hi! Please write here your issue.

[ronytesler]

this is my code:

data15 = bt.feeds.GenericCSVData(dataname='BTCUSDT-15m-2022-01-01.csv',
dtformat=lambda x: datetime.utcfromtimestamp(int(x)/1000))

and this is from csvgeneric.py:

dt = datetime.strptime(dtfield, dtformat)
    else:
        dt = self._dtconvert(dtfield)

if self.p.timeframe >= TimeFrame.Days:
    # check if the expected end of session is larger than parsed
    if self._tzinput:
        dtin = self._tzinput.localize(dt)  # pytz compatible-ized
    else:
        dtin = dt

    dtnum = date2num(dtin)  # utc'ize

    dteos = datetime.combine(dt.date(), self.p.sessionend)
    dteosnum = self.date2num(dteos)  # utc'ize

    if dteosnum > dtnum:
        self.lines.datetime[0] = dteosnum

I see that for each candle, dt, dtin and dtnum are correct. dteosnum is the same all the time, and larger than dtnum, so dteosnum is the one assigned to the next candle (self.lines.datetime[0]).

So all candles get the same time.

Hi! I think you are already solved your problem))
But if you need some info, i use the following:

def next(self):
    """Приход нового бара тикера"""
    for data in self.datas:  # Пробегаемся по всем запрошенным тикерам
        if self.p.symbols == '' or data._name in self.p.symbols:  # Если торгуем все тикеры или данный тикер

            ticker = data._name
            _date = bt.num2date(data.datetime[0])

so, _date is different for tickers.
