MQL5 Expert Advisor Automation, Strategy Testing, and Market Data
Summary
This overview of a trading automation section introduces the MQL5 concepts used to build Expert Advisors. It begins with instrument specifications and trading account settings, then covers built-in functions, data structures, robot events, and the Strategy Tester. The tester is presented as a tool for evaluating and optimizing trading strategies, with debugging options that include visual runs over bars or ticks, modeled or real ticks, and nonvisual tests.
The overview also introduces Depth of Market and its programming interface, along with symbol management in MetaTrader 5. MQL5 programs can inspect symbol properties and add or remove broker-provided symbols from Market Watch. The platform also supports custom symbols whose properties and price history can be loaded from external sources or generated through formulas and programs. This is a chapter outline rather than a worked strategy or empirical study; it does not report test results or explain the limitations of particular data models or testing settings.
Key ideas
- Reliable Expert Advisors depend on instrument specifications and trading-account settings.
- The Strategy Tester supports visual and nonvisual testing, including different tick-data modes.
- MetaTrader 5 exposes symbol properties and Market Watch controls through the MQL5 API.
- Custom symbols can use imported histories or data generated through formulas and programs.
- The overview discusses Depth of Market but gives no detailed implementation or strategy results.
