Could a Market Driven Solution Achieve the Same Goals as the Order Competition Rule without Regulation?

Concept

The core inquiry is whether a market-architected solution, operating without a specific regulatory mandate, can replicate the outcomes intended by the SEC’s Order Competition Rule. The rule itself is a structural intervention, a protocol designed to alter the routing of retail equity orders by forcing them into a competitive auction environment. This protocol interrupts the prevailing system where retail brokers route orders to wholesale market makers in exchange for payment for order flow (PFOF), a practice that concentrates liquidity and execution away from public exchanges. The fundamental goal of the Order Competition Rule is to inject price-setting competition at the level of the individual order, predicated on the analysis that the current level of price improvement offered by wholesalers is suboptimal and represents a “competitive shortfall.”

A purely market-driven solution would need to organically generate this same level of granular, order-by-order competition. This is a significant architectural challenge. The current market structure evolved precisely because of powerful economic incentives. Wholesalers pay for retail order flow because it is, in aggregate, less “toxic” or less likely to be informed by short-term adverse information compared to the institutional order flow present on exchanges.

This allows them to profit from the bid-ask spread while providing some level of price improvement back to the retail client. A market-based alternative must therefore create an incentive structure potent enough to override the economic efficiency of the current PFOF-driven model. It must create a compelling reason for liquidity providers to compete fiercely on price for individual orders, and for brokers to route orders to these competitive venues, even in the absence of a direct mandate.

A market-driven system must construct economic incentives that are powerful enough to replicate the competitive pressures of a mandated auction.

The very existence of the proposed rule suggests that, to date, such a market solution has not spontaneously emerged. The current system, governed by the principle of “Best Execution” under FINRA Rule 5310, requires brokers to use “reasonable diligence” to seek the most favorable price for a customer. Proponents of the Order Competition Rule argue this standard has proven insufficient to prevent market segmentation and the concentration of retail order flow with a few large wholesalers. Therefore, any market-driven alternative must be evaluated on its capacity to produce measurably superior price improvement and transparency, effectively solving the perceived deficiencies of the existing best execution framework without the need for a prescriptive auction mechanism.

Strategy

To evaluate whether a market-driven solution can achieve the goals of the Order Competition Rule, we must dissect and compare the strategic architecture of both approaches. The Order Competition Rule employs a strategy of mandated, centralized competition. In contrast, a market-driven approach would rely on decentralized, incentive-based competition, likely manifesting through several potential structural enhancements. The strategic objective in both cases is identical ▴ maximizing the price improvement available to retail orders by increasing the number of participants bidding for that order flow.

The Mandated Auction Strategy

The strategy of the Order Competition Rule is direct and structural. It identifies a specific class of orders ▴ ”segmented orders” from individual investors ▴ and mandates a change in their routing protocol. Before a wholesaler can internalize such an order, it must be submitted to a “qualified auction” on an open competition trading center, like a registered exchange. This forces the wholesaler’s own potential execution price to compete directly with bids from a wider pool of market participants, including institutional investors and proprietary trading firms who currently have limited access to this order flow.

The strategic assumption is that by forcing interaction between uninformed retail flow and informed professional capital in a structured, time-limited auction (e.g. 300 milliseconds), a more competitive price will be discovered. The regulator is, in essence, acting as a market architect, redesigning the plumbing to force a collision of liquidity that it believes will benefit the retail end-user. The success of this strategy hinges on whether the benefits of increased competition within the auction outweigh the potential costs, such as “quote fade” ▴ the risk that the market price moves adversely during the auction period.

What Are the Market Driven Alternatives?

A market-driven solution would eschew a direct mandate in favor of modifying incentives within the existing market structure. This strategy is more evolutionary than revolutionary, seeking to amplify competitive forces that already exist. Several architectures could facilitate this:

• Enhanced Best Execution Frameworks ▴ This involves a more rigorous and quantitatively defined “Best Execution” standard than the current FINRA rule. Instead of simply requiring “reasonable diligence,” a new framework could mandate that brokers conduct regular and rigorous statistical analysis, perhaps using third-party Transaction Cost Analysis (TCA) providers, to prove their routing decisions yield the maximum possible price improvement. This would force brokers to continuously seek out and route to the most competitive execution venues, creating a commercial incentive for wholesalers and other liquidity providers to offer better prices to attract that flow.
• Expansion of Retail Liquidity Programs (RLPs) ▴ Exchanges already operate RLPs, which are a form of voluntary, on-exchange auction for retail orders. A market-driven strategy could involve making these programs more attractive through fee incentives or by allowing for more sophisticated interaction types. If exchanges can demonstrate that their RLPs consistently provide superior execution to off-exchange internalization, brokers would be compelled by their best execution duty (and client demand) to route more flow to them.
• Competitive Request-for-Quote (RFQ) Systems ▴ The market could develop more sophisticated, broker-operated RFQ systems. In this model, a retail order would trigger an automated, near-instantaneous RFQ sent to a wide range of potential liquidity providers (wholesalers, institutions, etc.). These providers would respond with firm quotes, and the order would be executed against the best price received. This mimics the function of the mandated auction but is a solution developed and operated by market participants in response to competitive pressure.

