Convert X-bars Fractals Indicator (Serhii Ivanenko, MQL5) to ProRealTime

  Fractals are used to identify market structure — a moment t where:

  Down fractal:
  Low(t) <= Lowest(t-a, t+b)
  for the minimum in domain [t-a, t+b]

  Up fractal:
  High(t) >= Highest(t-a, t+b)
  for the maximum in domain [t-a, t+b]

  Example:
  If lookback = 20 and a = b = 3

  Assume that at time t = i = 10 (bar index, where 0 is current, 1 is previous, n is nth bar, etc.):
  Lowest(10-3, 10+3) → Lowest(7 to 13) = Low(10)
  Then t = 10 is a down fractal.

  Reference:
  Here is the code of the existing indicator (X-bars Fractals from Serhii Ivanenko) that would be great to convert for ProRealTime users:

  Thank you !

  Hi,

  Try this one…

  x-Bar Fractals

  Once NLB=5 //Number Left Bars Once NRB=5 //Numer Right Bars TB=NLB+NRB //TotalBars fp=NRB+1 //fp=fractal point If High[fp]=Highest[TB+1](High) then DrawArrowUp(BarIndex-fp,High[fp]) Coloured("Blue") EndIf If Low[fp]=Lowest[TB+1](Low) then DrawArrowDown(BarIndex-fp,Low[fp]) Coloured("Green") endIf Return

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

  Once NLB=5 //Number Left Bars Once NRB=5 //Numer Right Bars     TB=NLB+NRB //TotalBars fp=NRB+1 //fp=fractal point   If High[fp]=Highest[TB+1](High) then DrawArrowUp(BarIndex-fp,High[fp]) Coloured("Blue") EndIf   If Low[fp]=Lowest[TB+1](Low) then DrawArrowDown(BarIndex-fp,Low[fp]) Coloured("Green") endIf   Return
