How to draw indicator of two instruments in one chart?

[algoapi]

I am working on a multi-instrument code and need to draw the indicator of two different instruments in one chart in backtesting.
For example, how can I draw RSI(EURUSD,14,3) and RSI(AUDUSD,14,3) in the same backtesting chart. They can be in different panels.
I could only add the indicator of the primary instrument in the chart, but couldn't add the indicator for the secondary instrument.

Below is my code:

protected override void Initialize()
{
Add("$AUDUSD", PeriodType.Minute, 10);
Add(RSI(Close,14,3)); // add RSI of the primary instrument EURUSD
Add(RSI(BarsArray[1],14,3)); // try to add RSI of 2nd instrument but is wrong
}

Could someone point out the error in the 3rd line of the above code in blue color?
Also thanks a lot if anyone can provide sample code....

To really understand the issue, you may want to read the thread in threaded or hybrid display mode.

Thank you Koganam for the help!

I tested your code but it seems the chart still only displays the primary instrument, not the secondary instrument ("AAPL"), did I miss anything here?

Below is the code (edited based on your sample) I tested. Basically I want the chart to display both RSI(CSCO) in one pane, and RSI(AAPL) in another pane. But the result chart only displays RSI(CSCO). Any idea?

protected override void Initialize()
{
CalculateOnBarClose = true;

Add("AAPL", PeriodType.Minute, 5);

this.myRSI = RSI(Close, 14, 3);

Add(this.myRSI);

Add(RSI(Close,14,3));
}

protected override void OnStartUp()
{
this.myRSI = RSI(Closes[1], 14, 3);
// this.myRSI = RSI(BarsArray[1], 14, 3);
}


Thanks again!
