You request involves alot of stuff; the first thing that you need to do is search the forums for "sqlplus". This will help you get the best start in the right direction.

your shell script may look like this

//to read from file
cat filename |while read line
do
//do some thing
//create sql script
echo "sql command" >>query.sql
//connect to database
sqlplus username/password@query.sql<<STOP
STOP
done

Just be careful with comments. Proper shell comments are with the # character, not //.

Do it all in PL/SQL

UTL_FILE.FOPEN()
LOOP

EXIT WHEN End of file

UTL_FILE.GET_LINE()
Perform update using TradeNo

END LOOP
UTL_FLE.FCLOSE()
