Yes

Data series are global so can be read by all code.

Yes but there as subtle differences between:

   MyVar = Average(MyData[5], 12);

and

   MyVar = Average(MyData, 12)[5];

so test before you use these forms.

I am guessing that you have not declared the value of a
subscript used to reference the data.

You had better test that one. It would force the array to have a very
large size (equal to the array size multiplied by the MaxBarsBack
setting).

In most cases it is faster to test these kinds of things rather than
ask since they are pretty obscure and the results have been known to
be different in different versions (and releases?) of TradeStation.
