{quote} Dear tkhan011, The second one is based of a ZigZag indicator. The 'eint Depth' = 'Extension Depth' and is based on deviation. So if you search to read about how the zigzag works you will understand the 2nd indi. The configuration looks standard. Kind Regards, Tzamo

{quote} Dear tkhan011, You are welcome. Another way to proceed for the first file is to open the attached files in the metaeditor and find where the functions are used. Then with the help of the help file search you can work out what each thing does. For example you can see that the 'nslow' is used in the '2 / (nslow+1)' to give a new value labeled 'slowSC'. Then you can follow where that new value is used. I would use a pen and paper to write out with arrows to help understand what each of those parameters controls. Kind Regards, Tzamo
