Broker Integration
Connect your bot to your broker — without rewriting your strategy
Kingsley Practice's standardised connector layer handles the translation between your rule set and your broker's order API.
How the connector layer works
Your strategy and risk modules speak a normalised internal order format: instrument symbol, direction, quantity, order type, and optional limit price. The connector layer translates this format into the specific API calls required by your broker — Interactive Brokers TWS API, Alpaca REST, Binance futures WebSocket, or a FIX 4.4 session for institutional brokers. When you switch brokers, you select a different connector in your dashboard; your strategy configuration does not change. Execution logs always show both the internal order object and the broker's acknowledgement response, so you can verify that what you instructed is what was submitted.
Supported connections and what each covers
All connectors are tested on live and paper-trading endpoints before release.
Interactive Brokers
Supports equities, futures, options, and forex via the TWS API. Paper trading account connection is available for validation before going live. Session heartbeat monitoring included.
Alpaca Markets
Commission-free US equities and crypto via Alpaca's REST and WebSocket APIs. Supports fractional shares and extended-hours orders where the strategy permits.
Binance Futures
USDⓈ-M and COIN-M perpetual futures via WebSocket order stream. Supports cross and isolated margin modes, with margin type surfaced in the risk dashboard.
FIX 4.4 (institutional)
For traders with direct market access through a prime broker or clearing firm. FIX session configuration, reconnect logic, and message logging are managed by Kingsley Practice engineers.
I moved from Interactive Brokers to Alpaca when IB raised its minimum. The switch took about 20 minutes in the Kingsley dashboard — select the new connector, paste the API key, run a paper trade to confirm the order format, and go live. My strategy rules didn't touch.
