把阴线买入公式改为选股公式

编写要求：

安全线:EMA((CLOSE+HIGH+LOW)/3,55),COLORF4E202,{PRECIS2短线强度}; A:=EMA(SLOPE(EMA(CLOSE,55),10)*15+CLOSE,2); SD:EMA(A,13),{COLORFF80FF,PRECIS2}, COLORRED,LINETHICK1; SK:=EMA(SLOPE(EMA(CLOSE,55),10)*15+CLOSE,2),COLOR83FFFF,{PRECIS2}; VAR11AA:=EMA(CLOSE,30)-EMA(CLOSE,17); VAR12AA:=EMA(VAR11AA,5); 九:=TROUGHBARS(3,10,1)<1 AND CROSS(VAR11AA,VAR12AA); DRAWICON(九>0,安全线,1 ); DRAWTEXT(九,安全线,'九'),COLOR000000; VAR2A:=(EMA(CLOSE,26)-EMA(CLOSE,52))/MA(CLOSE,60)*100; VAR3A:=EMA(VAR2A,18); VAR4A:=VAR2A<-1; VAR5A:=VAR4A AND CROSS(VAR2A,VAR3A); 追2:=VAR5A; 追涨C:=IF(追2>0,0.8,0),STICK,COLORYELLOW,LINETHICK4 ; XX:=EMA(CLOSE,30)-EMA(CLOSE,17); YY:=EMA(XX,13); 短针2:=TROUGHBARS(3,5,1)<1 AND XX0,0.4,0),STICK,COLORF0F000,LINETHICK4; DRAWICON(阴>0,安全线,1 ); DRAWTEXT(阴,安全线,'阴'),COLOR000000; N1:=30;N2:=17;N3:=5;N4:=6; VAR1X:=EMA(CLOSE,N1)-EMA(CLOSE,N2); VAR2X:=EMA(VAR1X,N3); 剑:=CROSS(VAR1X,VAR2X) AND TROUGHBARS(3,7,1)<1; DRAWICON(剑>0,安全线,1); DRAWTEXT(剑,安全线,'剑'),COLOR000000; 阴剑:= 九 OR 剑 OR 阴;

解答：

?VAR11AA:=EMA(CLOSE,30)-EMA(CLOSE,17);

VAR12AA:=EMA(VAR11AA,5);
