Yes use the Object functions,  you can draw Horizontal, Vertical, Trend lines and channels, Fibs, etc.

Thanks for your prompt answer.

I tried ti implement it but it seems to not work.

I add it on my code :

<SNIP>

then in the start() session :

objTrendLine("Test", 1357492150, 3700,1357492854, 3731.5,0,1,0,STYLE_SOLID, true);

Could you pelase give me an exemple ?

Thanks

Please edit your post . . . 


Please use this to post code . . . it makes it easier to read.

Your code looks OK  . . .  the datetime of time1 and time2 are only 704 seconds apart,  if you create that Onject on any timeframe shorter than M15 there is a good chance that both times will be on the same bar and in that case you won't see the line.

Your function call may be wrong,  you seem to have a colour of  0

It works now. Thanks.

I used : DateTime = D'04.01.2013 18:24:27' (it's easier to locate on graph) and now it appears on my graph!

I tried to make a Griphical Analyse with program.

How do we delete the line on graph ?

Use ObjectDelete() . . .

 

Please edit the code in your earlier post.  Use the SRC button . . .

Thanks RaptorUK.

For the moment, I am only testing to draw line on graph.

Once the line is draw, is it possible to compare the value of Close and the position of the line dawn ? (upper or down the line ?)

For exemple :

if(Close[0]>Line) then....

or

if(Close[0]<Line) then....

I draw a Line on "EURUSD" and i would like to compare the Close[0] position with the Line.
