Building a Multi-Currency RSI Crossover Expert Advisor in MQL5

Summary

This article describes an MQL5 Expert Advisor that monitors multiple forex and metal symbols from one chart and generates signals when a fast RSI crosses a slow RSI. It explains symbol selection modes, including trading the chart symbol alone or choosing specified symbols, and includes trading-session controls. Trade management options cover stop-loss and take-profit settings and closing positions when the signal weakens or reverses.

The author presents the system as an educational prototype and discusses Strategy Tester runs on silver using different timeframes. The supplied text gives no numerical performance results; its conclusion says the tests were not good and calls for further experimentation with timeframes, RSI periods, and the difference between the indicators. It also cites concerns about RSI's intraday and forex performance, so the crossover idea should be treated as an unvalidated strategy rather than evidence of a trading edge.

Key ideas

• A fast RSI crossing a slow RSI supplies the Expert Advisor's entry signal across selected symbols.
• The system includes multi-symbol and single-symbol modes, plus optional trading-session restrictions.
• Stop-loss, take-profit, and signal-weakening rules provide configurable trade management.
• The described Strategy Tester results are characterized as poor, without numerical evidence in the supplied text.
• The article recommends further testing of timeframe and RSI parameter choices.
