There are a number of examples of drawing a line between two points in the archives but I suspect
this is not what you want. You say you want to draw a line between two points but I'm assuming that
the first point is known (time and value) and the second point is a projection to some time and
value in the future.
The essential elements required for such a line are, one, a starting time and value, and two, an
increment or decrement per bar. If you know these things then the code and maths is basic stuff.
The line might be coded something like this.
ValueWhen(1,"unique event","starting value") + ("calculated increment")*BarsSince("unique event");
