Hi
Thank you very much for the tip. It turned out to be fruitful.

Hi there ,

I am sorry, I feel other already had this issue and it was solved .
if I have a text file with the following data structure,shown on attached picture do I need to create my own class of data feeder or use generic csvdata feeder of the backtester ?
I thank you in advance for your help and tips .

It's my mistake. I read it wrong. Thank you for directing me in right way .

why copying this script i receive these messages ?

I just install Backtrader and started to get acquainted with the Quickstart but I see that it needs to be updated because even the
included code examples are still based on yahoo. What other data providers can I use for so that not to get the exceptions and errors in these examples ? is among them Alpha vantage or other ones ?I'm sorry if I did not find a thread related to it.
