Hi

Is there any code available for drawing a simple horizontal line across a chart, based upon the close of a candle at a set time each day? For example, a horizontal line at the close of the 1pm H1 candle on the Dow? The line would need to ‘expire’ (delete itself) when the next days line is drawn.

Many thanks

I think this code should work correctly for this purpose:
```
defparam drawonlastbaronly=true

if time=130000 then 
value=close
endif

drawhline(value)

return
```

Hi

When I try to plot this indicator on a separate pane it plots a 0, when plotted in main pane nothing appears. Any suggestions? Thank you.

Because the separate don’t adapt automatically its scale with plotted object like horizontal line. If you change the last line of the code with:
```
return value
```
it should adapt itself automatically.

Why it doesn’t show on the main pane? .. be sure the instrument has quote at time it saves the value (1 pm in the code).

Thanks Nicolas. That works, just as the original one works.

I wish to plot the Open, High and Low of the first 30 minutes of trading and want it to be displayed on a 5 or 10 min chart. Is this possible?

Also, I wish to plot yesterday’s Open, High and Low on continuous data ie will have to be able to specify open hours and should also be able to display in various time frames. Is this possible?

I realize the requests are much more than the original topic – would it be preferable to start these requests as separate ?

Thank you.

Yes you can store a time in a variable, it’s nothing more than a number 🙂
```
defparam drawonlastbaronly=true

mytime = 150000

if time=mytime then 
 value=close
endif

drawhline(value)

return
```

hi @nicolas,

thanks for getting back.. what i meant was.. adding two lines on the chart one at 130000 and one at 150000. and a way to switch those times (add on the variables- like tick or untick) so we can either see two lines on the chart or we can untick to see one?!?! tried below but its a big failure!!
```
defparam drawonlastbaronly=true
mytime = 150000 
mytime1 = 130000
 
if time=mytime and mytime1 then
value=close
endif
drawhline(value)

return
```

Ok, here is the modified code for that purpose:(draw0 and draw1 boolean variables been introduced)
```
defparam drawonlastbaronly=true
mytime0 = 150000 
draw0 = 1 //1=true, 0=false
mytime1 = 130000
draw1 = 0 //1=true, 0=false
 
if time=mytime0 then
 value0=close
endif
if draw0 then 
 drawhline(value0)
endif

if time=mytime1 then
 value1=close
endif
if draw1 then 
 drawhline(value1)
endif

return
```

```
draw0 = 1 //1=true, 0=false
```
That means if you set “draw0” to 1, it will plot the line. Set to 0, it will plot nothing. Same for “draw1” to draw or not the second line.
