Plot indicators using multibar data periods

[dbooksta]

Why doesn't the following display the SMA(10) curve for the second 30-minute timeframe?

        protected override void Initialize()
        {   
			Add(PeriodType.Minute, 30);

			SMA(50).Plots[0].Pen.Color = Color.Blue;
			Add(SMA(50));
			
			SMA(BarsArray[1], 10).Plots[0].Pen.Color = Color.Orange;
			SMA(BarsArray[1], 10).Plots[0].Pen.DashStyle = DashStyle.Dot;
			Add(SMA(BarsArray[1], 10));

What would be the correct way to do this? (Ignore the fact that an SMA might be restated in terms of the highest-frequency timeframe, since for many other indicators that relationship doesn't hold.)

Hello Dbooksta,

Thank you for your post.

You would not be able to add an indicator with a different data series than the primary.
The reason for this in the method you provided, the BarsArray has not loaded and would not always work.

It is not recommended to use the BarsArray in the Initialize() method
