把下面公式出现"低位金叉"字样,改成选股公式

编写要求：

DIFF: EMA(CLOSE,12)-EMA(CLOSE,27),LINETHICK0,COLOR00FFFF; DEA: EMA(DIFF,9),LINETHICK0,COLORFF00FF; MACD:= 2*(DIFF-DEA); STICKLINE(MACD>=0,MACD,0,4,1),COLORF00FF0; STICKLINE(MACD0,0,MACD,4,0),COLOR00AAFF; STICKLINE(MACD0,0,MACD,3.3,0),COLOR00BBFF; STICKLINE(MACD0,0,MACD,2.2,0),COLOR00CCFF; STICKLINE(MACD0,0,MACD,1.65,0),COLOR00DDFF; STICKLINE(MACD0,0,MACD,1.1,0),COLOR00EEFF; STICKLINE(MACD0,0,MACD,0.55,0),COLOR00FFFF; STICKLINE(MACD>=REF(MACD,1) AND MACD>0,0,MACD,4,0),COLOR0000AA; STICKLINE(MACD>=REF(MACD,1) AND MACD>0,0,MACD,3.3,0),COLOR0011BB; STICKLINE(MACD>=REF(MACD,1) AND MACD>0,0,MACD,2.2,0),COLOR0022CC; STICKLINE(MACD>=REF(MACD,1) AND MACD>0,0,MACD,1.65,0),COLOR0033DD; STICKLINE(MACD>=REF(MACD,1) AND MACD>0,0,MACD,1.1,0),COLOR0044EE; STICKLINE(MACD>=REF(MACD,1) AND MACD>0,0,MACD,0.55,0),COLOR0055FF; STICKLINE(MACD>REF(MACD,1) AND MACDREF(MACD,1) AND MACDREF(MACD,1) AND MACDREF(MACD,1) AND MACDREF(MACD,1) AND MACDREF(MACD,1) AND MACDDEA,DEA,DEA),COLORFFFFFF; 低位金叉:= CROSS(DIFF,DEA) AND DIFF=0)); 二次金叉:= CROSS(DIFF,DEA) AND DEACLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA); STICKLINE(底背离,0,0.13,6,0),COLOR00FF00; DRAWLINE(A1=0,DEA,底背离,DEA,0),COLOR0000FF; DRAWTEXT(底背离,0.1,' 底背离'),COLOR00FF00; A2:= BARSLAST(REF(CROSS(DEA,DIFF),1)); 顶背离:= REF(CLOSE,A2+1)DIFF AND CROSS(DEA,DIFF); DRAWLINE(A2=0,DEA,顶背离,DEA,0),COLOR008000;

股票网解答：

DIFF:= EMA(CLOSE,12)-EMA(CLOSE,27);

DEA: =EMA(DIFF,9);

MACD:= 2*(DIFF-DEA);

低位金叉:CROSS(DIFF,DEA) AND DIFF<(-0.1);
