See clone code. Essentiallly I am importing pandas and numpy and issuing unstack on a dataframe resulted from functions found on these two libraries and comparing it with the results from using unstack on a history dataframe. As a reference, in my eyes, the arrange or dataframe resulted from pandas/numpy is dimensionally the same as the dataframe resulted from history. So I am not sure why, after unstack, the shifting on the arrangement of colums/indexes on one output differs from the other.
Specifically, I was expecting self.u (unstacked dataframe from pandas/numpy) shifting of its indexes/columns to "look" the same as self.uncz (unstacked dataframe from history/close price). Am I erroneous on seeking a similarity on the output between these two "unstacked" dataframes if they have been created from different mechanisms?
Any insights/comments will be greatly appreciated.
Thanks,

Not sure why I can't add the clone of the code and/or backtest

Hi Eduardo,
The DataFrame returned from the `unstack` call has its columns alphabetically sorted. See the attached backtest for reference, where the column named 'one' has been updated to 'zone'.
Best,

Thanks. I was not aware of unstack reordering alphabetically. Thanks so much!
