AA:=(O-REF(C,1))/REF(C,1)>=0.06 AND (L-REF(C,1))/REF(C,1)>=0.04;
ZT:=(C-REF(C,1))/REF(C,1)>=0.095 AND H!=L AND (O-L)/L>0.01;
TB:=AA AND ZT;
一字涨停:=C/REF(C,1)>1.09 AND L=H ;
X1:=C/REF(C,1)>1.098 AND NOT(一字涨停) AND NOT(TB);
X2:=(REF(C,1)-C)/REF(C,1)*100>2.5 AND V<REF(V,1);
REF(X1,2) AND REF(X2,1) AND O<REF(L,1) AND C<O AND V<REF(V,1);
