how to add a trendline with arrow on chart?

 

hello
I am considering Metaquote as my new trading/charting application and cannot seem to be able to draw a trendline with an arrow at one end as per the image enclosed (not using mql4). I went through the code base and could not find any object with that property, any thought?
I am not looking draw a segment and add a wingdings next to it.
thxs for your help
regards

 
No, there is not such graph object as line with arrow at the and. I can only suggest to compose something similar by adding triangle to line.
Or you can use a graph editor to create screen shot.
