网友求助：
RSV1:=(CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100;
K1:=SMA(RSV1,5,1);
D1:=SMA(K1,5,1);
J1:=3*K1-2*D1;
AA1:=EMA(J1,5);
AA2:=REF(AA1,1);
STICKLINE(AA1>AA2,AA1,AA2,3,0),COLOR0055AA;
STICKLINE(AA1>AA2,AA1,AA2,2,0),COLOR0099DD;
STICKLINE(AA1>AA2,AA1,AA2,1,0),COLOR01BEE7;
STICKLINE(AA1<=AA2,AA1,AA2,3,0),COLOR006600;
STICKLINE(AA1<=AA2,AA1,AA2,2,0),COLOR00BB00;
STICKLINE(AA1<=AA2,AA1,AA2,1,0),COLOR00CC00;
STICKLINE(C>0,AA1,AA2,0,0),COLORFFFFFF;
RSV2:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K2:=SMA(RSV2,3,1);
D2:=SMA(K2,3,1);
J2:=3*K2-2*D2;
BB1:=EMA(J2,5);
BB2:=REF(BB1,1);
STICKLINE(BB1>BB2,BB1,BB2,2.8,0),COLOR000045;
STICKLINE(BB1>BB2,BB1,BB2,2,0),COLOR0000C5;
STICKLINE(BB1>BB2,BB1,BB2,1,0),COLOR0000E5;
STICKLINE(BB1<=BB2,BB1,BB2,2.8,0),COLOR353500;

STICKLINE(BB1<=BB2,BB1,BB2,1,0),COLOR858500;
STICKLINE(C>0,BB1,BB2,0,0),COLORFFFFFF;
DD:=AA1>AA2 AND BB1>BB2;
注意买入:=DD AND NOT(REF(DD,1)) AND (AA1<50 OR BB1<50) ;
DRAWICON(注意买入,-5,1);
请将 共振副图指标刚出现第一根红柱信号时作为预警选股 ，谢谢
解答如下：
RSV2:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K2:=SMA(RSV2,3,1);
D2:=SMA(K2,3,1);
J2:=3*K2-2*D2;
BB1:=EMA(J2,5);
BB2:=REF(BB1,1);
CROSS(BB1>BB2,0.5);
