Alpaca paper trading · no real money

Say it in plain English. Approve it. Then it trades.

TradeMind turns "buy $500 of AAPL if it drops below 180" into a structured, priced trade proposal. The AI can only stage proposals through validated tools — nothing reaches Alpaca until you click Confirm, and deterministic guardrails run after that.

Plain-English agents

Write your strategy the way you'd explain it to a colleague. The agent turns it into concrete, symbol-level trade decisions each run.

Deterministic risk guard

Position size, trades per run, daily loss and long-only rules are enforced server-side. The AI can propose; only the guard can release an order.

Full audit trail

Every decision stores its reasoning, confidence, risk verdict and resulting Alpaca order id — so you can see exactly why a trade happened.

How a run works

  1. 01

    Ask

    Describe the intent in chat. The agent asks a clarifying question instead of guessing.

  2. 02

    Tool call

    It calls named backend tools — account, positions, market data — then stages a proposal. It can never place an order itself.

  3. 03

    Confirm

    You see symbol, size, order type, estimated cost and the agent's why. Confirm or reject.

  4. 04

    Guarded execute

    Server-side guardrails cap order size at 10% of buying power and daily order count, then the paper order is submitted and logged.
