Modification entry and exit.
Entry-wait until MA get cross after MACD cross(no matter MACD direction at that time)
Exit-close if MA cross(short MA, long MA) even though before MACD cross, likewise close if MACD cross even though before MA cross
1. When MACD cross if MA is same direction, open position
2. When MACD cross but MA is opposite direction, then put it a queue and check if MA get cross
(during waiting, ea does not care any change of MACD direction- ea does not drop this pair from queue even though MACD direction get opposite)
