Buy order not creating a position ?

[valentin-fngr]

Expected Behavior

Hi, here is the simplest strategy code you can ever imagine :

class newStrategy(Strategy):
        

    def next(self):
        if not self.position:
            self.buy()
            assert self.position

I am not passing the assert !
Meaning that self.buy() is not creating a position. Am I not understanding something ?
