零下二金选股公式

SHORT:=12;
LONG:=26;
MID:=9;
DIF:=EMA(CLOSE,SHORT)-EMA(CLOSE,LONG);
DEA:=EMA(DIF,MID);
AK1:=DIF<0 AND DEA<0;
AK2:=AK1!=REF(AK1,1) AND AK1;
AK3:=COUNT(CROSS(DIF,DEA),BARSLAST(AK2))=1 AND CROSS(DIF,DEA) AND AK1;
AK4:=COUNT(CROSS(DIF,DEA),BARSLAST(AK2))=2 AND CROSS(DIF,DEA) AND AK1;
AK5:=REF(DIF,BARSLAST(AK3))<=REF(DIF,BARSLAST(AK4));
零下二金:AK4 AND AK5;

九毛八公式解读

SHORT赋值:12
LONG赋值:26
MID赋值:9
DIF赋值:收盘价的SHORT日指数移动平均-收盘价的LONG日指数移动平均
DEA赋值:DIF的MID日指数移动平均
AK1赋值:DIF<0 AND DEA<0
AK2赋值:AK1不等于1日前的AK1 AND AK1
AK3赋值:统计上次AK2距今天数日中满足DIF上穿DEA的天数=1 AND DIF上穿DEA AND AK1
AK4赋值:统计上次AK2距今天数日中满足DIF上穿DEA的天数=2 AND DIF上穿DEA AND AK1
AK5赋值:上次AK3距今天数日前的DIF<=上次AK4距今天数日前的DIF
