Execution gives many 'Canceled/Margin/Rejected' orders
-
When executing an optimization I'm getting many 'Canceled/Margin/Rejected' orders. There must be something wrong with my strategy but I can't figure out what it is.
Also the output that I'm expecting is around 10% and it should look like this:
But right now I'm getting a maximum of 7.7% and the output looks too uniform which makes me think something is wrong:

I forgot to copy the code:

@quake004 said in Execution gives many 'Canceled/Margin/Rejected' orders:
if self.crossover > 0: self.log(f'BUY CREATE {self.dataclose[0]:.2f}') self.order = self.buy() elif self.crossover < 0: self.log(f'SELL CREATE {self.dataclose[0]:.2f}')Did you forget to copy the last line where the sell order is created or not? Other than that, I can't quickly spot something wrong with your code.
