## Concept

The Markets in [Financial Instruments](https://prime.greeks.live/area/financial-instruments/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Directive II (MiFID II) defines best execution as an obligation for firms to take [all sufficient steps](https://prime.greeks.live/area/all-sufficient-steps/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to obtain the best possible result for their clients when executing orders. This directive expands upon its predecessor, MiFID I, by demanding a more rigorous and demonstrable approach to achieving this outcome. The framework moves beyond a simple consideration of price to encompass a variety of execution factors.

These factors include costs, speed, likelihood of execution and settlement, size, and the nature of the order itself. The directive’s core purpose is to enhance [investor protection](https://prime.greeks.live/area/investor-protection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), preserve the integrity of the price formation process, and foster competition among trading venues in increasingly fragmented markets.

A key element of MiFID II is the requirement for investment firms to establish and implement a comprehensive [order execution policy](https://prime.greeks.live/area/order-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This policy must be detailed and transparent, outlining for each class of [financial instrument](https://prime.greeks.live/area/financial-instrument/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) the different venues where client orders are executed and the factors that influence the choice of venue. For retail clients, the best possible result is determined primarily by total consideration, which is the price of the financial instrument combined with all execution-related costs.

This includes fees from the [execution venue](https://prime.greeks.live/area/execution-venue/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), as well as clearing and settlement fees. The policy must be easily understandable to clients, explaining clearly how their orders will be executed.

> MiFID II mandates that firms do more than just seek the best price; they must build a verifiable system that consistently delivers the best overall outcome for their clients across a range of influencing factors.

The directive also introduces stringent transparency requirements. [Execution venues](https://prime.greeks.live/area/execution-venues/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), including market makers and liquidity providers, are required to publicly disclose data on [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) at no charge. This allows for greater scrutiny and comparison of execution quality across different venues.

Furthermore, investment firms that execute [client orders](https://prime.greeks.live/area/client-orders/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) must publicly report annually on their top five execution venues by volume for each class of financial instrument, along with an analysis of the execution quality obtained. This public reporting fosters accountability and allows clients to assess the effectiveness of their firm’s [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## What Are the Core Principles of Best Execution?

The core principles of best [execution under MiFID](https://prime.greeks.live/question/what-are-the-specific-data-reporting-requirements-for-execution-venues-under-mifid-ii-rts-27/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) II are rooted in the obligation to act in the client’s best interest. This is achieved through a systematic approach that considers multiple factors to achieve the optimal outcome. The principles can be summarized as follows:

- **All Sufficient Steps** ▴ Firms must take all sufficient steps, a higher standard than the “all reasonable steps” required under MiFID I, to achieve the best [possible result](https://prime.greeks.live/guide/price-control-is-possible-if-you-know-the-right-method/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for their clients. This implies a more proactive and evidence-based approach to [order execution](https://prime.greeks.live/area/order-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

- **Multi-faceted Analysis** ▴ The best possible result is not solely determined by price. Firms must consider a range of [execution factors](https://prime.greeks.live/area/execution-factors/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), including costs, speed, likelihood of execution and settlement, size, and the nature of the order. The relative importance of these factors may vary depending on the client’s objectives and the specific characteristics of the order.

- **Transparency and Disclosure** ▴ Firms are required to provide clients with clear and detailed information about their order execution policies. This includes disclosing the execution venues used and the factors influencing their selection. Annual public reporting on the top five execution venues and the quality of execution obtained is also mandatory.

- **Continuous Monitoring and Review** ▴ Firms must regularly monitor the effectiveness of their order execution arrangements and policies. This includes both ex-ante monitoring, such as reviewing the design of policies, and ex-post monitoring, such as checking if the firm has correctly applied its execution policy. Execution policies must be reviewed at least annually and whenever a material change occurs that could affect the firm’s ability to obtain the best possible result.

