ATFireworks2 is an anti trading strategy. It uses Aroon 25 and 50 time
periods to determine buy or sell positons. If Aroon Down is above 90
in both periods (25 and 50), a buy positon is opened and all existing
sell positions are stopped. If Aroon Up is above 90 in both periods
(25 and 50), a sell positon is opened and all existing buy positions
stopped.
