Thank you very much!
I checked the file and indeed, there was an error. This occurred due to the conversion from CSV to .t6, as I hadn't placed the separator ("+%Y/%m/%d,%H:%M%:S,f3,f1,f2,f4,f6") in %H%M%S.
Therefore, all the candles (within one hour) had the same hour and minute. Thank you very much!
