Indicator Multi Instrument Value

[YevhenShynkarenko]

Hello!
I'm Trying to plot Close prices into indicator from diffirent instruments
Want to plot two lines in indicator.
I added two Plots and one add data series.
F.e. CL 11-19 & CL 12-19

I'm using thic code to Plot them:

if (CurrentBars[0] <= BarsRequiredToPlot || CurrentBars[1] <= BarsRequiredToPlot)
return;
if (BarsInProgress == 0){
Values[0][0] = Closes[0][0];
}

if (BarsInProgress == 1){
Values[1][0] = Closes[1][0];
}

But it only works in real-time data. How can I see it on History? It shows fixed difference for me between that instruments. But if I showing only one of them - it shows me correct prices. The trouble is that when I'm trying to display both of them - it shows me incorrect history data. Thanks.

I found the problem. But need help how to resolve it.
I updated my code to next:

protected override void OnBarUpdate()
{
if(CurrentBar == 0)
return;

if(State == State.Historical)
{
current = Close[0];
next = Closes[1][0];
Value[0] = current;
Values[1][0] = next;
Print(ToTime(Time[0]));
Print("Value 0: " + " : " + current);
Print("Value:1-0: " + " : " + next);
}
if(State == State.Realtime)
{
}


}

And then I saw in Output window that it calculates two times on each bar (it prints me time two times). And on first calculation it shows me correct prices, but on second it sets both on "next" double. So then it draws in one single line my both plots. What I need to do to calculate it only once?

Thanks.

Hello YevhenShynkarenko, thanks for your note.

This works for me on historical data:

        else if (State == State.Configure)
            {
                AddDataSeries("CL 11-19");
            }

        ...

        protected override void OnBarUpdate()
        {
            if(BarsInProgress == 0)
            {
                Plot0[0] = Closes[0][0];
            }

            if(BarsInProgress == 1)
            {
                Plot1[0] = Closes[1][0];
            }
        }

They print the same data while running on a CL 12-19 chart. I also attached my test script. Could you test the same?
