How can I draw parallel extended lines with NinjaScript?

I've checked the NT forum and not much help was found there.

Thanks

You can either use the :

DrawTrendChannel("tag1", true, 10, Low[10], 0, High[0], 10, High[10] + 5 * TickSize);

Or you calculate the Angle yourself and draw individual lines that are parallel

Thanks for the suggestion.
I would rather draw the lines myself but the problem is calculating the angle.

I tried using the DrawTrendChannel method and the issue is that method does not allow the lines to be colored differently.
I also tried the DrawAndrewsPitchfork and the line color can be changed but only as a group not individually (Top/bottom)

Drawing angles seems to not work the ways I have tried.
I have no issue drawing a trend line from tops or from bottoms but the angle calculating is not something I have been successful at accomplishing.

Here is what I tried but the lines are not parallel.

Code

DrawRay("rayLow", true, CurrentBar-prevlobar, prevlo, CurrentBar-lastlobar, lastlo, Color.Green, DashStyle, 4);

DrawRay("rayHigh", true, CurrentBar-prevhibar, prevhi, CurrentBar-lastlobar,(lastlo+(prevhi-prevlo)), Color.Red, DashStyle, 4);

Thank you for your input.

Thanks for the link I will watch it when I get in this afternoon.

None of this is critical.
The line colors are simply cosmetic and the TrendChannel or Andrews is sufficient.

However, when I tried to do it myself I found I did not understand the concept and that is always a challenge.
So I will learn the concept and be able to do it.

I figured it was a little complicated since everyone that asked on the NT forum was given vague answers and told it was an advanced concept. That type of response always makes me want to find out more. Kind of like saying "this is too difficult for you to understand" Hmm.

Thanks again.
