在买入指标出现红箭头时做个选股公式

编写要求：

M:=14;N1:=6;N:=9;100,POINTDOT;-100,POINTDOT;{INPUT:N(9,2,100),M(14,1,100),N1(6,2,100);}TYP := (HIGH + LOW + CLOSE)/3;CC1:(TYP-MA(TYP,M))/(0.015*AVEDEV(TYP,M)),COLORFF00FF;C1:=SMA(CC1,3,1);C2:=SMA(C1,3,1);C3:=3*C1-2*C2;CB1:=EMA(C3,5);CB2:=REF(CB1,1);{FILLRGN(CC1,100,CC1>100),COLOR38FF00;FILLRGN(CC1,-100,CC1<-100),COLOR00AAFF;}DRAWBAND(CC1,RGB(0,255,56),100,1);DRAWBAND(100,RGB(0,0,0),-100,RGB(0,0,0));LC := REF(CLOSE,1);RSI1:=SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*100;RSI:(RSI1-50)*5,LINETHICK2,COLORFFFFFF;R1:=SMA(RSI,3,1);D1:=SMA(R1,3,1);J1:=3*R1-2*D1;RR1:=EMA(J1,5);RR2:=REF(RR1,1);RR:=RR1>RR2;RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;K:=SMA(RSV,3,1);K1:(K-50)*5,COLORFFFF00;K2:=SMA(K1,3,1);D2:=SMA(K2,3,1);J2:=3*K2-2*D2;BB1:=EMA(J2,5);BB2:=REF(BB1,1);买入:RR AND NOT(REF(RR,1)) AND (RR1<-100 AND BB1<-100) AND CB1<-100,LINETHICK0;DRAWICON(买入,-200,1);卖出:REF(RR,1)=1 AND NOT(RR) AND CB1>100,LINETHICK0;DRAWICON(卖出,200,2);出现红箭头时做个选股公式

解答：

 M:=14;
