Hi there,
If you just need to see how to extend your datas past ohlc adj close and volume, using pandas dataframe, I could help you with this.
If you like I could just do that part of your backtrader file for you? And then answer any questions you have by video?
I charge $50 / hour but if your file is well organized, it should take long.
Why don't we say a flat $30 USD to extend your pandas datalines in backtrader and a short call to answer any questions you have.
Cheers,
Neil
