For agents: Claude Code's command for the MCP server.

Test app · session Oct 6

One take. A recorded Claude Code prompt asks TradingFlow over MCP to rank SPY contracts by premium for October 6, 2026, and the reply's three rows stream in. A window lands around the reply and it becomes the Contract Rank page, the $655 put still lit in the same place: #2 by premium. A pointer opens the put's 64 trades: $61.3M of its $62.4M traded at the mid. The in-app TradingFlow AI answers a question about the same put on the same page: 101,845 contracts traded; the next session's open interest was 103,995. A click on SPY opens its Symbol view on the Flow tab, $2.05B of premium that session; a click on the GEX tab opens it on its own definition of gamma exposure, then SPY's daily candles for the year, ending between its call wall at $780 and its put wall at $770. The gallery of official recipes opens; Ticker Options Snapshot is picked and runs for SPY and its six figures and its sentence drop in. Dollars traded, trades, contracts traded and the put wall line up over the TradingFlow logo and the trial line. For humans. And their agents. Read-only by default. We do not trade for you.

  1. Read the tape.

    Every print as it hits the tape: side, strike, premium, size and open interest in one row, with the session and date attached, so the move can be checked print by print.

    Test app, session Oct 6, 2026. Option Trades filtered to the SPY $655 put expiring March 19, 2027 and sorted by premium: one print of 100,000 contracts at $6.13 made $61.3M of the day's $62.4M. On the contract's page, open interest that day was 2,455, set before the session opened; the next session it was 103,995, up 101,540.

  2. Rank the money.

    Symbols and contracts ranked by premium for the session, with flow direction, Vol/OI and IV rank beside them, so the one put that took $62.4M stands out from the noise.

  3. See positioning take shape.

    Net GEX and open interest by strike, the walls and the spot on one chart, read as context for the tape rather than as a target.

Questions before you start.

  • What is TradingFlow’s refund policy?

    TradingFlow accepts refund requests for paid subscription charges within 30 days of the charge; AI credits are non-refundable, have no cash value, and are excluded from the refund amount. Email support@tradingflow.com to request a refund.

  • Can I purchase additional AI credits?

    AI credits cannot currently be purchased separately; TradingFlow plans to offer one-time add-on credit packs in the future and will publish availability and pricing before launch.

  • How should day traders use options flow?

    Day traders use options flow for same-session work: rank unusual activity, inspect the live tape, then validate call/put walls before risking capital.
