Dimitris, thanks for that.
It also assumes the last bar of the 2 drawn lines to be the end of the
chart. I cannot get it to use the actual last bar of the drawn lines. OK if
the lines are right extended to, or past, the last bar. The prices are ok
for the ends, just put onto the wrong bar.
I have tried different methods to get the right end bar number for the lines
to no avail.
Cheers,
Graham

Graham,
thank you for sharing this.
You should add, in the beginning, a SetBarsRequired(10000,10000); to
help if QuickAFL is enabled.
One more note [for my codes also] :
We both suppose the line is drawn from left to right !
If you draw f1 or f2 from right to left, there is no result.
We should add some min(t1,t2) to avoid this.
