This invention discloses a resource-optimized order execution system for high-frequency trading, comprising a signal receiving and parsing module, a decision and resource management engine, and an order instruction gateway. The system operates in a decision cycle of fixed duration T, maintaining a cycle number t that increments at the beginning of each cycle. The signal module starts in the t-th cycle, receiving and parsing the return rate and transaction probability prediction signals for that cycle. The decision unit judges the signals based on a preset threshold: if the return rate triggers a directional warning or there is a place to place an order that meets the probability threshold, it outputs an allow instruction signal; otherwise, it outputs a suppress instruction signal. When the resource scheduling unit receives the suppress signal, it immediately reallocates the resources of the order chain to the signal module. The order instruction gateway generates and sends a fixed number of orders only when it receives the allow signal; it disables the function when it receives the suppress signal. This system realizes dynamic optimization and collaborative scheduling of computing resources.
