What to know
- Use MQL5 source for MT5 instead of copying MT4 code directly.
- Compile in MetaEditor and test on a demo chart.
- Confirm buffer plots, indexing direction, and chart timeframe behavior.
- Review whether your symbol uses tick volume or exchange volume.
MT5 differences
MQL5 has a more structured indicator API than MQL4. Buffer setup, handles, and calculation loops often need platform-specific attention.
Best candidates
Levels, channels, ATR overlays, swing labels, and simple moving average tools are strong first candidates for MT5 examples.
Testing approach
Check historical bars, live bar updates, and multiple timeframes before assuming a script is ready for daily use.
How to use this page well
The quickest way to get value from a platform page is to decide whether you are here for installation, source code, or workflow guidance. Those are related, but they are not the same job. Download-oriented pages help you get something working. Source-oriented pages help you inspect and adapt logic. Workflow pages help you decide whether a tool deserves a place on the chart at all. Keeping those jobs separate makes the site much easier to navigate.
That separation is especially important when you are moving between platforms. A trader who comes in through MetaTrader may still end up on a product page, a source page, a guide, or a glossary entry before the question is fully answered. This hub exists to make that path shorter and less confusing.
