Closing Open Trading Positions by Symbol or Magic Number

Article MQL5 code base
Read the original

Summary

This document outlines three position-closing functions for trading automation. One closes all open positions for a specified symbol, using the current chart symbol when no symbol is supplied. A second closes positions across all symbols after gathering the distinct symbols that have open trades, which avoids processing the same symbol repeatedly. A third limits closures to positions bearing a specified magic number, supporting setups where multiple expert advisors manage trades in the same account.

The material is a concise feature description rather than a strategy or performance analysis. It explains how the functions scope the positions they target, but provides no implementation details, execution behavior, or testing evidence. Users would need to account for platform and broker behavior when applying these operations.

Key ideas

  • A symbol-specific function can close positions for a chosen symbol or the current chart symbol.
  • A close-all function gathers unique symbols before processing their open positions.
  • A magic-number filter can target positions associated with a particular expert advisor.
  • The document gives no evidence about execution reliability or testing outcomes.
