Simulating Brain-Computer Commands for MQL5 Trade Execution

Summary

This article presents a prototype pipeline for translating symbolic brain-computer interface commands into MetaTrader 5 trade actions. A Python Flask server simulates commands such as buying, selling, closing positions, or holding; an MQL5 Expert Advisor polls the server over HTTP, parses JSON, and passes commands to trading functions. The design separates command generation from order handling, so another source that emits the same protocol could replace the simulator. The article also discusses polling, command deduplication, and a keyboard override.

The end-to-end integration is demonstrated with synthetic commands, not neural signals from a real BCI. Consequently, it establishes a software connection under controlled conditions but does not validate neural decoding accuracy, real-world trading safety, or live BCI latency. The text contrasts the prototype with a gesture-control reference and proposes replaying recorded neural data, applying confidence thresholds, and exploring other transports as future work. Its trading use remains an accessibility concept and system-integration example rather than a tested trading strategy.

Key ideas

  • A simulated command source can demonstrate the path from symbolic intent to MQL5 order handling.
  • The prototype uses a Python server, JSON messages, HTTP polling, and an MQL5 Expert Advisor.
  • Separating decoding from execution allows different upstream command sources to use the same protocol.
  • The implementation includes duplicate-command tracking and a manual keyboard override.
  • Synthetic commands do not establish real neural decoding performance or validate live trading behavior.
