MQL4 Trade Manager: Free MT4 EA Download & Source Code

Overview

MQL4 Trade Manager replicates the native MQL5 OnTrade function within the MQL4 environment, which lacks a built-in event for position changes. By monitoring the order pool during each price tick, the code detects when trades are opened or closed and triggers a user-defined function. This allows for cleaner code structure when building complex management tools or logging systems. The repository provides a library file and a basic sample script but does not include automated entry or exit strategies.
