In 1975 Congress enacted legislation designed to foster the establishment of a national system for the trading of securities. Many of the goals of a national market cannot be achieved if brokers are not compelled to seek the best price when executing transactions in multiply traded securities. To date, the Securities and Exchange Commission has failed to adopt a rule either requiring or encouraging a best execution practice.