The core strategic divergence is between a mandated protocol change and the cultivation of an environment where competitive protocols emerge organically.

Comparative Strategic Analysis

We can compare these strategic approaches across several key performance vectors. The table below provides a framework for this analysis, evaluating the mandated auction against a hypothetical enhanced best execution/RFQ model.

Ultimately, the choice between these strategies is a choice between two philosophies of market design. The mandated auction represents a belief that market failures require direct regulatory intervention to correct. The market-driven approach assumes that with the right incentives and performance metrics, competition will naturally produce the desired outcome of superior execution quality.

Execution

The execution of either a mandated or market-driven solution requires a granular understanding of the operational, technological, and quantitative shifts involved. For a financial institution, the difference is profound. A mandated rule imposes a uniform compliance burden, while a market-driven shift necessitates a more dynamic, strategic investment in competitive technology and analytics. Here, we dissect the execution mechanics of both pathways.

Executing the Order Competition Rule a Procedural Blueprint

For a broker-dealer, compliance with the Order Competition Rule is a non-trivial engineering and procedural challenge. The execution process would follow a clear, mandated sequence:

1. Order Classification ▴ Upon receipt, the firm’s Order Management System (OMS) must first classify the order. It must determine if it qualifies as a “segmented order” based on the SEC’s definition (i.e. from a natural person’s account with trading activity below a certain threshold). This requires integrating account data with the order entry workflow.
2. Internal Pricing Check ▴ The system must check for exceptions. Can the order be executed at or better than the midpoint of the National Best Bid and Offer (NBBO)? If so, it may be exempt from the auction. This requires a real-time feed of NBBO data and immediate price comparison logic.
3. Auction Parameterization ▴ If the order is not exempt, the wholesaler or executing venue must determine the limit price at which to submit the order to a qualified auction. This price becomes the floor for the auction. The order is then packaged with the required parameters for the auction mechanism.
4. Routing to a Qualified Auction ▴ The firm’s Smart Order Router (SOR) must be reconfigured. It needs to identify and maintain connections to all “open competition trading centers” operating qualified auctions. The order is then routed to one of these venues.
5. Monitoring and Fallback ▴ The system must monitor the order for the duration of the auction (e.g. 300 milliseconds). If the order is fully or partially filled, the execution report is processed. If it is unfilled, the fallback protocol is initiated, and the wholesaler is then permitted to internalize the order at its pre-determined price.

Executing a Market-Driven Solution the TCA-Centric Workflow

A market-driven solution places the execution burden squarely on the broker-dealer’s best execution process. The core operational tool becomes the Transaction Cost Analysis (TCA) report. The workflow is cyclical and data-intensive.

How Would a Broker-Dealer Adapt?

The broker-dealer’s process shifts from rule-based compliance to continuous, evidence-based optimization. The firm’s “Best Execution Committee” would be at the center of this process, overseeing a quarterly, or even monthly, “regular and rigorous” review as required by FINRA.

This review is no longer a qualitative check. It becomes a quantitative analysis of routing performance. The table below illustrates what a simplified TCA comparison might look like, comparing different execution venues for a specific class of orders (e.g. retail market orders in high-volume ETFs).

In this scenario, the data suggests that while Wholesaler A provides fast executions, the actual price improvement is lower than that available on Exchange RLP C or the firm’s own experimental RFQ network. The “Effective Spread Capture” metric shows how much of the bid-ask spread is being returned to the client as price improvement. The negative “Reversion” for the wholesalers indicates the price tended to move further in the client’s favor after the trade, suggesting they could have received an even better price.

Armed with this data, the Best Execution Committee would be compelled to adjust the SOR logic, shifting more flow to the RLP and investing more in its RFQ technology to achieve a demonstrably better outcome for clients. This data-driven feedback loop is the engine of a market-based solution; competition is fostered not by mandate, but by the relentless, quantifiable pursuit of better execution statistics.

Reflection

The analysis of mandated competition versus market-driven solutions presents a fundamental question about the architecture of trust in financial markets. Does an institution place greater faith in a system defined by explicit regulatory protocols, or in one shaped by the pressures of quantifiable, performance-based competition? The Order Competition Rule offers a clear, if rigid, pathway toward a specific definition of fairness. It is an attempt to hard-code competition into the market’s operating system.

A market-driven framework, however, demands a different kind of institutional capability. It requires a commitment to building and maintaining a superior intelligence layer ▴ an internal system of analytics, routing logic, and continuous evaluation that can navigate a complex and dynamic execution landscape. The goal shifts from compliance with a static rule to the perpetual pursuit of a competitive edge. The question for any market participant is therefore not simply which system is better, but which system is your own operational framework built to master?
