将主图出现买点，改为预警公式

请老师将主图出现买点出，改为预警或者选股公式，谢谢老师了。 MA1:MA(CLOSE,5); MA2:MA(CLOSE,10); MA3:MA(CLOSE,20); MA4:MA(CLOSE,60); MA5:MA(CLOSE,120); MA6:MA(CLOSE,250); 买点1:=(EMA(CLOSE,3) - EMA(CLOSE,13)); 买点2:=EMA(买点1,9); 买点3:=BARSLAST(CROSS(买点1,买点2)); 买点4:=REF(买点3,买点3+1); 买点5:=买点20,L*0.97,'买点'),COLORYELLOW; STICKLINE(买点>0,H,L,6,0),LINETHICK1,COLORRED; STICKLINE(买点>0,H,L,0.2,0),COLORYELLOW; STICKLINE(买点>0,O,C,2,0),LINETHICK1,COLORYELLOW; DRAWICON(买点>0,(H+L)/2,7);

爱约股解答：

买点1:=(EMA(CLOSE,3) - EMA(CLOSE,13));

买点2:=EMA(买点1,9);

买点3:=BARSLAST(CROSS(买点1,买点2));

买点4:=REF(买点3,买点3+1);

买点5:=买点2<REF(买点2,买点4); 

买点:CROSS(买点1,买点2) AND 买点5;
