Plotting Trend lines forward

[Alexander <alexander@xxxxxxxxxxxxxxxxx>]

Good morning!

Is it possible to plot a trend line forward beyond the last bar on the chart
(to the right), like using Plot[-1](Value,"MyValue")? I tried TL_New[-1](...)
and TL_New(date, time, StartVal, date[-1], time, EndVal) but they don't work.
And, I can't use TL_SetExtRight since the plotted forward value is not the same
as the value on the last bar of the chart. 

Any suggestions are greatly appreciated.

Thanks!
