Parabolic

Parabolic(Initialization, Acceleration factor, Maximum Acc. Factor) as Array

Parabolic returns an array containing the Wilder's Parabolic SAR indicator.

This function has three parameters:

Initialization    Enter the initialization factor, typically 0.02.

Acceleration factor    Enter the acceleration factor, typically 0.02.

Maximum Acc. Factor    Enter the maximum acceleration factor, typically 0.4.

Example:

' This is a system based on the Parabolic SAR
Sub Main()
  SAR = Parabolic(0.02, 0.02, 0.4)
  For CurrentBar = BeginBar + 1 to EndBar
    SAR1 = SAR(CurrentBar)
    SAR2 = SAR(CurrentBar - 1)
    AOsc = GetValue("Aroon Up", CurrentBar) - GetValue("Aroon Down", CurrentBar)
    P1 = Close(CurrentBar)
    P2 = Close(CurrentBar - 1)

    If (P1 > SAR1) and (P2 < SAR2) then
      If AOsc > 50 then Buy(CurrentBar)
    End If
    If (P1 < SAR1) and (P2 > SAR2) then
      If AOsc <= 0 then Sell(CurrentBar)
    End If
  Next
End Sub

Initialization	Enter the initialization factor, typically 0.02.
Acceleration factor	Enter the acceleration factor, typically 0.02.
Maximum Acc. Factor	Enter the maximum acceleration factor, typically 0.4.
