  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)
