Building an MQL5 Library to Manage Pending Orders

Summary

This article develops an MQL5 library and example interface for managing pending orders. It describes functions for placing, modifying, deleting, filtering, and sorting orders, including operations scoped by symbol or other order categories. The library relies on standard MQL5 trade requests and results, tracks order counts and volumes, checks trading permissions, and reuses error-handling functions from a companion library.

The article also explains how to package the functions as an EX5 library and demonstrate their use through a graphical panel. Retry handling is included for failed server requests, with pauses between attempts, and logging reports order parameters and server outcomes for debugging. The material is a software implementation tutorial rather than a trading strategy or empirical study. It offers no evidence that pending-order management improves execution or profitability, and practical behavior depends on broker responses, permissions, and the calling program.

Key ideas

• The library provides reusable functions for placing, modifying, deleting, filtering, and sorting pending orders.
• Order operations use standard MQL5 request and result structures to communicate with the trade server.
• Order counts and volumes can be tracked across account, symbol, and magic-number categories.
• Permission checks, error handling, retry delays, and detailed logs support operational management.
• The accompanying interface demonstrates the library; the article does not evaluate trading performance.
