4. Payment for Order Flow vs. Execution Quality

Addresses FINRA 5310.09 conflicts: comparing PFOF received (¢/100 sh) against net price improvement shortfall vs mix-adjusted peers.

Month	Venue	Order Class	Route %	606 Net PFOF (¢/100)	NPI (bps)	Peer Bench (bps)	Delta (bps)	Ref Price	Delta (¢/100 sh)	Conflict Flag

Conflict Methodology Note: Quality delta (¢/100 sh) is estimated as Δ_bps × ref_price. A positive PFOF beside a negative delta indicates the firm received payment while the venue delivered less price improvement than competing market centers on identical symbols and size tiers.

Standing Review Limitations:

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.
