做个预警公式 当出现买点的时候能够预警

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);
DRAWTEXT(bu,LOW,'买'),ALIGN1,VALIGN0,colorred,linethick3;
DRAWTEXT(sel,HIGH,'卖'),ALIGN1,VALIGN2,colorgreen,linethick3;
STICKLINE(买线>=卖线,LOW,HIGH,0.1,1),colorred;
STICKLINE(买线>=卖线,CLOSE,OPEN,8,1),colorred;
STICKLINE(买线<卖线,CLOSE,OPEN,8,0),color00ff00;
STICKLINE(买线<卖线,LOW,HIGH,0.1,1),color00ff00;
STICKLINE(CROSS(买线,卖线) OR CROSS(卖线,买线),OPEN,CLOSE,6,0),colorffff00;
指导线:EMA((EMA(CLOSE,4)+EMA(CLOSE,6)+EMA(CLOSE,12)+EMA(CLOSE,24))/4,2),linethick1,ColorFFffFF;
界:MA(CLOSE,27),linethick1,Color00FFFF;
主线:(MA(CLOSE,6)+MA(CLOSE,12)+MA(CLOSE,24)+MA(CLOSE,36))/4,LINETHICK2,COLORFF00FF;
BBI:=(MA(CLOSE,3)+MA(CLOSE,6)+MA(CLOSE,12)+MA(CLOSE,24))/4,COLORFFFFFF;
STICKLINE(指导线>主线,BBI,主线,1,0),LINETHICK2 ,coloryellow;
