Thanks Smon. Just to clarify, as far as I see, resampling happens in your python script ['split_file' function] not in c file, am i correct?

Unfortunately, CSV to History script only converts csv format to t6 format as it is, without any resampling.

I was hoping to make Zorro resample external price data during runtime; similar to how Zorro resamples t6 files with BarPeriod when price data added as an asset.

Cheers.
