Problem with too many closing trades.

[Jeffrey C F Wong]

Hi everyone, I have the following codes where crossover_exit should only close when there is an existing long order and crossunder_exit should close when there is a ongoing short order. But my results shows that it is closes a trade whenever there is a crossover_exit or crossunder_exit condition, resulting in too many closes. It'd be great if someone can shine some light on this. Thank you in advance.

            if not self.position:
                if self.crossover:                  
                    self.buy()
            
                if self.crossunder:        
                    self.sell()
            
            if self.position.size!=0:                        
                if self.position is self.buy and self.crossover_exit:
                    self.close()            
               
                if self.position is self.sell and self.crossunder_exit:
                    self.close()
