Si, serve una versione modifica appositamente per le candele HA, eccola:

Multiplier = 3
Periods    = 10
/ candele HA
ONCE xOpen = open
xClose     = (open + high + low + close) / 4
IF BarIndex > 1 THEN
   xOpen   = (xOpen[1] + xClose[1]) / 2
ENDIF
xLow       = min(low,min(xClose,xOpen))
xHigh      = max(high,max(xClose,xOpen))
MedianHA   = (xHigh + xLow) / 2
//
IF BarIndex > Max(Periods,Multiplier) THEN
   MyATR         = AverageTrueRange[Periods](xClose) * Multiplier
   BasicUPPER    = MedianHA + MyATR
   BasicLOWER    = MedianHA - MyATR
   IF (BasicUPPER < FinalUPPER[1]) OR (xClose[1] > FinalUPPER[1]) THEN
      FinalUPPER = BasicUPPER
   ENDIF
   IF (BasicLOWER > FinalLOWER[1]) OR (xClose[1] < FinalLOWER[1]) THEN
      FinalLOWER = BasicLOWER
   ENDIF
   IF (ST[1] = FinalUPPER[1]) AND (xClose <= FinalUPPER) THEN
      ST = FinalUPPER
   ELSE
      IF (ST[1] = FinalUPPER[1]) AND (xClose > FinalUPPER) THEN
         ST = FinalLOWER
      ELSE
         IF (ST[1] = FinalLOWER[1]) AND (xClose >= FinalLOWER) THEN
            ST = FinalLOWER
         ELSE
            IF (ST[1] = FinalLOWER[1]) AND (xClose < FinalLOWER) THEN
               ST = FinalUPPER
            ENDIF
         ENDIF
      ENDIF
   ENDIF
ENDIF
RETURN ST AS "Super Trend HA"
