## Concept

The removal of the prescriptive RTS 28 reporting requirement does not dissolve the fundamental duty of [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite); it intensifies it. The regulatory focus pivots from a standardized, and often unread, reporting template to a more profound, principles-based validation of a firm’s internal processes. Demonstrating compliance now requires the construction of a coherent and defensible evidence architecture.

This system must prove that a firm is taking all sufficient steps to consistently secure the most favorable terms for its clients. The absence of a rigid reporting format elevates the importance of the firm’s own [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), transforming it from a static compliance document into the central pillar of a dynamic, evidence-generating framework.

This framework rests upon the foundational execution factors that persist regardless of specific regulations ▴ price, costs, speed, and the likelihood of execution and settlement. However, the evidential burden moves beyond simply acknowledging these factors. It demands a system that can articulate, for any given trade, why a particular execution strategy and venue selection were optimal under the prevailing market conditions.

This requires a qualitative narrative supported by quantitative data. The core task is to create a verifiable audit trail that connects the firm’s high-level execution policy to the specific outcome of each client order, demonstrating a consistent and intelligent application of its stated principles.

> The core challenge shifts from standardized reporting to demonstrating the robustness of the internal execution and decision-making framework.

## The Pillars of Demonstrable Compliance

In this environment, evidence becomes a mosaic of [qualitative governance](https://prime.greeks.live/area/qualitative-governance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and quantitative analysis. The integrity of this mosaic depends on the firm’s ability to systematically capture and connect different forms of proof. A firm’s compliance is judged not by a single report, but by the quality and interplay of its entire execution ecosystem.

- **The Execution Policy as a Constitution** ▴ This document is the foundational piece of evidence. It must be a living document that clearly defines the firm’s approach to achieving best execution, including the relative importance of different execution factors for various client types and financial instruments. 

- **Systematic Pre-Trade Analysis** ▴ Evidence must show that execution strategies are considered before an order is routed. This includes documentation of [venue analysis](https://prime.greeks.live/area/venue-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), algorithmic strategy selection, and the rationale for choosing a particular execution pathway.

- **Verifiable Post-Trade Scrutiny** ▴ This involves the systematic analysis of [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) against defined benchmarks. It is the quantitative proof that the firm’s policies and pre-trade decisions are effective in practice.

- **Robust Governance and Oversight** ▴ Demonstrating compliance requires evidence of active human oversight. This includes minutes from best execution committees, records of policy reviews, and documentation of how the firm addresses any identified deficiencies in its execution arrangements.

## Strategy

A strategic approach to demonstrating best execution compliance in a post-RTS 28 world involves architecting a Defensible Evidence Framework. This framework is a deliberate system designed to generate a comprehensive and cohesive body of proof. It integrates qualitative judgments with quantitative data, ensuring that every aspect of the trading lifecycle contributes to a verifiable compliance narrative. The objective is to move from a reactive, document-gathering exercise to a proactive system where robust evidence is the natural output of a superior execution process.

The strategy is built on two interconnected layers ▴ the Qualitative Governance Layer and the Quantitative Measurement Layer. The first establishes the ‘intent’ ▴ the firm’s documented policies, procedures, and oversight mechanisms. The second provides the ‘proof’ ▴ the empirical data that validates the effectiveness of that intent.

A regulator’s inquiry will probe the linkage between these two layers. A strong strategy ensures that the story told by the governance documents is confirmed by the execution data.

## The Qualitative Governance Layer

This layer comprises the documented rationale behind the firm’s execution decisions. It is the evidence of diligence, forethought, and control. The strength of this layer is determined by its clarity, specificity, and the rigor of its application. It must provide a clear answer to the question ▴ “How does your firm ensure it is set up to achieve the best possible results for its clients?”

## Key Evidentiary Components

- **Execution Policy Detail** ▴ The policy must go beyond generic statements. It should detail how execution strategies differ across asset classes, order types, and client classifications. For instance, it should specify when ‘price’ is the dominant factor versus when ‘likelihood of execution’ for an illiquid instrument takes precedence. 

