Thank you ! The problem was half solved with your solution, it gave me 23:59:00 at each line instead of the real time, the solution was to add a :
timeframe=bt.TimeFrame.Minutes in the GenericCSVData parameters

Thanks again !

Hi, when an order is initiated in the backtest, does backtrader use the next data lines OHLCV to know if the order could have passed ? How does it know ?

Update : The problem with the comma was an Excel thing, when I copy pasted it on an Text Editor there were commas at each line.

After that, I got an IndexError: array assignment index out of range, which was solved by adding more data, thanks to this thread : https://community.backtrader.com/topic/407/indexerror-array-assignment-index-out-of-range/3

My last problem is that I don't know how to show Hours-Minutes-Seconds when I launch the script, my log function is :

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

Backtrader shows me :
2019-06-30, Close, 295.65
2019-06-30, Close, 295.65
2019-06-30, Close, 295.85
But how can I have H-M-S too in the log function ?

@backtrader Yes that is the problem, I don't understand why the quote is here. I just followed the documentation of GenericCSVData, do you have an idea about why ?

Hi, I have a problem creating my own DataFeed

I used GenericCSVData to use my CSV file on Backtrader, but I get this error :

ValueError: time data '"2019-06-30T15-10-00' does not match format '%Y-%m-%dT%H-%M-%S'

Which doesn't make sense because it seems to be right.
I succeeded to make it working with a CSV years-months-day only, but not with hours-minutes-seconds, I don't understand why ? I think the problem might be this " which is near the 2019 in the error message, but I don't know how to erase it.

Here is the code :

modpath = os.path.dirname(os.path.abspath(sys.argv[0]))
datapath = os.path.join(modpath, 'backtrader/datas/yhoo.csv')
# Create a Data Feed
data = btfeed.GenericCSVData(
dataname=datapath,

nullvalue=0.0,

dtformat=('%Y-%m-%d'),
tmformat=('%H-%M-%S'),

datetime=0,
time=1,
open=2,
high=3,
low=4,
close=5,
volume=6,
openinterest=-1

)

Here is my CSV : https://ibb.co/sF47WV4

And here is the full error I get :
