多空线二次金叉选股

X:=(3*C+L+O+H)/6;
多空1:=(20*X+19*REF(X,1)+18*REF(X,2)+17*REF(X,3)+16*REF(X,4)+15*REF(X,5)+14*REF(X,6)
+13*REF(X,7)+12*REF(X,8)+11*REF(X,9)+10*REF(X,10)+9*REF(X,11)+8*REF(X,12)
+7*REF(X,13)+6*REF(X,14)+5*REF(X,15)+4*REF(X,16)+3*REF(X,17)+2*REF(X,18)+
REF(X,20))/210;
DIFF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MACD:=2*(DIFF-DEA);
金叉2:=CROSS(DIFF,DEA) AND DIFF<-0.1;
JCCOUNT:=COUNT(CROSS(DIFF,DEA),BARSLAST(DEA>=0));
理想选股XG:CROSS(C,多空1) AND CROSS(DIFF,DEA) AND DEA<0 AND COUNT(JCCOUNT=2,21)=1;
