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 pub/sub, order sizing, failure retry, and risk management for every broker you support. Our trade copier API gives you all of that infrastructure as a service — just make an HTTP request and we handle the rest.
Create a copy group via API, add leader and follower accounts, 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 can have its own copy ratio, risk limits, and maximum quantity constraints. If your leader buys 5 NQ contracts, you can configure Follower A to copy at 100% (5 contracts), Follower B at 50% (2 contracts), and Follower C at 200% (10 contracts). All of this is configurable through simple REST endpoints.
When something goes wrong, the API handles it gracefully. Network timeouts trigger automatic retry with exponential backoff. Broker rejections are logged and surfaced via webhook so your system knows immediately. Daily loss limits and profit targets are enforced at the broker level before every copied order, protecting your accounts from runaway trades.
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, Rithmic, NinjaTrader, or ProjectX, 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 pub/sub, order sizing, retry, and risk logic 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, create a copy group with leader and follower accounts, 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 copies across Tradovate, Rithmic, NinjaTrader, and ProjectX, which covers most prop firms including Topstep, Apex, and MyFundedFutures. 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 $30 for the first month and $15/month after for unlimited accounts and API calls. A $599 self-hosted lifetime license is also available.
