把(黑火药)和(买入时机)合并成一条选股公式

编写要求：

黑火药选股公式：N:=9;M1:=3;短线:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;中线:=SMA(短线,M1,1);BB:=IF(BARSLAST(CROSS(中线,短线))>=3 AND CROSS(短线,中线) AND 中线<30,20,0);XG:BB>0;买入时机选股公式：VARA:=REF(LOW,1); VARB:=SMA(ABS(LOW-VARA),3,1)/SMA(MAX(LOW-VARA,0),3,1)*100; VARC:=EMA(IF(CLOSE*1.3,VARB*10,VARB/10),3); VARD:=LLV(LOW,30); VARE:=HHV(VARC,30); RSV:=(((CLOSE - LLV(LOW,9)) / (HHV(HIGH,9) - LLV(LOW,9))) * 100); K:=SMA(RSV,3,1); D:=SMA(K,3,1); J:=3*K-2*D; X:=LLV(J,2)=LLV(J,8); 买入时机: IF(CROSS(J,3),65,0),COLORFF00FF,LINETHICK3; DRAWTEXT(买入时机,70.1,' 跟庄'),COLOR00FF00;

解答：

N:=9;
M1:=3;
短线:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
中线:=SMA(短线,M1,1);
BB:=IF(BARSLAST(CROSS(中线,短线))>=3 AND CROSS(短线,中线) AND 中线<30,20,0);
AA:=BB>0;

RSV:=(((CLOSE - LLV(LOW,9)) / (HHV(HIGH,9) - LLV(LOW,9))) * 100);
K:=SMA(RSV,3,1);
D:=SMA(K,3,1);
J:=3*K-2*D;
X:=LLV(J,2)=LLV(J,8);
买入:=CROSS(J,3);
XG:AA AND 买入;
