Noob python coder and can't understand how to set up and store elements in a rolling window
Not sure what I am doing wrong but when I run this code I end up with the error message and I can't figure out how to fix the rolling windows. There is a lot more in this code but the error is located here:
Runtime Error: Trying to dynamically access a method that does not exist throws a TypeError exception. To prevent the exception, ensure each parameter type matches those required by the 'NoneType'>) method. Please check out the API documentation.
import numpy as np
#in Initialize
self.legnth = 5
self.SetWarmUp(timedelta(self.legnth))
self.arrary1 = RollingWindow[float](self.legnth)
self.arrary2 = RollingWindow[float](self.legnth)
#in function
if condition:
self.arrary1.Add(x)
else
self.arrary1.Add(y)
if not self.arrary1.IsReady:
return
element2 = np.sum(self.arrary1)
self.arrary2.Add(element2)
if not self.arrary2.IsReady
return

Hi Michaelpet17,
Try replacing
with
See the attached backtest for reference. If that doesn't fix the issue, share more of the algorithm so we can reproduce the error.
Best,

I love you more than you know Derek! That didn't fix the issue but I made a new basic function to sum my array as below and then it worked perfectly. I never would have guessed that's where my issue was so thank you very much I greatly appreciate it!
