HI

am looking for help on regards the DRAWRECTANGLE function

Would like to paint a rectangle between two prices. e.g. 1 and 2.

and the width of the rectangle should be from OPEN to CLose (or 5 bars into the future)

Somehow I cant get this managed with Barindex and co,

Can someone help me ?

Legend
A rectangle is plotted according to two coordinates:
- price (from price 1 to price 2)
- bars (from bar 1 to bar 2), which can also be in the future, if you like.
The line width is specified by a numeric constant, not a price:
```
DEFPARAM DrawOnLastBarOnly = True
ONCE Price1 = 0
ONCE Price2 = 0
ONCE Bar1   = 0
ONCE Bar2   = 0
IF (Time >= 090000) AND (Time <= 210000) THEN
   IF Time = 090000 THEN
      Price1 = open
      Bar1   = BarIndex
   ENDIF
   Price2 = close
   Bar2   = BarIndex
ENDIF
IF Price1 <> 0 THEN
   DrawRectangle(Bar1,Price1,Bar2,Price2) coloured("Grey",25) BorderColor("Fuchsia",255) style(Line,3)
ENDIF
RETURN
```

Thanks.. i solved it like this

defparam DRAWONLASTBARONLY = true

mintimeFrame = 9

if GetTimeFrame/60 >= minTimeFrame then

maxCheck = 50
i = 0
lastOuterBar = -1

lastLow = low[maxcheck]
lastHigh = high[maxcheck]

for i = maxCheck-1 downto 0
if open[i] >= lastHigh or open[i] =< lastLow or close[i] >= lastHigh or close[i] =< lastLow then
lastLow = low[i]
lastHigh = high[i]
lastOuterBar = i
endif
next

if lastOuterBar > 0 then

x1 = barindex
y1 = high[lastOuterBar] //high[barindex+1]
x2 = barindex-lastOuterBar
y2 = low[lastOuterBar]//low[barindex+1]
DRAWRECTANGLE(x1, y1, x2,y2) coloured(255,155,0)FILLCOLOR(255,255,230)
endif
endif

RETURN
