Quick tips
- Make sure you’re using the correct platform version: MT4 tools will not work on MT5, and vice versa.
- If you receive .mq4 or .mq5 source files, open them in MetaEditor and press F7 to compile, then restart the terminal.
- If the tool doesn’t appear in Navigator, confirm the file is in the right folder and restart the platform.
- Some products include presets (.set) or templates; follow the product’s notes on where to place them.
