简单的通达信波段之星公式，简单最好

第一个.波段之星

VAR2:=(HIGH+LOW+CLOSE*2)/4;
 VAR3:=EMA(VAR2,21);
 VAR4:=STD(VAR2,21);
 VAR5:=((VAR2-VAR3)/VAR4*100+200)/4;
 VAR6:=(EMA(VAR5,5)-25)*1.56;
 K: EMA(VAR6,2)*1.22;
 D: EMA(K,2);
 J: 3*K-2*D;
 130,COLORFFFF33,LINETHICK2;
底部区:STICKLINE(C>0,-20,-21,8,0),COLOREE3300;
 DRAWTEXT(CROSS(J,-25),-21*1.01,'●买'),COLORMAGENTA;
 DRAWTEXT(CROSS(145,J),130*1.11,'●卖'),COLORGREEN;

第2个.CCI买卖

{N 2 100 14}
 TYP:=(HIGH+LOW+CLOSE)/3;
 CCI:(TYP-MA(TYP,N))/(0.015*AVEDEV(TYP,N)),COLORRED;
顶:220,COLOR9966FF,LINETHICK1;
底:-190,COLOR9966FF,LINETHICK1;
顶1:280,COLOR9966FF,LINETHICK1;
底1:-250,COLOR9966FF,LINETHICK1;
 DRAWTEXT(CROSS(CCI,-201),-201*1.01,'●买一点'),COLORMAGENTA;
 DRAWTEXT(CROSS(顶,CCI),顶*1.11,'●卖一点'),COLORGREEN;
买入:IF(CCI<=-180 AND CCI<-180,CCI,DRAWNULL) COLORBLUE,LINETHICK2;
卖出:IF(CCI>=220 AND CCI>220,CCI ,DRAWNULL)COLORGREEN,LINETHICK3;
 DRAWTEXT(CROSS(CCI,250),250,'风险');
DRAWTEXT(CROSS(CCI,-200),-230,'短买');
