This is a stock screener that will fetch stocks that have made a new Fractal (calculated upon the last “p” period = 10 periods by default) in the last 5 days (“lookback” variable that can be modified at line 6 of the below code).

Some Fractals indicators can be downloaded too in the Library:

• original Bill Williams Fractals indicator for Prorelatime version 10.2
• Zig-zag indicator made of Fractals points for Prorealtime version 10.3
• Another version of the Zig-Zag indicator with 2 sets of zigzag points (PRT v10.3 only)

The Fractals code here do not respect completely the Bill Williams original description (FYI).

This screener has been coded by request.

if high[p] >= highest[2*p+1](high) then
 fractalH = 1

if low[p] <= lowest[2*p+1](low)  then

newhigh = summation[lookback](fractalH=1 and fractalH[1]=0)=1
newlow = summation[lookback](fractalL=-1 and fractalL[1]=0)=1
