CMB Derivative Oscillator

[Anson]

Constance Brown's Derivative Oscillator (with a very slight mod)

I have managed to plot this (to my best ability) in Metastock using very simple coding but stumble once again when it comes to efs versions.

Could an efs expert like Alex, Jason or others kindly help out?

The original uses a normal RSI while I prefer to use a 14-period RSI which uses the HLC/3 value. Hence the "Typical" in the RSI here.
The original also uses a 9 period SMA but I prefer it to be 8 period.

==================
Step 1 is a 5 period EMA of the Typical (value) RSI.

Step 2 is a 3 period EMA of Step 1.

Step 3 is an 8 period SMA (simple) of Step2.

Finally, the result of Step 2 - Step 3 is plotted as a histogram.
===================

The Metastock code:

RSIA:=RSI(Typical(),14) ;
Step1:=Mov(RSIA,5,E);
Step2:=Mov(Step1,3,E);
Step3:=Mov(Step2,8,S);
(Step2-Step3);

Picture attached of it. (on Metastock)

With the exception of the very last step, ie the subtraction in the returned value, which has to be written using the Editor, the rest of the efs can be written using the Formula Wizard (see the attached efs)

Alexis,

Thanks for the help!

I did attempt to use the Formula Wizard but it didnt work out. I'm a real failure at it.

You can see I did try my best on Metastock and I think it turned out ok. I'll take a look at your code and try to learn something from it. :P

Many thanks!

As this efs uses the Studies on Studies feature of the Formula Wizard you may want to see this thread on the topic
