Building Multi-Symbol Balance and Drawdown Charts in MetaTrader 5
Summary
This article describes an MQL5 application for visualizing combined trading results across multiple symbols. It modifies the standard MACD Sample expert advisor to test a list of instruments, records deal history after a test, and reads that data to draw a multi-symbol balance curve and deposit drawdown chart. The graphical interface includes controls, status information, and an update button; a related version refreshes the graphs during live trading or visualized tests.
The workflow covers parsing a comma-separated symbol list, checking symbols against the broker's available instruments, and initializing a strategy instance for each accepted symbol. It also explains extracting per-symbol balance series from deal records for charting. The author explicitly cautions that the demonstration's multi-symbol strategy structure is inaccurate: test results can vary with the symbol selected in the tester, so it is intended to illustrate visualization rather than provide a reliable trading system. The article is most useful for reporting and platform development, not as evidence of strategy performance.
Key ideas
- The application charts aggregate balance and drawdown data for a multi-symbol test.
- It saves deal history after testing and reconstructs per-symbol balance series for display.
- A user-provided symbol list is parsed and checked against the broker's available instruments.
- A graphical interface can refresh results after testing or during trading and visualized tests.
- The example's multi-symbol strategy structure is acknowledged as inaccurate and unsuitable for reliable performance conclusions.
