Converting Quantitative Rules into 24/5 MetaTrader 5 (MT5) Execution Daemons

The Python-MT5 Integration Architecture

MetaTrader 5 provides a native Python package allowing programmatic account authorization, historical tick retrieval, and direct order placement. In production, however, the terminal connection can drop due to broker server restarts, weekend market freezes, or latency spikes.
