改为条件选股公式（红箭头买入）_图片免费下载

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;

K:SMA(RSV,3,1);

D:SMA(K,3,1);

J:3*K-2*D;

N:=7;

IF(J>=REF(J,1),J,DRAWNULL),COLORRED;

IF(J<REF(J,1),J,DRAWNULL),COLORFFFF11;

IF(J<0,J,DRAWNULL),COLORYELLOW,LINETHICK2;

IF(K>90,K,DRAWNULL),COLORGREEN,LINETHICK2;

IF(D>85,D,DRAWNULL),COLORGREEN,LINETHICK2;

AA1:=DRAWLINE(J>=HHV(J,N),J,J<=LLV(J,N),J,0);

AA2:=DRAWLINE(J<=LLV(J,N),J,J>=HHV(J,N),J,0);

AA3:=J=AA2;

AA4:=J=AA1;

AA5:=J<REF(J,1);

AA6:=J>REF(J,1);

DRAWICON(FILTER(AA4 AND AA6,1),J*1.04,2);

DRAWICON(FILTER(AA3 AND AA5,1),J*0.9,1);

 

解答如下：

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;

K:=SMA(RSV,3,1);

D:=SMA(K,3,1);

J:=3*K-2*D;

AA2:=DRAWLINE(J<=LLV(J,N),J,J>=HHV(J,N),J,0);

AA3:=J=AA2;

AA5:=J<REF(J,1);

XG:FILTER(AA3

AND AA5,1);

由于DRAWLINE函数造成的漂移问题，这样的指标不建议用作选股，或者说不建议用作选出当日的股票。
