## Concept

A firm’s [best execution policy](https://prime.greeks.live/area/best-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) document is the central schematic for its entire [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) apparatus. Regulators approach this document not as a static disclosure but as the definitive architectural plan of the firm’s trading operations. It must codify the precise logic and control systems the firm employs to ensure client orders are handled with the highest degree of diligence. The expectation is that this documentation provides a transparent, verifiable, and replicable account of how the firm systematically pursues the most favorable terms reasonably available for its clients under the prevailing market conditions.

This process begins with a foundational understanding of the duty of [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), an obligation derived from common law agency principles and fiduciary responsibilities. It compels a broker-dealer to exercise reasonable diligence in seeking the best market and executing transactions at a price that is as advantageous as possible for the customer. The [policy document](https://prime.greeks.live/question/how-should-a-buy-side-firms-best-execution-policy-document-the-use-of-systematic-internalisers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) serves as the primary evidence of this diligence.

It is the tangible manifestation of the firm’s commitment, transforming an abstract legal duty into a concrete, auditable operational framework. Regulators scrutinize this document to see a clear, logical line from the firm’s stated policies to its actual order handling practices and, ultimately, to the execution outcomes delivered to clients.

> The best execution policy is the firm’s documented proof of its systematic process for achieving optimal client outcomes in prevailing market conditions.

The scope of this regulatory expectation is comprehensive, applying to any firm that receives customer orders for handling and execution. This includes firms taking orders directly from clients as well as wholesale market makers that receive orders from other broker-dealers. The responsibility is non-transferable; a firm cannot delegate its best execution duty to another entity.

Consequently, firms that route all their customer orders to another broker-dealer must still conduct an independent review of the execution quality received and document this process within their policy. The document must therefore detail the specific procedures for this oversight, demonstrating that the firm is not merely a passive conduit but an active guardian of its clients’ interests.

At its core, the policy must articulate the firm’s methodology for evaluating execution quality. This involves a nuanced assessment of multiple “execution factors.” While price is a primary consideration, regulators expect a holistic analysis that also incorporates the speed of execution, the likelihood of execution and settlement, and the size and nature of the order. The policy must define the relative importance of these factors, justifying how the firm weighs them based on the specific characteristics of the client, the order, and the financial instruments involved. This documented rationale is critical, as it provides regulators with insight into the firm’s decision-making calculus and its ability to adapt its approach to varying market scenarios and client needs.

## Strategy

Developing a strategic framework for a best [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) requires a firm to move beyond mere compliance and establish a robust governance structure. This structure is built upon a clear articulation of how the firm will conduct its reviews of execution quality. The choice between an order-by-order review and a “regular and rigorous” periodic review is a primary strategic decision that dictates the operational and documentary workflow.

While an order-by-order review provides the most granular level of scrutiny, a periodic review process is permissible if the firm implements and documents a systematic approach to assessing execution quality over time. This strategic choice must be explicitly stated and justified within the policy, outlining the methodology, frequency, and data sources used for the review.

## Defining the Review and Governance Framework

A cornerstone of the policy’s strategy is the establishment of a formal, documented review process. Under proposed [SEC Regulation Best Execution](https://prime.greeks.live/area/sec-regulation-best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), firms would be required to review their policies and procedures at least annually and present a detailed report of their findings to their board of directors or an equivalent governing body. This elevates the best execution policy from a simple operational document to a matter of formal corporate governance.

The policy must, therefore, outline the mechanics of this annual review, including who is responsible for conducting it, the scope of the assessment, and the format of the report to be delivered to the board. This documented governance process demonstrates to regulators that best execution is a priority that receives senior management attention and oversight.

Furthermore, the strategy must account for more frequent, tactical reviews of execution quality. Proposed rules mandate at least a quarterly review of execution quality, comparing the firm’s results with the quality that might have been obtained from other markets. The policy must detail the procedures for these quarterly assessments.

