MQL5 Code Guides for MetaTrader 5

Choose a guide for the job

• EA examples: inspect the actual signal, order and risk logic. Check broker symbol names, point sizes, trading sessions and netting or hedging assumptions.
• Indicator guides: trace handles, buffers and bar indexing. An indicator display is not an executable strategy or a verified trading result.
• Tutorials: isolate one API or development task. Some examples are function fragments and need a surrounding program before compilation.
• Strategy guides: define a test protocol, including costs and out-of-sample data. A testing guide does not supply evidence of a profitable backtest.
