drawline question

[balancenv]

(This might be a very simple question but I did search the forum...)

I have a very simple indicator, finding certain pattern of 4 points P1 to P4, then do a simple drawline from P1's high to P4's low (P4L), since P1i and P4i are forward style index (i.e., # of bars since bar 0) so I use CurrentBar-P1i to convert it to 'barsago' style. But this is not the issue.

DrawLine("", CurrentBar - P1i, High[CurrentBar - P1i], CurrentBar - P4i, P4L, Color.GreenYellow);


The problem is, even though there're more than 50 patterns found (I know since I dumped iall of them to output window) only the last line is shown on the chart.

So how would one keep ALL the drawlines fixed on the chart?

balancenv, so you would be using a unique tag id for each object you try to create? From your code sample that does not seem to be the case - http://www.ninjatrader.com/support/f...ead.php?t=3419

Yes, this does the trick.
Thank you very much!
