九毛八公式指标

V1:=EMA(CLOSE,60)-EMA(CLOSE,300); V2:=EMA(V1,300); V3:=(CLOSE-LLV(LOW,8))/(HHV(HIGH,8)-LLV(LOW,8))*100; V4:SMA(V3,2,1); V5:SMA(V4,2,1); V6:=CLOSE/REF(CLOSE,3)>=1.1; V7:=BACKSET(V6,3); 买入:IF((V7 AND COUNT(V7,3)=1),30,0),COLORYELLOW,LINETHICK3; DRAWTEXT(买入,35,'买入 '),COLORYELLOW,LINETHICK3;

公式模块：

V1:=EMA(CLOSE,60)-EMA(CLOSE,300);

V2:=EMA(V1,300); V3:=(CLOSE-LLV(LOW,8))/(HHV(HIGH,8)-LLV(LOW,8))*100; V4:=SMA(V3,2,1); V5:=SMA(V4,2,1); V6:=CLOSE/REF(CLOSE,3)>=1.1; V7:=BacKSET(V6,3); 买入:V7 AND COUNT(V7,3)=1;
