High/Low/Close previous day with time

YES, thanks!

I am also trying to add one horizontal line showing open price NY-midnight. This line I only want to be printed for the current day, no history needed.

And one more little help would be appreciated, I would like one horizantal line across the daily chart showing previos weeks high and low.

Thank you!

There you go:

DEFPARAM DrawOnLastBarOnly = True
ONCE NYtime = 060000
ONCE CurO   = open
ONCE CurH   = high
ONCE PrevH  = high
ONCE CurL   = low
ONCE PrevL  = low
ONCE CurHw  = high
ONCE CurLw  = low
ONCE PrevHw = high
ONCE PrevLw = low
ONCE OdW    = 0
IF OpenDayOfWeek < OpenDayOfWeek[1] THEN
   OdW      = 1
ENDIF
IF (OpenTime = NYtime) OR ((OpenTime > NYtime) AND (OpenTime[1] < NyTime)) THEN
   IF OdW = 1 THEN
      PrevHw= CurHw
      PrevLw= CurLw
      CurHw = high
      CurLw = low
      OdW   = 0
   ENDIF
   CurO     = open
   PrevH    = CurH
   PrevL    = CurL
   CurH     = high
   CurL     = low
   Start    = BarIndex
ENDIF
CurH        = max(high,CurH)
CurL        = min(low,CurL)
CurHw       = max(high,CurHw)
CurLw       = min(low,CurLw)
DrawSegment(Start,CurO,BarIndex,CurO) coloured("Green") style(Line,2)
RETURN PrevH coloured("Blue") style(Line,2) AS "Previous DAY high",PrevL coloured("Red") Style(Line,2) AS "Previous DAY low",PrevHw coloured("Gold") style(Line,2) AS "Previous WEEK high",PrevLw coloured("Fuchsia") Style(Line,2) AS "Previous WEEK low"
