There are no mind readers here, so you may want to put full error message.
Also use backticks to post code blocks, this is written on the every top of the page.

@Abhishek-Agrawal said in TypeError:

cerebro = bt.Cerebro

You need brackets on bt.Cerebro

bt.Cerebro()

Abhishek Agrawal

Thanks a lot for the reply man it helped.
@run-out there's one another problem- The code is not ending anywhere. It is just running

run-out

Print your log out to terminal for OHLCV and see what's happening.
