Error on calling 'OnBarUpdate'

[stockgoblin]

Hi,

So I figured out:

DrawRay("Line1" + Time, false, 0, High[0], 1, High[Math.Min(CurrentBar, 1)], Color.SkyBlue, DashStyle.Dot, 1);

thanks to this common error explained here:

http://www.ninjatrader-support2.com/...ead.php?t=3170

but I'd like to go a step back and highlight the line that was drawn before the first one.

essentially:

DrawRay("PreviousLine", false, 1, High[1], 2, High[2], Color.Yellow, DashStyle.Dot, 2);

so isn't that:

DrawRay("PreviousLine", false, 1, High[Math.Min(CurrentBar, 1)], 2, High[Math.Min(CurrentBar, 2)], Color.Yellow, DashStyle.Dot, 2);

computer doesn't like that...

what don't I understand about Math.Min or this concept of the bar doesn't exist yet. I got the first one.

1. Your link is broken,
2. If you want to access a bar 2 bars ago, then you need to escape 2 bars at the start of OBU. You need the statement:

if (CurrentBar < 2) return;

Ha! had if (CurrentBar < 1)

thanks .
