Bruce, Can you convert this code to where it will work in SF?  Here is a screen shot link and the Metatrader code below:

Well could someone tell me if we could use ZZTop, ZZTop(1), and ZZTop(2) and the same for the bottom and then just plot out the horizontal line with the price on that line?  Would SF RC be able to understand the defining points that we would want in this or is that something that Kuff would have to look at to see if it is even possible in the API.  Also is there a downloadable copy of the RC API somewhere so as to be able to print out the api into a booklet for referance?

Bruce I get these errors when adding the code:
ZZP not declaired. Lines 14, 15,18, 24, 25

Here is the code copied after I pasted what you gave me.

Any idea what I did wrong?
