Well, Amibroker has drawing "layers" already for manual chart mark-
ups. Why doesn't Tomasz just provide a way to programatically get to
them? That way, there would be no programming (e.g., looping)
required to update them on the user's part. Once drawn, Amibroker
would take care of any refreshes needed when the lines come into the
viewable area.

While if the line would stay displayed like a study, it would require
no maintenance. All I would need to do is calculate the last leg. far
more efficient...