## Strategy

Developing a robust best [execution strategy](https://prime.greeks.live/area/execution-strategy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) [under MiFID](https://prime.greeks.live/question/what-are-the-specific-data-reporting-requirements-for-execution-venues-under-mifid-ii-rts-27/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) II requires a systematic and data-driven approach. It involves creating a framework that not only complies with the regulations but also provides a competitive advantage by consistently delivering superior execution quality for clients. A successful strategy is built on a deep understanding of the available execution venues, a rigorous process for selecting them, and a commitment to continuous improvement through monitoring and analysis.

## Formulating an Effective Order Execution Policy

The order execution policy is the cornerstone of a firm’s [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) strategy. It is a formal document that articulates how the firm will meet its best execution obligations. The policy should be tailored to the firm’s specific business model, client base, and the types of financial instruments it trades. Key components of an [effective order execution policy](https://prime.greeks.live/question/what-are-the-practical-challenges-of-implementing-a-mifid-ii-compliant-order-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) include:

- **Scope and Application** ▴ The [policy should](https://prime.greeks.live/question/how-should-a-best-execution-policy-adapt-to-the-rise-of-systematic-internalizers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) clearly define its scope, specifying the clients and financial instruments to which it applies. [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s best execution requirements apply to both retail and professional clients and cover a wide range of financial instruments, including equities, bonds, derivatives, and structured finance products.

- **Execution Factors and Their Relative Importance** ▴ The policy must detail the execution factors that the firm will consider when executing client orders. These factors typically include price, costs, speed, likelihood of execution, and size of the order. The policy should also explain the relative importance assigned to each factor, which may vary depending on the client’s categorization (retail or professional) and the specific instructions provided.

- **Execution Venues** ▴ The policy must list the execution venues that the firm uses for each class of financial instrument. This list should be comprehensive and include [regulated markets](https://prime.greeks.live/question/can-a-single-block-order-be-partially-filled-on-a-regulated-market-and-an-si-simultaneously/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), multilateral trading facilities (MTFs), organised trading facilities (OTFs), and systematic internalisers. The policy should also explain the criteria used to select these venues.

- **Monitoring and Review** ▴ The policy should outline the processes for monitoring and reviewing the effectiveness of the firm’s execution arrangements. This includes both internal monitoring of execution quality and the regular review of the execution policy itself to ensure it remains up-to-date and effective.

## Selecting and Managing Execution Venues

The selection and management of execution venues are critical components of a best execution strategy. With a multitude of trading venues available, firms must have a systematic process for evaluating and choosing the venues that are most likely to deliver the best results for [their clients](https://prime.greeks.live/question/how-can-technology-be-leveraged-to-streamline-enhanced-due-diligence-requirements-for-clients/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This process should be data-driven and based on a thorough analysis of each venue’s performance.

The following table provides a comparison of different types of execution venues:

| Venue Type | Description | Key Characteristics | Best Suited For |
| --- | --- | --- | --- |

> A diversified approach to venue selection, tailored to the specific characteristics of each order, is essential for achieving best execution in today’s fragmented market landscape.

## How Can Firms Leverage Technology for Best Execution?

Technology plays a pivotal role in enabling firms to meet their best execution obligations under MiFID II. Advanced trading technologies can help firms to automate and optimize their [order routing](https://prime.greeks.live/area/order-routing/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) processes, access a wider range of liquidity sources, and monitor execution quality in real-time. Key technologies that can be leveraged for best execution include:

- **Smart Order Routers (SORs)** ▴ SORs are algorithms that automatically route orders to the execution venue that is most likely to provide the best outcome based on a predefined set of rules. These rules can be configured to prioritize different execution factors, such as price, speed, or likelihood of execution.

- **[Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA)** ▴ TCA is a set of tools and techniques used to measure the costs associated with trading. By analyzing TCA data, firms can identify opportunities to improve their execution performance and reduce trading costs.

- **Execution Management Systems (EMS)** ▴ An EMS is a software platform that provides traders with a consolidated view of the market and a suite of tools for managing and executing orders. A sophisticated EMS can integrate with multiple liquidity sources, provide access to advanced order types, and offer real-time analytics on execution quality.

