Try this with your test files

Code:
for i in `sort -u file1`; do trade_id=`echo $i | cut -d"~" -f1`; yday_value=`echo $i | cut -d"~" -f2`; grep -m 1 $trade_id file2 >/dev/null && echo -n "$trade_id~$yday_value" && grep -m 1 $trade_id file2 | awk -F"~" '{print "~"$2}'; done

is this what you want?
Code:
awk -F~ 'NR==FNR{_1[$1]=$2;next} $1 in _1{print $1"~"_1[$1]"~"$2}' file1 file2
