Buy on thursday, sell on friday

[BenLePen]

Hello,

how can I enter a position on thursday and sell on friday? I tried

def wd(daten):
    x = daten.dt.dayofweek
    return(x)

    def init(self):
        self.wday = self.I(wd, zeitreihe_input['Close'])

    def next(self):
        if (not self.position and self.wday == 3):
            self.buy(size=einsatz)
        elif (self.position.is_long and self.wday == 4):
            self.position.close()

But this does not work.

OK, solved it. I had to create a new column first:

zeitreihe_input["day_of_week"] = zeitreihe_input.index.dayofweek

...