## The Operational Playbook for Best Execution

An [operational playbook](https://prime.greeks.live/area/operational-playbook/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for best execution should provide a step-by-step guide to the processes and procedures that need to be followed to ensure compliance with MiFID II. The playbook should be a living document that is regularly updated to reflect changes in the regulatory landscape, market structure, and the firm’s own business model. The following is a high-level outline of an operational playbook for best execution:

- **Establish a Governance Framework** ▴ The first step is to establish a clear governance framework for best execution. This includes defining roles and responsibilities, establishing a best execution committee, and creating a formal process for the approval and review of the order execution policy.

- **Develop a Data-Driven [Venue Selection](https://prime.greeks.live/area/venue-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Process** ▴ The selection of execution venues should be based on a rigorous and data-driven analysis of their performance. This involves collecting and analyzing data on a range of metrics, including execution prices, costs, speed, and fill rates. The results of this analysis should be used to create a preferred list of execution venues for each class of financial instrument.

- **Implement a [Smart Order Routing](https://prime.greeks.live/area/smart-order-routing/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Strategy** ▴ A smart order routing (SOR) strategy is essential for optimizing order execution in a fragmented market. The SOR should be configured to route orders to the venue that is most likely to provide the best outcome based on the specific characteristics of the order and the firm’s best execution policy.

- **Conduct Regular [Transaction Cost](https://prime.greeks.live/area/transaction-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Analysis (TCA)** ▴ Transaction [cost analysis](https://prime.greeks.live/area/cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) is a critical tool for monitoring and improving execution performance. Firms should conduct regular TCA to measure their trading costs against benchmarks and identify areas for improvement. The results of the TCA should be used to refine the SOR strategy and the venue selection process.

- **Produce and Publish [RTS 28](https://prime.greeks.live/area/rts-28/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Reports** ▴ MiFID II requires firms to publish an annual report on their top five execution venues for each class of financial instrument (RTS 28). This report must include information on the quality of execution obtained at each venue. The process for producing and publishing this report should be clearly defined in the operational playbook.

## Quantitative Modeling and Data Analysis

Quantitative modeling and data analysis are at the heart of a modern best execution framework. By leveraging data and advanced analytical techniques, firms can gain deep insights into their execution performance and make more informed decisions about how to route their orders. A key aspect of this is the analysis of execution quality data, both from internal sources and from the public reports published by execution venues ([RTS 27](https://prime.greeks.live/area/rts-27/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)).

The following table provides a simplified example of the type of data that might be included in an RTS 28 report for a specific class of financial instrument:

| Execution Venue | Proportion of Volume | Proportion of Orders | Percentage of Passive Orders | Percentage of Aggressive Orders | Likelihood of Execution |
| --- | --- | --- | --- | --- | --- |

> The granular data provided in RTS 27 and RTS 28 reports, when properly analyzed, can provide a powerful tool for optimizing venue selection and improving overall execution quality.

## What Is the Role of Technology in Best Execution?

Technology is a critical enabler of best execution under MiFID II. It provides the tools and infrastructure necessary to access liquidity, route orders intelligently, and monitor execution quality in a complex and fragmented market. The technological architecture for best execution should be designed to be flexible, scalable, and resilient. Key components of this architecture include:

- **Connectivity** ▴ The architecture must provide reliable and low-latency connectivity to a wide range of execution venues, including regulated markets, MTFs, OTFs, and SIs. This is typically achieved through the use of the Financial Information eXchange (FIX) protocol.

- **Order and Execution Management Systems (OEMS)** ▴ The OEMS is the central hub of the trading workflow. It should provide a comprehensive suite of tools for order management, execution, and risk management. A modern OEMS will also have integrated TCA and smart order routing capabilities.

- **Data and Analytics** ▴ The architecture must include a robust data and analytics platform for collecting, storing, and analyzing large volumes of market and execution data. This platform should be capable of supporting both real-time monitoring and historical analysis of execution quality.
