Multiple Timeframes and data alignment
-
Hi,
When using multiple Timeframes, the documentation mentiones that
The datas must be properly date-time aligned for the platform to make any sense out of them
For the convenience of future use I'm resampling data files (from here) to daily, weekly and monthly data files. I.e. each bar of the resampled data file will represent a day, week or month.
Days and months will naturally align, weeks and months will not. What is the meaning of "properly date-time aligned"?
The data that I'm using has 6 trading days per week. Below are some snippets of resampled weekly and monthly data. Will this be fine as far as backtrader is concerned?
Weekly:

Oh, never mind. This is a non-isue so long as all Timeframes align to the fastest one.
