Methodological Caveats:

  • A venue's Rule 605 statistics describe all flow it handled, not this firm's orders.
  • 606 route shares are per order, not per share, and list only the top 10 venues plus any venue with at least 5% of non-directed orders.
  • FINRA Rule 5310.09 also requires the firm's own order-level review of its executions.
  • This report is not legal or compliance advice.
  • Net price improvement is in basis points of executed notional (quote midpoint × shares). The PFOF comparison converts the difference to ¢/100 sh at the venue's average executed price; it is an estimate.
  • Brokers routing here reflect venue aliases as of the last crosswalk-venues run.
