公式源码：

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; 

X:=LLV(J,2)=LLV(J,8); 

买入时机: IF(CROSS(J,3),65,0),COLORFF00FF,LINETHICK3;

趋势:=3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1),COLOR00FFFF; 

秘密买点: IF(趋势<=3,20,0),COLOR00FF00,LINETHICK3; 

机构建仓: IF(趋势<5,40,0),COLORFFFFFF,LINETHICK3;
