As far as I know, the PET-D indicator is not very well known publically. After all, ‘someone’ (the creator) is hyping it to shreads and selling it for few hundred dollars. EDIT: Apparently $2,995.

I looked it up a few months ago, and someone said that the PET-D behaves very similar to a comparing price to a simple exponential average of 15 periods (http://www.protraderstrategies.com/steven-primo-dyamic-duo/). Not exactly of course, but close enough. If you combine that with whether the bar is red/green and it’s body/range ratio, then maybe you can create something similar.

I googled it and it seems like the MT4 code for PET-D could be found in the file for this strategy. It would need to be converted for PRT: https://www.forexstrategiesresources.com/scalping-system-iv/452-pet-d-scalping-system/

EDIT: Took a look at the code. Apparently this is what you get for that price:

This indicator paints candlesticks in green when the current Close is above a exponential moving average of 8 periods and red if it is below it.
This can be coded the same way within the new version of prorealtime and the custom candlesticks construction, do you still want it to be coded?

And they sell it 3000 USD !!! It’s madness !

It is already “decoded”. The whole indicator is basically:

PETD=1
If close<Exponentialaverage[8] then
PETD=-1
Endif
Return PETD

Or am I wrong?
