[amibroker] peak/trough question

[James <jamesmemphis@xxxxxxxxx>]

What does change mean in the syntax of park and trough? It is not explained in the reference quide at all.

 

PEAK

− peak

 

SYNTAX peak(ARRAY, change, n = 1)

RETURNS ARRAY

FUNCTION Gives the value of ARRAY n−th peak(s) ago. This uses the Zig Zag function (see Zig Zag) to

determine the peaks. n =1 would return the value of the most recent peak. n =2 would return

the value of the 2nd most recent peak. Caveat: this function is based on Zig−Zag indicator

and may look into the future.

EXAMPLE peak(close,5,1)
