公式编写说明：
请老师改个选股公式：最近3天内MACD金叉，并且出现“买”（金叉和买可以是同一天出现或相继出现），谢谢！DIFF:EMA(CLOSE,7) - EMA(CLOSE,19);DEA:EMA(DIFF,9);MACD:2*(DIFF-DEA),COLORSTICK;A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)<DIFF AND CROSS(DIFF,DEA);A2:=BARSLAST(REF(CROSS("KDJ.K"(9,3,3),"KDJ.D"(9,3,3)),1));B2:=REF(C,A2+1)>C AND REF("KDJ.K"(9,3,3),A2+1)<"KDJ.K"(9,3,3) AND CROSS("KDJ.K"(9,3,3),"KDJ.D"(9,3,3));A3:=BARSLAST(REF(CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24)),1));B3:=REF(C,A3+1)>C AND REF("RSI.RSI1"(6,12,24),A3+1)<"RSI.RSI1"(6,12,24) AND CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24));C1:=BARSLAST(REF(CROSS(DEA,DIFF),1));D1:=REF(C,C1+1)<C AND REF(DIFF,C1+1)>DIFF AND CROSS(DEA,DIFF);C2:=BARSLAST(REF(CROSS("KDJ.D"(9,3,3),"KDJ.K"(9,3,3)),1));D2:=REF(C,C2+1)<C AND REF("KDJ.K"(9,3,3),C2+1)>"KDJ.K"(9,3,3) AND CROSS("KDJ.D"(9,3,3),"KDJ.K"(9,3,3));C3:=BARSLAST(REF(CROSS("RSI.RSI2"(6,12,24),"RSI.RSI1"(6,12,24)),1));D3:=REF(C,C3+1)<C AND REF("RSI.RSI1"(6,12,24),C3+1)>"RSI.RSI1"(6,12,24) AND CROSS("RSI.RSI2"(6,12,24),"RSI.RSI1"(6,12,24));M底背:IF(B1>0,-0.1,0),COLORRED,POINTDOT;K底背:IF(B2>0,-0.1,0),COLORFF00FF,POINTDOT;R底背:IF(B3>0,-0.1,0),COLORYELLOW,POINTDOT;MACD顶背:=IF(D1>0,0.1,0),COLOR00FF00,POINTDOT;KDJ顶背:=IF(D2>0,0.1,0),COLORFFCC66,POINTDOT;RSI顶背:=IF(D3>0,0.1,0),COLORWHITE,POINTDOT;STICKLINE(B1>0,-0.1,0,2,0),COLORRED;STICKLINE(B2>0,-0.1,0,2,0),COLORFF00FF;STICKLINE(B3>0,-0.1,0,2,0),COLORYELLOW;STICKLINE(D1>0,0.1,0,2,0),COLOR00FF00;STICKLINE(D2>0,0.1,0,2,0),COLORFFCC66;STICKLINE(D3>0,0.1,0,2,0),COLORWHITE;STICKLINE(MACD>REF(MACD,1) AND MACD>0,0,MACD,0,0),COLORRED;STICKLINE(MACD<=REF(MACD,1) AND MACD>0,0,MACD,0,0),COLORYELLOW;STICKLINE(MACD<REF(MACD,1) AND MACD<0,0,MACD,0,0),COLORCYAN;STICKLINE(MACD>=REF(MACD,1) AND MACD<0,0,MACD,0,0),COLORMAGENTA;STICKLINE(C>0,0,0,50,1),COLORBLUE;强:IF(DIFF>MA(DIFF,2),DIFF,DRAWNULL),COLORRED,LINETHICK2;弱:IF(DEA>MA(DEA,2),DEA,DRAWNULL),COLORMAGENTA,LINETHICK2;DRAWICON(CROSS(DIFF,DEA),DEA,26);DRAWICON(CROSS(DEA,DIFF),DEA,27);A:=REF(DIFF,1)<REF(DIFF,2) AND REF(DIFF,2)<REF(DIFF,3) AND DIFF>REF(DIFF,1);B:=REF(DIFF,1)>REF(DIFF,2) AND REF(DIFF,2)>REF(DIFF,3) AND DIFF<REF(DIFF,1);DRAWICON(A,DIFF,1);DRAWICON(B,DIFF,2);AA:=CLOSE-REF(MA(CLOSE,20),10);M3:EMA(AA,3),LINETHICK1,COLORMAGENTA;STICKLINE(M3>=REF(M3,1),M3,REF(M3,1),3,1),COLORYELLOW;STICKLINE(M3<REF(M3,1),M3,REF(M3,1),3,1),COLORFF9900;买:EMA(AA,10),COLORBLUE;DRAWTEXT(CROSS(M3,买),REF(M3,1),'买'),COLORRED;STICKLINE(CROSS(M3,买),M3,REF(M3,1),3,0),COLORRED;DRAWTEXT(CROSS(买,M3),REF(M3,1)*1.2,'卖'),COLORGREEN;STICKLINE(CROSS(买,M3),M3,REF(M3,1),3,0),COLORGREEN;
公式源码回答：
DIFF:=EMA(CLOSE,7) - EMA(CLOSE,19);
DEA:=EMA(DIFF,9);
AA:=CLOSE-REF(MA(CLOSE,20),10);
M3:=EMA(AA,3);
买:=EMA(AA,10);
XG:COUNT(CROSS(DIFF,DEA),3)=1 AND COUNT(CROSS(M3,买),3)=1;
