What is the alternative for bt.analyzers.BasicTradeStats?

backtrader14

I need some basic stat report for my sample strategy and while searching came across bt.analyzers.BasicTradeStats . It was implemented in 2017 and I think its removed or renamed from future versions.

AttributeError: module 'backtrader.analyzers' has no attribute 'BasicTradeStats'

I went and searched the docs for BasicTradeStats which does not exist there. What is the better alternative for bt.analyzers.BasicTradeStats?

If you are looking for trade stats, than you may want to use TradeAnalyzer or Closed trade list (including MFE/MAE) analyzer.

@backtrader14, or anyone else who stumbles across this thread:
you can still get this working if you take the BasicTradeStats analyzer class and import it as a custom analyzer of your own.

To do so, follow the steps here to make modular code for backtrader, substituting "analyzers" for "indicators" where necessary: https://backtest-rookies.com/2017/11/01/backtrader-making-modular-code/

Under your extensions folder, create the analyzers.py file (along with init file), and paste the content from the analyzer found here: https://raw.githubusercontent.com/rich-oregan/backtrader/master/backtrader/analyzers/basictradestats.py

Finally, in your code, make sure you have something like the following lines:

# import the file at the top of your code where "BasicTradeStats" is the name of the class
from extensions.analyzers import BasicTradeStats
# add the strategy to cerebro
cerebro.addanalyzer(BasicTradeStats, _name="BasicTradeStats")


 opt_runs = cerebro.run(maxcpus=1, runonce=False)
  for run in opt_runs:
     for strategy in run:
# finally, this will print the analyzer
print(strategy.analyzers.BasicTradeStats2.print())

Works great!
