做个选股公式 《KDJ买入箭头》

编写条件：

RSV:=(C-LLV(L,9))/(HHV(H,9)-LLV(L,9))*100; K:SMA(RSV,3,1),COLORFFFFFF; D:SMA(K,3,1),COLOR00FFFF; J:3*K-2*D,COLORFF00FF; 买入时间: IF(CROSS(,100,0),COLOR0099FF,LINETHICK2; VAR1:=REF((LOW+OPEN+CLOSE+HIGH)/4,1); VAR2:=SMA(ABS(LOW-VAR1),13,1)/SMA(MAX(LOW-VAR1,0),10,1); VAR3:=EMA(VAR2,10); VAR5:=EMA(IF(LOW=LLV(LOW,33),VAR3,0),3);

编写方法：

 RSV:=(C-LLV(L,9))/(HHV(H,9)-LLV(L,9))*100;
K:=SMA(RSV,3,1),COLORFFFFFF;
D:=Sma(K,3,1),COLOR00FFFF;
J:=3*K-2*D,COLORFF00FF;
买入时间: IF(crOSS(J,2),100,0),COLOR0099FF,LINETHICK2;
