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.
