Advanced FMZ Strategy Techniques for APIs and WebSockets
Summary
This platform tutorial describes ways to build customized trading strategies beyond a platform’s standard exchange interface. It covers reading raw REST responses, querying public endpoints, and using authenticated API calls for operations that are not directly supported by the platform’s wrappers. It then introduces WebSocket connections for streaming market data and account or order updates, including subscriptions, reconnection, authentication examples, and continuously reading messages. The discussion explains how queued messages can accumulate when strategy processing is delayed, and contrasts cases where historical messages matter with cases where only the newest quote is useful.
The material is primarily a programming guide with platform-specific examples, not a trading strategy evaluation. It provides no backtest or evidence of improved returns, and the supplied document is truncated before all WebSocket guidance is visible. Authentication details, exchange API behavior, reconnect handling, and message freshness require careful adaptation to the target venue and runtime. Promotional material later in the text does not add evidence about strategy performance.
Key ideas
- Raw REST responses can expose fields omitted by a platform’s normalized interface.
- Public data can be queried separately from authenticated exchange endpoints.
- WebSockets can stream market and account events with lower latency than repeated REST polling.
- Subscription and reconnection behavior depends on the exchange and may require strategy-side handling.
- Queued messages can become stale when order processing slows, so the appropriate read behavior depends on the data type.
