Following a request by @Bard at https://www.prorealcode.com/prorealtime-indicators/pivot-support-resistance-zones/, I made this variation of the same indicator, with EMA bands replacing S&R Pivot segments:

// Pivot Support & Resistance Bands
//
// https://www.prorealcode.com/prorealtime-indicators/pivot-support-resistance-zones/
//
DEFPARAM CalculateOnLastBars = 1000
//p    = 2                            //2  periods
//Type = 1                            //1 = Ema
PivotBAR     = 2                      //2  bars AFTER  pivot
LookBack     = 4                      //4  bars BEFORE pivot
BarLookBack  = PivotBAR + 1
IF low[PivotBAR] < lowest[LookBack](low)[BarLookBack] THEN
   IF low[PivotBAR] = lowest[BarLookBack](low) THEN
      //MySupport     = BarIndex - PivotBAR
      SupportPrice  = low[PivotBAR]
   ENDIF
ENDIF
IF high[PivotBAR] > highest[LookBack](high)[BarLookBack] THEN
   IF high[PivotBAR]  = highest[BarLookBack](high) THEN
      //MyResistance    = BarIndex - PivotBAR
      ResistancePrice = high[PivotBAR]//high[BarIndex - MyResistance]
   ENDIF
ENDIF
EmaResistance  = average[p,Type](ResistancePrice)
EmaSupport     = average[p,Type](SupportPrice)
MidLine        = EmaSupport + ((EmaResistance - EmaSupport) / 2)
//DRAWSEGMENT(MyResistance,ResistancePrice,BarIndex,ResistancePrice) COLOURED(255,0,0,255)
//DRAWSEGMENT(MySupport,SupportPrice,BarIndex,SupportPrice) COLOURED(0,128,0,255)
RETURN EmaResistance COLOURED(255,0,0,255) AS "EmaResistance",EmaSupport COLOURED(0,128,0,255) AS "EmaSupport",MidLine coloured(0,0,0,32) AS "MidLine"

It returns the two bands (Support & Resistance), plus the mean line.
