2. Venue Scorecards (Amended Rule 605)
Execution quality metrics for routed venues benchmarked against mix-adjusted competitors on identical symbols and size tiers.
| Month | Venue | Class | Notional × Lot | Fill Rate | PI Rate | NPI (bps) | Peer Bench (bps) | Coverage | Rank Pctl | Eff Spread | Speed <1s |
|---|
3. Routing-Weighted Composite Quality
Implied execution quality achieved by the firm’s routing mix across the 24 amended size tiers, compared against the best and median competing venues.
| Month | Class | Notional × Lot | Metric | Firm Composite | Best Competing | Best Venue | Median Competing | Mapped Flow |
|---|
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 |
|---|---|---|---|---|---|---|---|---|---|---|

| 202608 | N/A | marketable_limit | 0.0% | 0.00 ¢ | — | — | — | — | — | No conflict |
| 202608 | N/A | nonmarketable_limit | 0.0% | 0.00 ¢ | — | — | — | — | — | No conflict |
| 202608 | N/A | market | 0.0% | 0.00 ¢ | — | — | — | — | — | No conflict |
| 202608 | N/A | marketable_limit | 0.0% | 0.00 ¢ | — | — | — | — | — | No conflict |
| 202608 | N/A | nonmarketable_limit | 0.0% | 0.00 ¢ | — | — | — | — | — | No conflict |
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.
5. Material Changes Since Prior Quarter
Changes in routing share (≥ 5 pp), newly added/dropped venues, and PFOF rate shifts since 2025Q4.
No material shifts (≥ 5 percentage point route share or PFOF rate change) detected relative to 2025Q4.
6. Coverage, Exclusions & Standing Limitations
Mandatory regulatory disclosure of data availability, unmapped destinations, and methodological caveats.

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.
