Yes, but this is the barcount for QQQQ.
If you have no data in TestArray, there is no barcount (well maybe 0
works). Barcount is per ticker and depends on how much data is there.
Do as Graham suggested and populate a dummy ticker or duplicate another
one, like QQQQ, and rename to TestArray. You can zero out the values or
replace them with a loop.

| 1.) Show the chart of QQQQ (data from March 2000 to present)
| 2.) Click analysis, commentary. Click load and open the script
| containing only the two lines shown below.
| 3.) Click apply, then commentary tab. Says "barcount is 1,634.000"
| 4.) Close Commentary
| 5.) Click analysis, formula editor, open same script opened in
| Commentary. Click apply indicator. Get the "Subscript out of
| range..." error.
