I cannot get this line plot and show in databox

[randomwalker]

the following is the codes trying to plot a horizontal line of yesterday VWAP on today's intraday chart. However, it just cannot get plot on the chart, any idea?

if (Bars.FirstBarOfSession )
{

if (Time[0].DayOfWeek == DayOfWeek.Monday)
timeOfInterest = new DateTime(Time[0].Year, Time[0].Month, Time[0].Day - 3, 16, 30, 0);
else
timeOfInterest = new DateTime(Time[0].Year, Time[0].Month, Time[0].Day - 1, 16, 30, 0);
}
barsAgo = GetBar(timeOfInterest) ;


Plot0.Set(VWAP().VWAPLine[barsAgo]);

Any errors in the log tab? Do you include a check for enough CurrentBars at the OnBarUpdate() start? Otherwise you run into issues reaching back at the start of your charts as there're no bars back then to calc for.

The message from log tab is that:" Error calling the 'OnBarUpdat' method for indicator on bar 78 :year, month and day parameters describle an unrepresentable datetime" And I run another indicator "SampleGetBar" downloaded from this support forum and see the same message from logtab. What should I do?

You would need to print out associated values to debug where the issues stems from in your code at this time, I believe you would see this for example for an 'irregular' session day as last Monday (Memorial Day in the US) for example.

I have code that successfully draws horizontal lines to my indicator panel in "maximum" display mode (right click the verticle axis) but I do not see the lines in a data box. How do I get these horizontal lines to display in a data box?

[NinjaTrader_Bertrand]

That would unfortunately not be possible, only plots could be displayed in the data box.

More control over the databox contents is on our feedback list for the next major NT version update, I've added your request in.

Thanks,
