multiple stocks order

[Sam]

Hi, I wanted to buy two stocks under dfferent condistions. The thing is data0 works , data1 doesn't , thanks for your time!!!

    def next(self):
        for i, d in enumerate(self.datas):
            if i==0:
               if self.leida0.today > 0 and self.leida0.lastday<0:

                   o1 = self.buy(data=d)
            if i==1:
               if  self.leida1.today > 0 and self.leida1.lastday<0:

                    o2 = self.buy(data=d)

stock1 has buy signal (the green triangle)
but stock 2 doesn't

[Sam]

OK I realized, actually the transaction of stock2 completed, Why is there no buy signal --- the green triangle ?

Try to use addobservermulti to have BuySell observer applied to several data feeds.
