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;

N1:=6;
