The date of the first bar should be the first timestamp of the 2020 file minus the number of bars for the lookback period, with considering gaps and weekends.

No, I don't receive that 047 warning anymore (I forgot to mention this, sorry). The issue is that my Zorro versions return different date outputs with the same code and the same .t6 files. You can see this on my last screenshot. Code function run() { History = ".t6"; BarPeriod = 1; StartDate = 20200102; if(Bar > 0) { printf("\nDate: %s \| Price: %.5f",strdate(YMDHMS,ldate(UTC,0)), priceClose()); quit(); } } Last edited by Grant; 03/18/22 12:10.

Zorro 2.44 (which was installed in a formal 2.40 directory) returns 'Date 200102 07:02:00..' Zorro 2.46 (and probably Zorro 2.44 in a fresh directory as well) returns 'Date 200102 07:01:00..'. I'm wondering what's causing this.
