The Securities and Exchange Commission’s Rule 605 (formerly 11Ac1-5) mandates that stock exchanges, dealers, and other market centers provide selected data on selected order executions.
Please note that this information may not be directly comparable to data displayed by other market centers due to differences in market structures and computation methods. SEC-required data does not account for quoted depth in spread calculations, the economic impact of order flow payment on brokerage customers, the costs of institutional trading, or the many criteria that encompass a cost-effective order routing strategy.
