Even though I only can use a cut and paste approach (with some logic) to formulae building I pretty much end up with what I need, but not this time. I want to plot the 5 period %R of a 10 period EMA. The basic idea comes from a Trend Analyzing Tool created by J Kennedy which describes just part of the tool as: .

Start with 5-period exponential moving average. This is a blue line. Then take 5-period %R, 10-period %R, and 15-period %R of the blue line and place in a single window.

The problem is that the Williams%R is not a plot based indicator and therefore I cannot drag and drop it on the EMA. I would really appreciate if someone could point me in the right direction as to what I should be looking at to solve this problem

Brilliant, thanks johnl, from your code it took me just 30 mins to do all the variations and save as a template. What's more important is that I studied how you did it so learned a lot for future reference.

For anyone who is interested the complete description of the indicator can be found at http://www.elliottwave.com/freeupdates/archives.

I'm not a big fan of Elliott waves but I've found this tool useful to give me an idea if the market is in corrective or impulsive mode and how strong the trend is.
