the original MACD with high efficiency con div detecting algorithm with 2 point confirmation .
even so it fail to detect some long tern div con ,
signal cancelation is done when MACD move beyond the signal level or trend pattern with 2 candle with trend direction .
by when macd line is green and cross above the signal line when macd below 0 or macd only cross above 0 level and turn green
and opposite for sell .
