Brokers will be required to disclose additional information about, how they execute trade orders of large, institutional investors in accordance with a new proposal from the Securities and Exchange Commission, submitted on Wednesday. This proposal, on which the SEC voted unanimously, provide investors with formal metrics, showing, how well their trade orders were handled. This measure is key to the actions of SEC Chairman Mary Joe White to resolve conflicts of interest and non-transparency of the market structure., described in Michael Lewis' bestselling book The Flash Boys. According to the proposal, for the first time, investors will have unified data on metrics, such as the percentage of orders executed, which would show mutual funds whether their transactions were executed on an exchange or in a hidden pool.
