Thanks man!
Maybe I should read all the docs first and then the repository.

WOW it works. Thank you a lot!!

I try to read to code in the repository but is quite complex.
So I don't have to pass
self.datas[0].datetime.date(0)
But what are the differences from self.data?

Self.datas is created in the Cerebro class as his attribute with an empty list right?
Instead self.data are what returns backtrader.feeds.GenericCSVData.
Sorry for asking but I still miss the various structures because there are a lot of passages.
Anyway thanks again!!

Hi,
I' am just following the guide on the docs. But I load 15 minutes bars dataset. Hope I passed the right parameters with GenericCSVData.
Anyway I would like to print also the time (H:M:S) when the backtest starts. So I think I have to change something on dt variabile, but I cannot understand all the process and specifically the structure of self.datas.

class TestStrategy(bt.Strategy):

    def log(self, txt, dt=None):
        dt = dt or self.datas[0].datetime.date(0)
        print('%s, %s' % (dt.isoformat(), txt))

And that's the code for adding data feed:

data = bt.feeds.GenericCSVData(
        dataname = datapath,
        dtformat=('%Y-%m-%d %H:%M:%S'), # O H L C V 
        openinterest=-1,
        timeframe= bt.TimeFrame.Minutes,
        compression= 1
        )
        )
    cerebro.adddata(data)

Finally the structure of csv data passed with datapath is this:

It accepts the datafeed but I would like to see the complete date when it starts. Mainly because I would like to understand how data are passed with generic csv.

Thank you!
