Hello Roozbeh,

Thank you for your kind words...I tried very hard to make the instructions clear. I am sorry that they have failed you in this instance : )

As you know, since you have built out your own R/S model, the calculation is very involved. So it is very difficult for me to evaluate what might be wrong with your calculation based on the limited amount of information you provided. My advice would be to download the spreadsheet that is associated with this article and to work through our calculation as compared with mine. I have a hunch that your difficulty may be in the very final step where slope is calculated based on the number of ranges you have selected.

Yours, in service,

Jason
