超前MACD公式改为选股公式

编写要求：

SQX:=(C-MA(CLOSE,13))*100; DIFF:EMA(MA(SQX,7),1),COLOR00FFFF,LINETHICK2; DEA:EMA(DIFF,7),COLORFF33FF,LINETHICK2; MACD: (DIFF-DEA)*2,COLORSTICK; 低位金叉:IF(CROSS(DIFF,DEA) AND DIFF<-0.1,0.3,0),COLORYELLOW,POINTDOT; STICKLINE(低位金叉,0,15,8,0),COLORYELLOW; DRAWICON(低位金叉,0.3,1); JCCOUNT:=COUNT(CROSS(DIFF,DEA),BARSLAST(DEA>=0)); 二次金叉:IF(CROSS(DIFF,DEA) AND DEA<0 AND COUNT(JCCOUNT=2,21)=1,0.2,0),COLORFF00FF,POINTDOT; STICKLINE(二次金叉,30,15,8,0),COLORFF00FF; A1:=BARSLAST(REF(CROSS(DIFF,DEA),1)); 底背离:IF(REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA),0.1,0),COLORRED,POINTDOT; STICKLINE(底背离,45,30,8,0),COLORRED; DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED; A2:=BARSLAST(REF(CROSS(DEA,DIFF),1)); 顶背离:REF(CLOSE,A2+1)DIFF AND CROSS(DEA,DIFF),COLORGREEN; DRAWLINE(A2=0,DEA,顶背离,DEA,0),COLORGREEN; A3:=CROSS(DIFF,DEA) AND DEA<0; 零下二次金叉:IF(FILTER(COUNT(A3,21)=2,10),0.05,0),COLORWHITE,POINTDOT; STICKLINE(零下二次金叉,45,60,8,0),COLORWHITE; 请老师帮忙改成两线（DIFF和DEA）在零轴下呈现多头向上（一定得在零轴下呈现多头）的选股公式，谢谢

解答：

?SQX:=(C-MA(CLOSE,13))*100;

DIFF:=EMA(MA(SQX,7),1);
