  On a 1 hour chart, can someone help with s code that at 9am in today’s trading session, looks at yesterday’s trading session and draws horizontal lines on highest high and lowest low between 10am and 12 noon. It should keep those lines across all of today’s trading session and only resets and does same again once today’s session is over and chart gets to tomorrow’s session at 9am

  Hi. Test this code:

  sessionStart = 090000 // 09:00:00 rangeStart = 100000 // 10:00:00 rangeEnd = 120000 // 12:00:00 if opentime=sessionStart then bar=barindex endif once maxref=high once minref=low if opentime>=rangeStart and opentime[1]<rangeStart then lastmaxref=maxref lastminref=minref maxref=high minref=low elsif opentime>=rangeStart and opentime<=rangeEnd then maxref=max(high,maxref) minref=min(minref,low) endif if islastbarupdate then drawsegment(bar,lastmaxref,barindex+5,lastmaxref)coloured("cyan") drawsegment(bar,lastminref,barindex+5,lastminref)coloured("red") endif return minref coloured("red",75), maxref coloured("cyan",75)

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

  sessionStart = 090000  // 09:00:00 rangeStart   = 100000  // 10:00:00 rangeEnd     = 120000  // 12:00:00   if opentime=sessionStart then    bar=barindex endif   once maxref=high once minref=low   if opentime>=rangeStart and opentime[1]<rangeStart then    lastmaxref=maxref    lastminref=minref    maxref=high    minref=low elsif opentime>=rangeStart and opentime<=rangeEnd then    maxref=max(high,maxref)    minref=min(minref,low) endif   if islastbarupdate then    drawsegment(bar,lastmaxref,barindex+5,lastmaxref)coloured("cyan")    drawsegment(bar,lastminref,barindex+5,lastminref)coloured("red") endif   return minref coloured("red",75), maxref coloured("cyan",75)

  Thank you Ivan. It works.

  How do I now add to exactly same i.e. highest high and lowest low between 12noon and 2pm and between 2pm and 4pm?

  In other words when I run the code, every morning at 9am, it draws 3 pairs of high and lows, 1 pair 10 to 12 of previous session, 1 pair between 12 and 2 previous session and 1 pair between 2 and 4pm of last session.

  tnx in advnce

  Hi. You introduce as much intervals as you want. Here one more (Just do the same)

  // Horarios configurables sessionStart = 090000 // 09:00:00 rangeStart = 100000 // 10:00:00 rangeEnd = 120000 // 12:00:00 rangeStart1 = 220000 rangeEnd1 = 020000 if opentime=sessionStart then bar=barindex endif once maxref=high once minref=low once maxref1=high once minref1=low if opentime>=rangeStart and opentime[1]<rangeStart then lastmaxref=maxref lastminref=minref maxref=high minref=low elsif opentime>=rangeStart and opentime<=rangeEnd then maxref=max(high,maxref) minref=min(minref,low) endif if opentime>=rangeStart1 and opentime[1]<rangeStart1 then lastmaxref1=maxref1 lastminref1=minref1 maxref1=high minref1=low elsif opentime>=rangeStart1 and opentime<=rangeEnd1 then maxref1=max(high,maxref1) minref1=min(minref1,low) endif if islastbarupdate then drawsegment(bar,lastmaxref,barindex+5,lastmaxref)coloured("cyan") drawsegment(bar,lastminref,barindex+5,lastminref)coloured("red") drawsegment(bar,lastmaxref1,barindex+5,lastmaxref1)coloured("blue") drawsegment(bar,lastminref1,barindex+5,lastminref1)coloured("fuchsia") endif return minref1 coloured("fuchsia",75), maxref1 coloured("blue",75),minref coloured("red",75), maxref coloured("cyan",75)
