Before you dive in
- 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 is more structured than MQL4, which is great until you paste in old code and wonder why nothing behaves. Buffers, handles, and calculation loops need more care here.
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 you let yourself believe a script is ready for daily use.
How to get something useful out of this page
The quickest way to get value from a platform page is to be honest about what you need. Are you here to install something, study the source, or figure out whether a tool belongs on your chart at all? Those jobs overlap, but they are not the same thing. Download pages help you get up and running. Source pages help you inspect and adapt the logic. Workflow pages help you decide whether the tool is even worth your screen space.
That separation matters even more when you are moving between platforms. A trader who starts on MetaTrader may still need a product page, a guide, or a glossary entry before the question is really answered. The goal here is to make that path shorter and a little less messy.
