Hello i’m sorry to tell you that code didn’t work it did print the three ranges but they all have the same number and the number is 195.7 I also looked at the Look Back of 10 ranges and manually did the equation and I didn’t get anywhere near that number and I also shifted the 10 ranges back one more just a double check has the way that I did the equations and the output of those equations

They also is a screenshot if you look at the bottom right that’s this code that you’ve helped me with top right is my previous code we’ve standard deviations not this more complex but better equation
