# TODAY'S POTENTIAL EARNINGS PLAYS - Shows only stocks with earnings tonight or tomorrow morning
#
# Scan tab study that selects stocks with earnings either after the
# market today or before the market opens tomorrow. To find stocks
# *without* earnings, see my other thinkScript:

# I created this because the default TOS Earnings filter is useless for
# actually highlighting earnings plays.  For example, when set to 2 days,
# it includes both stocks that already had earnings this morning, as
# well as those that won't release until tomorrow afternoon.
#
# If (for some reason) you want to look further ahead, you may adjust the
# days input.  For example, when set to 2, this will find all stocks having
# earnings through the market open on the day after tomorrow.
