Hi,
I'm developing a simple indicator that draws a line where prior day's close price is on 1 min chart. See my code below:
1. For some reason, Closes[1][1] in Draw() method is not working. Nothing shows up on chart. But if I change it to a specific value, for example:
Draw.HorizontalLine(this, "Prior Close", 40, Brushes.Red);
This specific value shows up. So it must be my additional data series not working. Would you please tell me how to make it work?
2. I need it to draw just one line everytime a daily bar is closed. It looks like my code will draw a lot of lines on chart everytime primary series bar is updated. Also, when a daily bar is closed, prior close price gets updated, the old line needs to be deleted. How can I make this work?
Thank you very much for your help!

//Disable this property if your indicator requires custom values that cumulate with each new market data event.
//See Help Guide for additional information.
IsSuspendedWhileInactive = true;
AddPlot(Brushes.CornflowerBlue, "Prior Close");
}
else if (State == State.Configure)
{
AddDataSeries(Data.BarsPeriodType.Day, 1);
}
}
protected override void OnBarUpdate()

return;
