Broker API integration
We connect your strategy to your broker, one broker or several at once, over REST, WebSocket or FIX. Multi-account execution, your risk rules, reconciliation built in.

The connection layer
Every broker's API is different, with different authentication, different order types, different rate limits, different ways of failing. We build a connection layer that speaks each one properly, so your strategy engine stays clean and the broker-specific detail lives in one place. When you add a broker later, we extend the layer rather than rewrite the system.
Multi-broker, multi-account
One system can place orders across several accounts and several brokers, with position sizing and risk limits set per account, not applied identically to all of them. This is the ceiling that no-code platforms hit, and it's the thing we're most often asked to build for desks running money across more than one venue.
Global exchanges, not just brokers
For futures and commodities, the connection often goes to the exchange or its gateway rather than a retail broker. We build for the major venues: CME and Globex, NYMEX, COMEX and CBOT in the US, Eurex and ICE internationally, and NSE and MCX in India, usually over FIX or the exchange's own gateway. The market pages for futures and commodities cover the instrument side. Here it is about the connectivity.
The part that makes it reliable
An integration that only works on a calm day isn't finished. We build for the rest:
- Reconnecting cleanly after a dropped connection, without sending an order twice.
- Handling partial fills, rejections and the broker's rate limits.
- Reconciling the system's view of your positions against the broker's, continuously.
- Margin and buying-power checks before an order goes out.
Interactive Brokers, in depth
Interactive Brokers is our most-requested integration and the channel most of our US work comes through. Off-the-shelf platforms can't connect to the IBKR API the way a custom system can, which is exactly why clients come to us for it. There's a dedicated page on Interactive Brokers integration.
For every other platform and broker we work with, 25+ of them, across the US, India and crypto, see the technology page.
Common questions
- Can you connect to several brokers at once?
- Yes. We build a connection layer that talks to each broker’s API separately, so one system can route orders across brokers, which comes up often when your own clients sit with different ones.
- REST, WebSocket or FIX: which do I need?
- It depends on the broker and your latency needs. REST and WebSocket cover most cases; FIX is for lower-latency or institutional connectivity. We use whatever your broker supports and your strategy requires.
- What about reconciliation and dropped connections?
- Built in from the start. The system reconciles what it thinks it holds against what the broker shows, and reconnects cleanly without double-sending orders. This is most of the real work in a reliable integration.
