Building MQL5 Expert Advisors with EA Tree’s Visual Logic Builder

Summary

The article introduces EA Tree, a graphical tool that creates MQL5 Expert Advisors by connecting typed boxes for indicators, functions, values, conditions, trade actions, and money management. It explains how outputs connect to compatible inputs and how logic boxes represent comparisons, conjunctions, disjunctions, and crossover conditions. The generated MQL5 file is then compiled in MetaEditor and can be optimized in the MetaTrader Strategy Tester.

A worked example specifies long and short entries using MACD crossovers confirmed by the direction of a 20-period exponential moving average. It uses the opposite entry conditions to close existing positions and leaves money management at its default. The walkthrough illustrates how to translate rule-based conditions into a visual tree, rather than evaluating whether the strategy is profitable. It gives no test results, execution assumptions, or risk analysis, and the article’s claims about development speed and code correctness are not supported by comparative evidence.

Key ideas

• EA Tree represents an Expert Advisor as connected boxes with typed inputs and outputs.
• Logic boxes combine comparisons and indicator values into trade-entry and exit conditions.
• The example uses MACD crossovers and moving-average direction to define long and short rules.
• Generated MQL5 code must be compiled and can then be optimized in the Strategy Tester.
• The tutorial explains construction but provides no evidence of strategy performance.
