Mirror trades across unlimited accounts with one API call. One API key, no OAuth — built for prop firm scaling.
Building a trade copier from scratch means solving broker connections, order sizing, and bracket handling for every broker you support. Our trade copier API gives you that infrastructure as a service — just make an HTTP request and we handle the rest.
Set up a copy group in the app with a leader and follower accounts, then place orders on the leader through the API, and every trade on the leader is mirrored automatically. Scale from one account to one hundred without writing a single line of infrastructure code. The API supports market orders, limit orders, stop orders, and full bracket orders with take-profit and stop-loss.
Each follower account has its own whole-number copy ratio. If your leader buys 5 NQ contracts, Follower A at x1 copies 5 contracts, Follower B at x2 copies 10, and Follower C at x3 copies 15. Ratios and lockouts are set per follower in the app.
When something goes wrong, the API tells you. Send an Idempotency-Key header so a retried request never places a second order. Broker rejections come back in the response, and the live /stream endpoint reports orders, fills and positions as they change. Locked accounts refuse API orders, and your prop firm's daily loss limit is enforced by the firm at the broker.
Getting started is one HTTP request. Authenticate with an X-API-Key header — no OAuth flow, no WebSocket session to manage — and POST an order to /api/v1/accounts/{id}/orders. The same call works whether the account sits on Tradovate or Rithmic, because the API normalizes every broker behind one interface. Full endpoint reference and Python, Node.js, and cURL examples live in the API documentation.
A trade copier API lets you mirror orders from one account to many programmatically. Instead of building broker connections and order sizing yourself, you make REST calls and Signal Trade App copies each trade to every follower account across any supported broker.
Authenticate with an X-API-Key header, set up a copy group with leader and follower accounts in the app, and either place orders via POST /api/v1/accounts/{id}/orders or let the leader account drive copies automatically. No OAuth or WebSocket code required.
Yes. The API works across Tradovate and Rithmic, which covers firms such as Apex, Lucid Trading and MyFundedFutures. It does not connect to Topstep. Confirm your firm permits automated and copied trading first.
There is no separate API fee. Start with a 5-day free trial (no charge until it ends), then $29/month, for unlimited accounts and API calls. A $599 self-hosted lifetime license is also available.
