Access a DataSeries obj in another chart window

[Tight Face]

Hi, I am making an indicator that requires the values (DataSeries) from two instruments. This is how I have it set up (there may be a better way to do this, if so let me know).

Chart 1:

Instrument A
- IndicatorXXX based on instrument A price
- IndicatorYYY (the indicator that pulls indicator values from both indicatorXXX on instrument A and B)

Chart 2:

Instrument B
- IndicatorXXX based on instrument B price

So I can access the indicatorXXX in the instrument A from indicatorYYY, but I am not sure how to get that DataSeries from the indicatorXXX in the B instrument.

This is the line that works for the A instrument...

PlotInstA.Set(IndicatorXXX().MALine[0]);

I did a little more digging after finding nothing in IntelliSense. It looks like the answer is no (in indicators)... I just assumed it was possible because I can do it in strategy mode.

Correct. This limitations will be overcome with NT7.
