Do you want :
[a]. Strategy Tester to run on the background or [b]. when current testing finished, to start another testing with same EA with different setting, or [c]. when current testing finished, start another testing with different EA ?
I want b and c. I need to keep my machine busy when it is done. SO when a particular EA H1 is done I want to maybe sart same (or diffrent) EA on M30. I want some automation in the tester... period
Sorry for being unclear.
The command line parameters allow starting the terminal with a custom configuration file (ex. terminal.exe /config:c:\myconfiguration.ini). And there is a part in the configuration file which allows setting test/optimization parameters for the strategy tester - [Tester].
Also there are functions in MQL5 that allow working with optimization results "on-the-fly", they might be also useful for you.
