description	Use when compiling MQL5 experts, indicators, scripts, or include-dependent code in this workspace from the terminal. Follow the local MetaEditor command pattern and always inspect the compilation log after running it.

Compile MQL5

Use this skill when compiling .mq5 files in this repository.

Command

Use MetaEditor64.exe from the local MetaTrader installation.

Example command:

& 'C:\Program Files\MetaTrader 5\MetaEditor64.exe' /compile:'C:\Users\<user>\AppData\Roaming\MetaQuotes\Terminal\<terminal-id>\MQL5\Experts\codex\FVG.mq5' /log:'C:\Users\<user>\AppData\Roaming\MetaQuotes\Terminal\<terminal-id>\MQL5\Logs\codex-fvg-compile.log'

Adjust the compiled file and log path to the target being worked on.

Log Review

Always read the log after compiling.

For the current EA example, the log is:

C:\Users\<user>\AppData\Roaming\MetaQuotes\Terminal\<terminal-id>\MQL5\Logs\codex-fvg-compile.log

Do not assume compilation succeeded just because the command returned exit code 0. Check the log and report:

1. Number of errors.
2. Number of warnings.
3. Important file paths mentioned by the compiler.
4. Whether the expected .ex5 file was produced or updated.
