PIVOT lines drawn into the future (v11 only)

  Recently PRT introduced, along with version 11, new options to use graphic drawing tools to plot into future bars, a long awaited feature.

  The easiest way is to simply add an offset to BarIndex, such as BarIndex + 5.

  There are time, though, when you don’t know the correct value of that BarIndex number. Here comes in handy the new keyword DateToBarIndex(MyDate), to be used with graphic drawing instructions. PRT’s engine will calculate the correct BarIndex number to be used. It’s very useful if you need to draw segments from, say, the beginning of the day through the end of the day. Some instruments trade 24 hours, other less. You don’t have to care about this, the new keyword will!

  This is an example on how to use it. It plots Pivot lines at the beginning of each day, through the end of the day:

  DEFPARAM DrawOnLastBarOnly = true // IF OpenDay <> OpenDay[1] THEN // Pips = 20 * pipsize StartBar = BarIndex // // PredeEndDated PRT calculation (H+L+C)/3 Pivt = (DHigh(1) + DLow(1) + DClose(1))/3 // - Pivot Res3 = DHigh(1)+(2*(Pivt-DLow(1))) //Res3 Res2 = Pivt+(DHigh(1)-DLow(1)) //Res2 Res1 = (2*Pivt) - DLow(1) //Res1 Sup1 = (2*Pivt) - DHigh(1) //Sup1 Sup2 = Pivt-(DHigh(1)-DLow(1)) //Sup2 Sup3 = DLow(1)-(2*(DHigh(1)-Pivt)) //Sup3 // MyYear = OpenYear MyMonth = OpenMonth MyDay = OpenDay // pack Year, Month and Day into YYYYMMDD MyDate = (MyYear * 10000000000) + (MyMonth * 100000000) + (MyDay * 1000000) // add HHMMSS EndDate = MyDate + (23 * 10000) + (0 * 100) + 0 ENDIF // plot Pivot at (unknown)barindex of date YYYYMMMDDHHMMSS DRAWSEGMENT(StartBar,Pivt,DateToBarIndex(EndDate),Pivt) coloured(0,128,0,255) STYLE(dottedline,1) DRAWTEXT("Pvt #Pivt#",DateToBarIndex(EndDate),Pivt+Pips) coloured(0,128,0,255) // plot Resistance levels DRAWSEGMENT(StartBar,Res1,DateToBarIndex(EndDate),Res1) coloured(255,0,0,255) STYLE(dottedline,1) DRAWTEXT("R1 #Res1#",DateToBarIndex(EndDate),Res1+Pips) coloured(255,0,0,255) DRAWSEGMENT(StartBar,Res2,DateToBarIndex(EndDate),Res2) coloured(0,0,255,255) STYLE(dottedline,1) DRAWTEXT("R2 #Res2#",DateToBarIndex(EndDate),Res2+Pips) coloured(0,0,255,255) DRAWSEGMENT(StartBar,Res3,DateToBarIndex(EndDate),Res3) coloured(0,128,128,255) STYLE(dottedline,1) DRAWTEXT("R3 #Res3#",DateToBarIndex(EndDate),Res3+Pips) coloured(0,128,128,255) // plot Support levels DRAWSEGMENT(StartBar,Sup1,DateToBarIndex(EndDate),Sup1) coloured(255,0,0,64) STYLE(dottedline,1) DRAWTEXT("S1 #Sup1#",DateToBarIndex(EndDate),Sup1+Pips) coloured(255,0,0,64) DRAWSEGMENT(StartBar,Sup2,DateToBarIndex(EndDate),Sup2) coloured(0,0,255,64) STYLE(dottedline,1) DRAWTEXT("S2 #Sup2#",DateToBarIndex(EndDate),Sup2+Pips) coloured(0,0,255,64) DRAWSEGMENT(StartBar,Sup3,DateToBarIndex(EndDate),Sup3) coloured(0,128,128,64) STYLE(dottedline,1) DRAWTEXT("S3 #Sup3#",DateToBarIndex(EndDate),Sup3+Pips) coloured(0,128,128,64) RETURN

  Example to pack single data into a YYYYMMDDHHMMSS date:

  YYYY = 2020 MM = 03 DD = 30 HH = 11 MM = 26 SS = 15 YYYY * 10000000000 = 20200000000000 + MM * 100000000 = 0300000000 + DD * 1000000 = 30000000 + HH * 10000 = 110000 + MM * 100 = 2600 + SS * 1 = 15 = -------------- 20200330112615 YYYYMMDDHHMMSS

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

  YYYY = 2020 MM   = 03 DD   = 30 HH   = 11 MM   = 26 SS   = 15   YYYY * 10000000000 = 20200000000000 + MM   *   100000000 =     0300000000 + DD   *     1000000 =       30000000 + HH   *       10000 =         110000 + MM   *         100 =           2600 + SS   *           1 =             15 =                      --------------                      20200330112615                      YYYYMMDDHHMMSS
