指标很好用，请论坛各位老师帮忙写个选股指标，1 在起黄色柱红色向上箭头选股，2 在界点线金叉操盘线写个选股

 买线:=EMA(C,2);
卖线:=EMA(SLOPE(C,21)*20+C,42);
 BU:=CROSS(买线,卖线);
SEL:=CROSS(卖线,买线);
DRAWICON(BU,L-0.1,1);
 DRAWICON(SEL,H+0.1,2);
 STICKLINE(买线>=卖线,LOW,HIGH,0.0,1),COLORRED;
 STICKLINE(买线>=卖线,CLOSE,OPEN,2,1),COLORRED;
 STICKLINE(买线<卖线,LOW,HIGH,0.0,1),COLORGREEN;
 STICKLINE(买线<卖线,CLOSE,OPEN,2,1),COLORGREEN;
 STICKLINE(BU,OPEN,CLOSE,2,0),COLORYELLOW;
