How could I adapt this Normalized Standard Deviation...

[buzzhorton]

How could I adapt this to get the Normalized Accumulation/Distribution or Momentum(12)?

I wrote my own version of THE NORMALIZER.

This looks interesting.

Thanking You in Advance.

Why was this moved?

I put it where it says to ask questions about EFS.

Hello Avery,

The formula code you posted is from the EFS Library. This is the appropriate forum for discussing library formulas.

Ok.. thanks.

Hello Avery,

Sorry for the delay on this one. Here's what you can do. In the pop/unshift routine, notice the source used for this array is close(0)? I think all you would need to do is create a series for the momentum study etc and replace close(0) with the .getValue(0) of the chosen series. You could also rewrite the study and use an sma() series in place of the aValue array. That way you could pass in the momentum series as the source. Give that a shot and let me know if you need any help.