- **Venue and Broker Analysis** ▴ Firms must maintain and evidence a systematic process for evaluating and selecting execution venues and brokers. This includes due diligence documentation, performance reviews against stated criteria (e.g. fill rates, latency, cost), and a clear rationale for the inclusion of each venue in the firm’s routing logic.

- **Governance Committee Records** ▴ The minutes and presentation materials from [Best Execution Committee](https://prime.greeks.live/area/best-execution-committee/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) meetings are critical evidence. They must demonstrate active oversight, including reviews of [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) reports, discussions of any execution issues, and decisions made to modify execution arrangements or policies. 

- **Documentation of Changes** ▴ Any modification to the execution policy or routing arrangements must be documented, including the date of the change, the reason for the change, and the expected benefit. This demonstrates an adaptive and responsive compliance culture.

## The Quantitative Measurement Layer

This layer provides the empirical validation of the firm’s execution policy. It relies on systematic [Transaction Cost](https://prime.greeks.live/area/transaction-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Analysis (TCA) to measure the quality of execution against objective benchmarks. Without the prescriptive format of RTS 28, the onus is on the firm to select and justify the appropriateness of its chosen metrics and analytical methods. The central piece of evidence here is not just the data, but the analysis and interpretation of that data.

> Effective compliance is evidenced by a clear, auditable link between the firm’s stated execution policy and its measured trading outcomes.

The table below outlines key TCA benchmarks that form the core of the quantitative evidence base. A firm must be able to produce reports using these, or similarly robust, metrics and explain why they are relevant for the types of orders being analyzed.

| TCA Benchmark | Description | Evidentiary Purpose |
| --- | --- | --- |
| Implementation Shortfall (IS) | Measures the total cost of executing an order against the price at the moment the investment decision was made (the ‘arrival price’). It captures market impact, delay costs, and explicit fees. | Provides the most comprehensive view of execution quality, demonstrating the total cost incurred by the trading process itself. It is the gold standard for evidencing performance against the ‘total cost’ principle. |
| Volume-Weighted Average Price (VWAP) | Compares the average price of a firm’s execution to the average price of all trades in the market for that security over a specific period. | Demonstrates the ability to execute in line with market liquidity. It is useful for evidencing performance for less urgent, passive orders where minimizing market impact is a key objective. |
| Time-Weighted Average Price (TWAP) | Compares the average execution price to the average price of the security over the order’s lifetime. | Evidences performance for orders that are worked over a specific time horizon, demonstrating that the execution was representative of the prices available during that period. |
| Reversion Analysis | Analyzes the price movement of a security immediately after a trade is executed. A significant price reversion may indicate market impact. | Provides evidence that the firm’s trading activity is not unduly impacting market prices, which is a key component of achieving a favorable result for the client. |

## Execution

The execution of a best execution compliance framework, absent RTS 28, is an exercise in operationalizing a continuous cycle of policy, measurement, review, and refinement. It requires building a robust internal system where the generation of evidence is not an afterthought but an integral part of the daily workflow. This system must be capable of capturing granular trade data, contextualizing it within the firm’s policies, and presenting it in a manner that is clear, defensible, and demonstrates active management of execution quality.

The focus moves from producing a static annual report to maintaining a dynamic, auditable ecosystem. This ecosystem must prove that the firm’s Best [Execution Committee](https://prime.greeks.live/question/how-does-a-best-execution-committee-quantify-and-compare-execution-quality-across-different-venues/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is not just a formality, but an effective governing body that uses concrete data to inform its oversight and decision-making. The ultimate goal is to create a closed-loop system where quantitative analysis informs qualitative judgment, leading to demonstrable improvements in execution outcomes.

## The Operational Cadence of the Best Execution Committee

A central pillar of the evidential framework is the Best Execution Committee. The documentation produced by this committee is a primary source of proof that the firm takes its obligations seriously. To be effective, the committee’s operations must follow a structured and repeatable cadence.

