For humans.
And their agents.

Read-only by default. We do not trade for you.

One plane, one camera: the recorded Option Trades page fills with the day's prints as a stat line counts $62.4M of premium for one put, and its first print is lit; the lit print lifts off as a card and lands on its row in the recorded Contract Rank page, which sorts by premium and shows the put as #2; the put's dot flies to the recorded structure chart, whose bars show from the put wall outward, and the wall is marked at $770; the dot lands on the recorded recipe page's symbol pill, the recipe runs and its six figures count in for the session; the dot reaches the recorded Claude Code session, where the same rows land through MCP; the five screens fold into the mark.

    Bring your agent

    Claude Code, Cursor, Codex or OpenClaw query the same tables through MCP.

    Set up MCP

  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.

  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.

  4. The same data, for agents.

    Ask TradingFlow AI about the page, build and edit recipes with it, or connect your own agent through MCP. Read-only by default; it cannot send an order.

  1. Late October 2026: where the data comes from, steadier sign-in

    TradingFlow 0.36.0 adds a public page explaining what each number is made of, lets email-code sign-in recover from an expired attempt, and keeps Option Trades rows in place when you pause Live.

  2. Mid-October 2026: clearer trials and billing

    TradingFlow 0.34.1 makes adding a card during a trial more direct, ends card-less trials cleanly, and shows ended plans in Billing again.
