Basic price pattern detection
|SYNTAX||Peak(ARRAY, change, n = 1)|
|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.|
