Symbol with Ma as NPS

[bigtee]

I have been using the SymbolCompareasNPS efs to plot other symbols as indicators. However I would like to add a moving average to it.

Searching around I have found the RelativeStrengthratiowithMA is virtually identical to what I want. The only problem with using that one is that I don't want to compare the symbol with the symbol in the Price window. Thus it would seem that all I have to do is remove the divide by function and tweak the code that does the Title and Cursor label.

However, I can't seem to get it to work.

If anyone can point me in the right direction it would be most appreciated.

Here is the forum with the starting code

Thanks,

bigtee,

I'm working on this now... what did you want the default MA Length to be?

20 periods is fine

This seems to do the trick. Enjoy!

JayF, thanks. It works

Now, a couple questions.

1. Why did you choose to eliminate the Average subroutine and just calculate
directly?

2. Just for grins and my learning experience, tell me in words what I would
do to add a second Ma?

3. A suggestion for you and the EFS Learning Center. How about putting a
lesson in there on how to add an Ma to another indicator? Much like this
one. It seems it requires changing to an array and doing other things that
are not quite so simple. If the lesson were heavily commented it might help
a lot of folks.
