Dynamic Market Data Subscription May Not Reach the Strategy Engine

Summary

This Chinese-language forum thread raises an implementation issue in quantitative trading software: a contract can be dynamically subscribed to through the engine and strategy code, yet its market data may not arrive at the strategy. The original poster says the subscription itself works, but the strategy does not appear to be connected to the dynamically subscribed quote stream.

A reply suggests tracing the main engine, gateway interface, and strategy engine with diagnostic logging to identify where the data flow breaks. Another participant asks whether the issue was resolved, but the thread provides no confirmed fix, code details, or explanation of the underlying cause. It is therefore useful mainly as a debugging lead: verify subscription handling and message routing across those components, while recognizing that the discussion does not establish a specific diagnosis or solution.

Key ideas

• A successful dynamic contract subscription does not guarantee that quote updates reach a strategy.
• The thread recommends tracing the main engine, interface, and strategy engine with diagnostic output.
• The discussion gives no confirmed fix or root cause, so the suggested debugging path is not a validated solution.
