TBGAroonMACD is an Aroon Trading strategy. It uses Aroon 15min (25 and 50 time periods) and MACD (25, 50, 15) to determine buy or sell positons. If Aroon Down is above 90 in both periods (25 and 50) and MACD (MACD < SignalMACD; MACD < Hist; Hist value decrease), a down position is opened and existing buy position is stopped. If Aroon Up is above 90 in both periods (25 and 50) and MACD (MACD > SignalMACD; MACD > Hist; Hist value increase), a buy position is opened and existing sell position is stopped.
