Thank you for your help and sorry for these much replies... the fully code looks now like this: Looks like your connection to Backtrader Community was lost, please wait while we try to reconnect. While pandas only supports flat columns, the Table also provides nested columns, thus it can represent more data than a DataFrame, so a full conversion is not always possible.
