指标源码：
MAA5:MA(C,5);
MAA10:=MA(C,10);
MAA30:MA(C,30);
KS:IF(MAA10>MAA30,MAA10,MAA30);
A3:=(C-LLV(L,9))/(HHV(H,9)-LLV(L,9))*100;
A4:=SMA(A3,3,1);
A5:=SMA(A4,3,1);
A6:=3*A4-2*A5;
A7:=C-REF(C,1);
A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);
买:=LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2));
DRAWTEXT(FILTER(买=1,5),LOW-0.05,'↖买进'),COLORYELLOW;
STICKLINE(买,OPEN,CLOSE,2,0),COLORYELLOW;

请高手帮把指标中发出“买进”的点做成选股指标。万分感谢！！
