AttributeError: 'Plot_OldSync' object has no attribute 'mpyplot'
Planet Winter last edited by Planet Winter
I am new to backtrader and the forum. After looking at several platforms I came back to backtester.
I am not a professional programmer. However I attempted to import csv data and plot it which fails with AttributeError: 'Plot_OldSync' object has no attribute 'mpyplot'
Can someone point me to the right direction? pudb debugging didn't get me further.
EDIT: setting todate and fromdate to the same values for both data, does not help.
Thanks in advance,

I am running this in an up to date virtualenv. Backtrace:

try to update to a recent version of backtrader or try to add a strategy.
The plot method will exit without a strategy before creating the mpyplot object, which is being tried to be shown in the show method later

Thanks! I did a pip install --upgrade backtrader in my virtualenv which helped! I was sure I already did that but was apparently not true. This now gives me an IndexError I will look into that.
Notwithstanding that it is unclear if you added an strategy, the addition of the data feeds is missing the specifics about
Cryptocurrency traders tend apparently to look at timeframes smaller than
1-daywhich is the default when adding a timeframe.
