Filtering MT4 Drawdown by Expert Advisor and Symbol

Summary

This brief note explains that an MT4 drawdown calculation can be scoped by magic number and trading symbol. Those filters make the reported drawdown apply to trades associated with a particular Expert Advisor identifier and instrument, rather than necessarily representing the whole account. The note also says that removing both filters from the code changes the calculation to include overall account drawdown.

The document offers a practical distinction between strategy-level and account-level risk measurement, but does not describe the underlying drawdown formula, whether open positions are included, or how equity and balance are handled. It provides no examples, test results, or implementation detail beyond the filter behavior. As a result, users should confirm the calculation’s scope and treatment of positions before relying on its output for risk limits or comparisons. The key lesson is that drawdown figures are only comparable when their symbol and strategy filters are understood.

Key ideas

• An MT4 drawdown calculation may be filtered by magic number and symbol.
• Those filters scope the result to trades associated with a particular identifier and instrument.
• Removing both filters makes the calculation include overall account drawdown.
• The note does not specify the formula or whether open positions affect the reported value.
