把拉升抓住指标白线上传黄线做个选股

编写要求：

A:=(C-MA(C,250))/MA(C,250)*100,COLOR00FFFF,LINETHICK2; A5:=EMA(A,5),COLOR4080FF; MAA20:=EMA(A,20),COLORRED; N1:=BARSLAST(CROSS(C,MA(C,250))); N2:=BARSLAST(CROSS(MA(C,250),C)); N1A:=BARSLAST(CROSS(C,MA(C,13))); N2A:=BARSLAST(CROSS(MA(C,13),C)); RSV27:=(CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100-50; 天:SMA(RSV27,3,1),LINETHICK3,COLORWHITE; RSV89:=(CLOSE-LLV(LOW,89))/(HHV(HIGH,89)-LLV(LOW,89))*100-50; K89:=SMA(RSV89,13,1); 地:SMA(K89,3,1),LINETHICK3,COLORYELLOW;

解答：

?RSV27:=(CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100-50;

?天:=SMA(RSV27,3,1);
