请大神们给下面通达信公式写个选股公式，要求：出现红色箭头买入了预警！

H1:=MAX(DYNAINFO(3),DYNAINFO(5));

L1:=MIN(DYNAINFO(3),DYNAINFO(6));

P1:=H1-L1;

阻力:=L1+P1*7/8;

支撑:=L1+P1*0.5/8;

中线:=(支撑+阻力)/2;

V11:=3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA(SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1),3,1);

趋势线:=EMA(V11,3),LINETHICK2,COLORLIMAGENTA;

V12:=(趋势线-REF(趋闷握势线,1))/REF(趋势线,1)*100;

AA:=(趋势线<11) AND FILTER((趋喊枯势线<=11),15) AND C<中线;

REF(趋势线,1)<11 AND CROSS(趋势郑罩洞线,11) AND C<中线;
