网友求助：
N1:=9;
N2:=3;
N3:=3;
RSV:=(CLOSE-LLV(LOW,N1))/(HHV(HIGH,N1)-LLV(LOW,N1))*100;
K:=SMA(RSV,N2,1);
D:=SMA(K,N3,1);
J:=3*K-2*D;
crOSS(100,J);
N2:=3;
N3:=3;
RSV:=(CLOSE-LLV(LOW,N1))/(HHV(HIGH,N1)-LLV(LOW,N1))*100;
K:=SMA(RSV,N2,1);
D:=SMA(K,N3,1);
J:=3*K-2*D;
crOSS(100,J);
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;
DRAWICON(CROSS(100,J),100,2);
100;90;0;50;10;
K:SMA(RSV,3,1);
D:SMA(K,3,1);
J:3*K-2*D;
DRAWICON(CROSS(100,J),100,2);
100;90;0;50;10;
