Oscillator VORTEX difference displays as a histogram the difference between +VI and -VI of indicator Vortex.
For it to operate correctly, the availability of indicator Vortex is not required - the indicator calculates it independently.
It has one input parameter:
- Period - Vortex indicator calculation period.
Calculation:
Diff = +VI - (-VI)
where:
+VI = 100 * svip / satr, -VI = 100 * svim / satr
where:
svip = SMA(iVIP, Period) svim = SMA(iVIM, Period) satr = SMA(ATR, Period) iVIP = Abs(High - PrevLow) iVIM = Abs(Low - PrevHigh)
