metatrader seems to automatically delete old log files from .../experts/logs/, leaving only the last five trading days. is it possible to configure it to not delete the old log files? i realise that i could write a script to rename or move the old log files, but it would be easier to just set an option in the terminal. i have checked under Tools->Options but there does not seem to be anything appropriate.
What if there's no check-box to keep the Log files longer?
Perhaps writing an EA or script which reads and write the log-file to another file could solve your problem perhaps.
