hi to all,

i am new here and start to learn programming to make my own indicators.

I hope someone can help me with my actual problem.
- i search the highest high and the lowest low on the 15 minutes chart between 8 and 9 o’clock
- the problem is that i get all the highs and lows from every candle in this timerange
thanks for the help in advance

kind regards
```
defparam calculateonlastbars = 100

if time > 080000 and time < 090000 then
HighestH = high //max(high,high)
LowestL = low //min(low,low)

//UpperRange = HighestH < HighestH[1] and HighestH > HighestH[2]
//BottomRange = LowestL > LowestL[1] and LowestL < LowestL[2]
endif

//if currentdayofweek = 1 or 2 or 3 or 4 or 5 then

drawray(barindex-1,HighestH,HighestH,HighestH) coloured(0,200,0) STYLE(line,2)

drawray(barindex-1,LowestL,LowestL,LowestL) coloured(200,0,0) STYLE(line,2)

//endif

return
```

At line 3 you should use >= and <=.

Lines 4-5 must be replaced by:
```
HighestH = max(high,HighestH)
LowestL  = min(low,LowestL)
```
but you also need to reset them each day, at the beginning of the code, at line 2:
```
If IntraDayBarIndex = 0 then
   HighestH = 0
   LowestL  = 999999
endif
```

You need to use as first or second line:
```
Defparam DrawOnLastBarOnly = true
```