This includes specifying the benchmarks and data sources that will be used for comparison, the process for identifying and analyzing any deficiencies, and the mechanism for implementing corrective actions. The documentation of these quarterly reviews serves as a continuous, running record of the firm’s diligence and its responsiveness to changing market conditions.

> A firm’s policy must strategically define its review methodology, whether on an order-by-order basis or through regular, rigorous assessments.

## Addressing Conflicted Transactions and Order Flow

A critical component of a best execution policy’s strategy is its approach to managing conflicts of interest, particularly in the context of [conflicted transactions](https://prime.greeks.live/area/conflicted-transactions/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Proposed regulations place heightened obligations on firms engaging in transactions where the firm has a conflict, such as principal trading, routing orders to an affiliated broker-dealer, or receiving [payment for order flow](https://prime.greeks.live/area/payment-for-order-flow/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (PFOF). The policy must contain a distinct section with additional procedures for these scenarios. The documentation must be sufficiently detailed to prove that the firm is still achieving the best possible outcome for the client, even in the presence of a conflict.

For example, the policy must describe how the firm will document its compliance with the best execution standard for conflicted transactions. This could involve retaining records of prices checked at competing markets, documenting attempts to execute at prices better than the National Best Bid and Offer (NBBO), and ensuring that any [price improvement](https://prime.greeks.live/area/price-improvement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) offered is consistent across all clients, regardless of PFOF arrangements. The strategic imperative is to create a documentary trail that preemptively answers any regulatory questions about whether a conflict has compromised the firm’s duty to its client.

The following table outlines strategic considerations for documenting different types of review processes:

| Review Type | Key Strategic Considerations | Documentation Focus | Regulatory Emphasis |
| --- | --- | --- | --- |
| Order-by-Order Review | Feasibility for the firm’s business model and order flow volume. Technology requirements for real-time analysis. Defining “most favorable terms” on a per-trade basis. | Timestamped records of each order’s lifecycle. Documentation of alternative venues considered at the time of the trade. Rationale for the chosen execution path for each specific order. | Demonstrating diligence at the most granular level. Justifying the execution outcome for each individual client transaction. |
| Regular and Rigorous Review | Defining the frequency (e.g. quarterly) and scope of the review. Selecting appropriate execution quality statistics (e.g. price improvement, effective spread). Establishing a formal committee or group responsible for the review. | Aggregated data on execution quality across different venues. Comparative analysis against benchmark venues. Minutes and reports from the review committee detailing findings and actions taken. | The systematic and consistent application of the review process. Evidence that the review leads to meaningful changes in order routing practices. |
| Conflicted Transaction Review | Identifying all potential conflicts (PFOF, principal trading, affiliate routing). Establishing heightened procedures for these transactions. Ensuring no disadvantage to the client. | Specific documentation of compliance for each conflicted trade. Records of alternative quotes sought. Analysis showing that the conflicted execution was still the most favorable reasonably available. | Proving that the conflict of interest did not harm the client’s execution. Transparency regarding the nature and management of the conflict. |

## Execution

The execution of a best execution policy document is a matter of meticulous detail and procedural clarity. Regulators expect a document that is not only comprehensive in scope but also practical in its application. It should function as an operational manual for the firm’s personnel and a transparent guide for auditors and examiners.

The document must be structured logically, with clear sections that address all facets of the firm’s best execution obligations. This includes defining the core principles, detailing the review processes, and outlining the governance and record-keeping protocols.

## Core Components of the Policy Document

A robust best execution policy document must be meticulously structured to provide a comprehensive overview of the firm’s approach. The following components are essential for creating a document that meets regulatory expectations:

- **Introduction and Scope** ▴ This section should clearly state the firm’s commitment to achieving best execution for its clients. It must define the scope of the policy, specifying the types of clients, orders, and financial instruments it covers.

- **Execution Factors and Their Relative Importance** ▴ The policy must explicitly list the execution factors the firm considers. These typically include price, costs, speed, likelihood of execution, and settlement, as well as the size and nature of the order. Crucially, it must explain the process by which the firm determines the relative importance of these factors for different types of orders and clients.

