根据ZLGJ思路，变换不同周期写了三个选股公式，看了一下效果还可以

A1:=(HHV(HIGH,5)-LLV(LOW,5))/EMA((CLOSE-LLV(LOW,5)),5);
 A2:=(HHV(HIGH,9)-LLV(LOW,9))/EMA((CLOSE-LLV(LOW,9)),5);
 A3:=(HHV(HIGH,25)-LLV(LOW,25))/EMA((CLOSE-LLV(LOW,25)),5);

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;
 XG1:CROSS(L,A1)*H AND J>REF(J,1);
 XG2:CROSS(L,A2)*H AND J>REF(J,1);
 XG3:CROSS(L,A3)*H AND J>REF(J,1);
