Greetings all,
Could you please help understand this function, especially, the 3rd argument - Number?
Is that a built-in AmiBroker function? I am still using version 6.20.1 and I don't see it in the Help file.

Yes it is....me testing Beta 6.28.0...Stable as of now....Got intrigued by this new function !
@Lennon I see that this (undocumented) function is actually available in the code editor also in previous versions (I tested it in an old 5.70 version). Seems not so new! 
I suppose the last parameter must be a period (similar to correlation). But I will wait to see any official (or at least beta) documentation before using it.

Hey @beppe,
I imagine this function has to do with figuring out +ve/-ve divergence when two arrays are compared with each other and like you mentioned the 3rd argument probably stipulates the look back period.
Cheers!
P.S. My journey with AB started with v6.18

That function is at least 14 years old as it is present also on AmiBroker 4.60 of 2004 (see picture below). How many more years it has been part? I don't know.
On the old list T.J. confirmed years ago that it is not a function for public use.

Possibly it is a function made on single request (by a friend) or own use...

This function is private. Third argument is not period. I am sorry, but since this function is not public, I can't provide more details, but there is nothing magical in it.
