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

  Have you tried it, because it works fine for me…

  What doesn’t work…?

  When I tried it yesterday during regular trading hours, it didn’t work. Now that I’ve tried it when the market is closed, it mostly works. This happens sometimes to me with other indicators as well. I wonder why…

  But there are many false positives. Take a look at the screenshots here where NLB and NRB = 2; there are many examples of the displayed fractal not being the local min or max of the candle range (t-2, t+2, so in total 5 candles). Do you know why this happens?

  Hi,

  Try this one… (small addition error)

  x-Bar Fractals

  Once NLB=2 //Number Left Bars Once NRB=2 //Numer Right Bars TB=NLB+NRB //TotalBars fp=NRB //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=2 //Number Left Bars Once NRB=2 //Numer Right Bars     TB=NLB+NRB //TotalBars fp=NRB //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
