NT 6.5.9 DrawLine out of range error

[astrolobe]

When using the following statement:
DrawLine("tag1",10, ChannelPoints[2].Price, 1, ChannelPoints[0].Price, Color.DarkTurquoise);
I get the following error when trying to use the DrawLine command in my NinjaScript Strategy:
DrawLine: startBarsAgo out of valid range 0 through 6, was 10. source = NinjaTrader.Core

The problem is that I have over 30 bars in my chart, so trying to go too far back is not the problem. The result of the CurrentBar statement just before the DrawLine command returns 32.

Thanks for the quick response.
When I check the CurrentBar before the DrawLine statement, the value is 32. I am am only trying to start my line from 10 bars back...there has to be another explanation, besides too few bars on the chart.

thanks.

I suggest debugging your NinjaScript as per here: http://www.ninjatrader-support.com/v...ead.php?t=3418

I have plenty of Print statements around the DrawLine statement. The issue is very simple...I have over 30 bars on my chart, as per the printout of the CurrentBar value at the time of trying the DrawLine. I am only trying to start the line from 10 bars back.
The NT error is telling me the startBarsAgo value must be between 0 and 6. Implying that there are no more than seven bars on the chart. However, I can see 32 bars on my chart, and CurrentBar is confirming that.

I suggest starting from scratch by a simple as possible indicator to understand where your logic breaks. If you got a simple DrawLine statements working you could add your custom logic step by step to understand which step causes the failure.
