Flow data is aggregated so you can spot block and unusual activity without noise from tiny fills. Where we use option chain snapshots (e.g. GEX Screener, OI Change Rank), we label them clearly: metrics are from the prior close (T+1), not live intraday. We believe in showing the data horizon and caveats so you can interpret results correctly.
