I use that in my run function, just some rough thing, not very sophisticated.
But not possible with Z12

if(day(0) != day(1) and Live) //save trd file once per day
file_copy("C:\\Users\\Administrator\\Desktop\\TRD\\MyStrategy\\MyStrategy.trd", "C:\\Users\\Administrator\\Desktop\\Zorro\\Data\\MyStrategy.trd");


adding a date in cmd is awkward, just use some simple freeware / opensource tool.

The above folder is then synced to my clouddrive.
