About TradingFlow: Real-Time Option Flow and GEX

TradingFlow is a research tool for US options. It shows which symbols and contracts stand out in the flow, the trades behind them, and how each symbol's options are positioned, so you can decide what deserves a closer look.

This site holds the guides, blog, daily Digest and product updates. The app itself lives at app.tradingflow.com. TradingFlow is made by FLOWMAN LLC.

Who it's for

TradingFlow is built for self-directed traders and researchers who care about:

Option flow: what traded, at what size and premium, and how it executed.
Rankings: which symbols and contracts stand out in a session, and how that changes by date and filters.
Gamma exposure (GEX): modeled call and put walls and gamma flip levels, which are estimates and not dealer inventory.

We show the data and say what it cannot prove. A trade does not reveal who placed it or why, so reading it is up to you. TradingFlow does not give trade signals or investment advice, and it does not place trades.

What you can do

Symbol Research: read one stock, ETF or index across six views: Overview, Flow, Positioning, GEX, Vol and Chain.
Option Trades: see individual trades in a Live view during US market hours and a Historical view for past dates, with shared filters and saved views.
Rank Symbols and Rank Contracts: find the names and contracts that stand out, then open them for detail.
Cookbooks: run official reports, called recipes, for the session you choose. Where your account allows it, make a private copy and edit it with AI.
TradingFlow AI: ask about the page you are on, with answers in text, charts and tables.
MCP: connect Claude, Cursor, Codex or OpenClaw to the same data. The default connection is read-only.
Watchlists: save the names you follow. They appear on Home and in the ticker tape.

The Changelog lists what has changed, and the Roadmap lists what comes next.

How access works

Home, the guides and the glossary are open without an account. Sign in, free, to save watchlists.

Option Trades, Rank, Symbol Research, Contract Research and Cookbooks need a trial or paid plan, and show no market data without one. Eligible new accounts get seven days of full access with no card, and a trial without a card ends on day seven rather than charging you. AI Chat, recipe editing and MCP also depend on your account, and in-app AI replies use AI credits. Pricing has the plans.

Data and transparency

TradingFlow has two kinds of data, on different clocks. Flow is trades as they print, and it updates during the session. Chain data, such as open interest, Greeks and modeled GEX, comes from dated snapshots and is not recalculated tick by tick.

Pages name the session they show, so check it before reading a number. Flow and Chain explains which tool uses which.
