Re: [amibroker] peak/trough question

[Keith McCombs <kmccombs@xxxxxxxxxxxx>]

Notice help says that Peak() is based on Zig().  Zig uses 'change' where change is a percent.  For more info see help for Zig().

Notice that help for both Peak() and Zig() have links to many formulas.  Not only are formulas given in these links, but but many of the formulas are discussed at length, including warnings about how Zig() looks into the future and may not be appropriate for trading.

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)
