将MACD出现零上金叉大于零时做个预警公式

编写要求：

请老师帮我在出现零上金叉大于零时做个预警公式.如下图所示,谢谢!DIFF:EMA(CLOSE,12) - EMA(CLOSE,26);DEA:EMA(DIFF,9);MACD:2*(DIFF-DEA), COLORSTICK;WW:=DEA>REF(DEA,1);DD:=CROSS(DIFF,REF(DIFF,1));反身向上:WW AND DD,COLORFF00FF,LINETHICK2;空中加油:IF(DIFF>0 AND DEA>0 AND CROSS(DIFF,DEA)AND MACD>REF(MACD,1),0.8,0)COLORRED,LINETHICK2;OZ:=COUNT(CROSS(DIFF,DEA) AND DIFF>0,BARSLAST(CROSS(DIFF,DEA) AND DIFF<0));零上二金叉:IF(CROSS(DIFF,DEA) AND OZ=1,0.6,0)COLORFFFF00,LINETHICK2;DRAWICON(CROSS(DIFF,DEA),DEA,1); 低位金叉:=CROSS(DIFF,DEA) AND DIFF<-0.1;STICKLINE(低位金叉,0,0.3,8,0),COLORYELLOW;JCCOUNT:=COUNT(CROSS(DIFF,DEA),BARSLAST(DEA>=0));二次金叉:=CROSS(DIFF,DEA) AND DEA<0 AND COUNT(JCCOUNT=2,21)=1;STICKLINE(二次金叉,0,0.2,8,0),COLORFF80FF;DRAWICON(二次金叉,DEA*0.9,1);A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));底背离:=REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA);STICKLINE(底背离,0,0.1,8,0),COLORRED;DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED,LINETHICK2;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),COLORGREEN,LINETHICK2;DRAWICON(CROSS(DIFF,DEA),DEA,1);

解答：

DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