- **Scheduled Meetings with a Fixed Agenda** ▴ The committee should meet at regular intervals (e.g. quarterly) with a standardized agenda. This agenda must be documented and should always include a review of TCA reports, an analysis of any execution policy exceptions, a discussion of venue performance, and a formal sign-off on the minutes of the previous meeting.

- **The Pre-Meeting Information Pack** ▴ Prior to each meeting, a comprehensive information pack must be distributed to all members. This pack is a critical piece of evidence and should contain the TCA dashboards, reports on broker and venue performance, a log of any client complaints related to execution, and a summary of any market structure changes that could impact the firm’s execution policy.

- **Rigorous Minute-Taking** ▴ The minutes of the meeting are arguably the most important qualitative evidence. They must go beyond a simple summary of discussions. They need to document challenges, decisions, and action items with assigned owners and deadlines. For example, if the TCA report shows consistent underperformance for a particular type of order, the minutes must reflect the committee’s discussion of the issue and the steps it has decided to take to investigate and remediate it.

- **Action Item Tracking and Closure** ▴ A formal log of action items must be maintained. This log provides a clear audit trail of the committee’s effectiveness, showing how identified issues are tracked, addressed, and resolved over time. This demonstrates an active, rather than passive, approach to compliance.

## The Best Execution Monitoring Dashboard

The foundation of the committee’s work is a detailed monitoring dashboard that provides a consolidated view of execution quality. This dashboard is the primary source of quantitative evidence. It must be configurable to allow for analysis across different dimensions (e.g. by asset class, client type, venue, or trader).

The table below provides a simplified example of what such a dashboard might contain for a sample of trades. The ability to produce, interpret, and act upon this data is at the heart of demonstrating compliance.

| Order ID | Asset Class | Venue | Execution Price | Arrival Price | Implementation Shortfall (bps) | Qualitative Flag |
| --- | --- | --- | --- | --- | --- | --- |
| 7465A | Equity | Venue A | 100.05 | 100.02 | +3.0 | Within expected range |
| 7466B | Equity | Venue B | 55.12 | 55.05 | +12.7 | Exception – Review Required |
| 8912C | Fixed Income | Broker X | 99.85 | 99.88 | -3.0 | Positive Slippage |
| 9133D | FX | Platform Y | 1.1234 | 1.1233 | +0.9 | Within expected range |

> A defensible framework is evidenced by the clear, documented process for reviewing quantitative outliers and taking corrective action.

The “Qualitative Flag” column is a crucial link between the quantitative data and the qualitative governance process. An “Exception” flag would automatically trigger a review process. The evidence for this process would include a documented investigation into the trade (e.g. was it a large, illiquid order in a volatile market?), the conclusion of that investigation, and any remedial action taken. This creates a powerful, closed-loop system of evidence that is far more meaningful than a static, aggregated report.

## From Obligation to Intelligence

Moving beyond a prescriptive reporting standard presents an opportunity to reframe the concept of best execution. The mandate transforms from a compliance task, focused on the production of a standardized artifact, into the development of an internal intelligence system. The evidence required is no longer a snapshot but a continuous data stream, contextualized by a clear governance narrative. This system, built to prove compliance, simultaneously provides the analytical tools to refine and enhance execution strategy.

The framework necessary for demonstrating adherence to the [best execution policy](https://prime.greeks.live/area/best-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) inherently creates a powerful feedback loop. The transaction [cost analysis](https://prime.greeks.live/area/cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) reports, the venue performance reviews, and the exception logs are the raw materials for strategic improvement. By analyzing this data, a firm can identify subtle inefficiencies in its routing logic, discover superior liquidity sources, and optimize its algorithmic trading strategies. The process of gathering evidence becomes a mechanism for gaining a competitive edge.

Ultimately, the question of evidence should lead to a deeper introspection of a firm’s operational philosophy. Is the execution process viewed as a cost center to be managed, or as a source of alpha to be cultivated? A robust evidential framework does more than satisfy a regulator; it provides a detailed, data-driven map of a firm’s interaction with the market. Mastering this data is the foundation of mastering execution itself.
