指标由2组参数算出2条类似MACD走势的彩带，当黄线由下降之后开始走平，出现红色或者紫色柱子买入参考
 设89日均线作为长期均线参考。

DIFF:=EMA(CLOSE,13)-EMA(CLOSE,34);
 DEA:=EMA(DIFF,9);
 AA:=MA(DEA,21);
 AB:=MA(AA,5);
 SL:MA(DIFF,89),coloryellow,LINETHICK1;
 STICKLINE(AA>AB,AA,AB,3,0),colormagenta;
 STICKLINE(AA<AB,AA,AB,3,0),colorcyan;
 STICKLINE(DIFF>DEA,DIFF,DEA,3,0),colorred;
 STICKLINE(DIFF<DEA,DIFF,DEA,3,0),colorgreen;
