multiseries CurrentBars always == -1 for added data

[volkie]

I have a very simple indicator where I add 1 Day data to grab the X day highs/lows easily.

I am using it in a historical data chart. It never calls OnBarUpdate with BarsInProgress == 1, only 0 for the main data series.

When I try to retrieve values out of the 1 Day bars it fails because CurrentBars[1] is always == -1 no matter where I am in the chart, there is never anything in there. I don't know what I'm doing wrong here. Why can't I access the 1 day data?

protected override void Initialize()
        {            
            Overlay = true;
            Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "Long Term High"));
            Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "Short Term Low")); 
            Add(new Plot(Color.FromKnownColor(KnownColor.Red), PlotStyle.Line, "Long Term Low")); 
            Add(new Plot(Color.FromKnownColor(KnownColor.Red), PlotStyle.Line, "Short Term High"));
            
            Add(PeriodType.Day, 1); 
        }

It seems like if you never call OnBarUpdate for the second data series, you're not going to have any data in BarsArray[1], and that's why you're seeing that CurrentBars[1] == -1.

I'm supposed to call OnBarUpdate myself for the extra data series? The documentation makes it seem like this is automatically done by their API for you, and you just have to handle the BarsInProgress == 1 or == 2 cases?

volkie,

You need to ensure that you have historical data for the daily bars as well in order for it to work. Try loading another chart full of daily data. OnBarUpdate() doesn't need to be called manually. It is called on every historical bar.

You may also want to try using Try/Catch to see if you can catch any errors the compiler misses.
