4個月的月最高和月最低嗎？

nn1:=sumbars(month<>ref(month,1),1);
nn2:=sumbars(month<>ref(month,1),2);
nn3:=sumbars(month<>ref(month,1),3);
nn4:=sumbars(month<>ref(month,1),4);

jc1:=(ref(hhv(h,nn1),nn1)-ref(llv(l,nn1),nn1))/ref(llv(l,nn1),nn1);

jc4:=(ref(hhv(h,nn1),nn4)-ref(llv(l,nn1),nn4))/ref(llv(l,nn1),nn1);

jc1>0.03 and jc2>0.03 and jc3>0.03 and jc4>0.03;
