二次金叉KDJ选股

指标如下：

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;
J线落差:REF(J,1)-J,NODRAW;
DRAWICON(CROSS(K,D),D*0.98,1);
DRAWICON(CROSS(D,K),D*0.98,2);

80,;
20,;

求选股公式，让这次金叉比前一次金叉的高点高，谢谢！

老K股票学习网解答：

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=SMA(RSV,3,1);
D:=SMA(K,3,1);
JC:=CROSS(K,D);A:=BARSLAST(REF(JC,1));
XG:K>REF(K,A+1) AND JC;