- **Order Handling and Routing Practices** ▴ This section forms the operational core of the document. It must describe the firm’s procedures for handling and routing client orders. This includes details on the firm’s use of different execution venues (e.g. national exchanges, alternative trading systems, market makers) and the criteria used to select them.

- **Procedures for “Regular and Rigorous” Review** ▴ For firms not conducting an order-by-order review, this section is paramount. It must detail the methodology for the periodic review of execution quality. This includes the frequency of the review (at least quarterly), the data and metrics used (e.g. effective spreads, price improvement statistics), the process for comparing execution quality against other venues, and the procedures for addressing any identified deficiencies.

- **Special Procedures for Conflicted Transactions** ▴ A dedicated section must address the handling of conflicted transactions. This includes defining what constitutes a conflict for the firm and outlining the specific, heightened procedures in place to ensure best execution is still achieved. It should also detail the additional documentation required for these trades.

- **Governance, Oversight, and Annual Report** ▴ The policy must describe the [governance framework](https://prime.greeks.live/area/governance-framework/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) surrounding best execution. This includes identifying the individuals or committees responsible for oversight and outlining the process for the annual review and the subsequent report to the board of directors.

- **Record-Keeping** ▴ This section should specify the records that will be created and maintained to demonstrate compliance with the policy. This includes the results of quarterly and annual reviews, documentation of [order routing](https://prime.greeks.live/area/order-routing/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) decisions, and any analysis related to conflicted transactions.

## Documenting the Review Process in Practice

The documentation of the firm’s “regular and rigorous” review is a focal point for regulatory scrutiny. A firm must be able to produce tangible evidence of these reviews. This evidence should demonstrate a systematic and analytical approach to evaluating execution quality. A key element of this is the comparative analysis of execution venues.

The following table provides a simplified example of how a firm might document a portion of its quarterly [execution quality review](https://prime.greeks.live/area/execution-quality-review/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for a specific security:

| Execution Venue | Total Shares Executed | Avg. Price Improvement (per share) | Avg. Effective Spread (cents) | Fill Rate (%) | Notes / Action Items |
| --- | --- | --- | --- | --- | --- |
| Internalized Flow | 1,500,000 | $0.0015 | 0.85 | 100% | Price improvement is consistent. Continue monitoring effective spread relative to Venue B. |
| Venue A (Exchange) | 750,000 | N/A | 1.10 | 98.5% | Higher effective spread. Review order types used on this venue to optimize for spread capture. |
| Venue B (ATS) | 500,000 | $0.0005 | 0.80 | 95.2% | Lowest effective spread but lower fill rate. Investigate causes of unfilled orders. |
| Venue C (Wholesaler) | 250,000 | $0.0018 | 0.90 | 100% | Highest price improvement. Consider routing a larger portion of non-marketable limit orders here. |

> The policy document must translate abstract duties into concrete, auditable procedures and governance structures.

This documented analysis is the foundation for any subsequent changes to the firm’s order routing logic. The policy must stipulate that the findings of such reviews are used to revise and enhance order handling practices. The firm must be able to show a clear link between its analysis of execution quality data and its decisions about where to route client orders. This creates a feedback loop, where the firm continuously monitors its performance, identifies areas for improvement, and adjusts its systems accordingly, with the entire process being thoroughly documented for regulatory review.

## The Policy as a Living System

Ultimately, the documentation of a best execution policy should be viewed not as a task to be completed, but as the maintenance of a living system. It is the codified intelligence of the firm’s trading apparatus, a system that must adapt to new market structures, evolving technologies, and changing regulatory landscapes. The true test of a policy is not its length or the complexity of its language, but its functional integrity. Does it provide a clear and defensible rationale for every order routing decision?

Does it create a verifiable feedback loop where performance is measured, analyzed, and used to drive improvement? A policy that achieves this becomes more than a compliance document; it is a strategic asset, a framework for operational excellence that embeds the principle of client priority into the very architecture of the firm.
