You can lean on me......^--^
As i is incremented from 0 to 9 (there are 9 symbols in the list string
SYMBOLS)
until it senses the end of the list.
the logic will test to see if the symbol is in watchlist 7, 8, 9 . . . . .
15
and if it is in the watchlist it will add Advanced and Declined to the
appropriate addtocomposite array.
