“IBKR doesn't allow out-of-the-box apps like MT4/5 to connect to their API, so Trade Vectors built a completely custom app for me. It's a marathon rather than a sprint.”

Why people come to us for IBKR specifically
Interactive Brokers has one of the most capable APIs in the business, and one that off-the-shelf platforms can't tap into. If your strategy lives in MetaTrader, TradingView or a spreadsheet today, connecting it to IBKR properly means custom software, not a plugin. That's most of what we're asked to build here: a system that runs your logic directly against the IBKR API, unattended, reliably.
What we build on the IBKR API
- TWS API and IB Gateway. Systems that run against Trader Workstation or headless via IB Gateway, so your strategy trades without a person watching.
- FIX connectivity where you need lower latency or an institutional setup.
- Multi-account execution. One system across several IB accounts, with per-account risk, what prop desks and small managers usually need.
- Every order type your strategy uses, plus the risk checks that run before an order leaves.
The IBKR-specific engineering
Building well on IBKR means handling the things its API actually does, not a generic idea of “a broker connection”:
- Pacing violations, staying within IBKR's request limits so the connection isn't throttled.
- Reconnecting to TWS or IB Gateway after a restart or nightly reset without losing state or double-sending orders.
- Reconciling positions and open orders against what IBKR reports, continuously.
- Handling partial fills and the API's asynchronous, event-driven order updates correctly.
This is the unglamorous half that decides whether a system survives a live market. It's also why “can AI do this now?” misses the point, the strategy might be simple; running it correctly against IBKR with real money is engineering.
In any language IBKR supports
The IBKR API works with Python, C++, C#, Java and more. We pick the language your setup and latency budget call for, Python for most systems, C++ when microseconds matter. See the full picture on the technology page, or the parent broker API integration service.
Common questions
- Can you connect my strategy to Interactive Brokers if MetaTrader can’t?
- Yes, that’s a common reason clients come to us. IBKR doesn’t let off-the-shelf platforms like MT4/5 connect to its API, so we build a custom application that does exactly what your strategy needs.
- Can you run several IBKR accounts from one system?
- Yes. One system can place orders across multiple IB accounts, with position sizing and risk limits set per account, which is what prop desks and small managers usually need.
- TWS API, IB Gateway, or FIX?
- Whichever fits. The TWS API (via Trader Workstation or IB Gateway) covers most cases; FIX is available for lower-latency or institutional setups. We choose based on your latency budget and how the system needs to run unattended.
