thanks it gives me Invalid switch error
Also instead of using a command line batch file, just update the shortcut file of the Windows menu to add the parameter.

Is it possible to load specific profile before MT5 starts
If i have Profile A B C, and profile A was active before i shut down MT5
now next time i want to open MT5 but with Profile B, is there any method such as any file i can create and upon clicking it recognize which profile to open
