Jayson,
I do not like the idea to save the code just for the code and create
a formula quite strange in application [imagine the user who will
trade it !!]
Since Peak() and related functions do not accept variable percentage,
we just donīt use variable percentage and thatīs all. The use of
Lastvalue(C) *does not introduce* variable perc in Peak() function
and can not be considered as a solution, partial or final.
The only way is to follow the analytic Peak() code procedure, see if
it is possible to introduce variable perc and use the probable result
as a new function.
It is not always easy. I did it for the RSI of MACD before the built-
in RSIA because I knew all the analytic steps. I could not say
something similar for Peak() function. I exposed an idea in my
Variable % peak just to have a first taste of this variable % and its
probable application. Of course, this sample is far from the analytic
Peak() procedure.
Solving a code trouble is not the same with writing a correct code,
ie a code to answer the question.
May be, someday, built-in Peak() accepts variable %. Before this, Peak
() function should work with negative arrays, it is more important
IMO. [You can not apply Peak() to an MACD() array for example].

PS I donīt remember if Peak() was included in the vote list...
