Can I use the DrawLine function

[kaywai]

to update a drawn line as new bars are formed?

Yes Kay, just use the same tag Id then in your call to update a drawing object - http://www.ninjatrader-support2.com/...ead.php?t=3419

Bertrand, Under the DrawLine syntax, I have to indicate an int[endBarsAgo]...how do i circumvent that? I tried placing a 0 but that stops the line at the current bar.

2) assuming i could circumvent the requirement i mentioned above, can i set a condition so that it will stop the line from extending? if so, how do i do that?

You can't circumvent it, as it's a needed paramter to tell the DrawLine method where your line ends...NinjaTrader 7 would allow of plotting into the future...

To stop the line from extending at some point you would need to ensure your endBarsAgo variable it not changing as your current bar progresses.
