## Concept

The obligation of [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) within the Request for Quote (RFQ) market operates on a tiered system of duties, fundamentally calibrated to the presumed level of sophistication of the client. At its core, the distinction between retail and [professional clients](https://prime.greeks.live/area/professional-clients/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a recognition that not all market participants possess the same capacity to evaluate the quality of a price quote. For a retail client, the regulatory framework presupposes a greater reliance on the firm to protect their interests.

This initiates a more stringent set of responsibilities for the executing firm. Conversely, when dealing with a [professional client](https://prime.greeks.live/area/professional-client/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the framework allows for a greater degree of latitude, acknowledging their ability to conduct their own due diligence and to understand the complexities of market dynamics.

## The Presumption of Reliance

The core difference in [best execution obligations](https://prime.greeks.live/area/best-execution-obligations/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is rooted in the concept of “legitimate reliance.” For retail clients, reliance is the default assumption. The firm must act in the client’s best interest, and the burden of proof is on the firm to demonstrate that it has taken [all sufficient steps](https://prime.greeks.live/area/all-sufficient-steps/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to achieve the best possible result. This is a high bar, and it means that the firm must consider a range of factors beyond just the price, including costs, speed, and the likelihood of execution. For professional clients, the presumption of reliance is weaker.

While the best execution obligation still applies, there is a greater recognition that professional clients are more likely to be “shopping around” for quotes and are therefore less reliant on any single firm to protect their interests. This distinction is critical in the [RFQ](https://prime.greeks.live/area/rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) context, where quotes are often bespoke and not publicly disseminated.

## Defining the Best Possible Result

The definition of “best [possible result](https://prime.greeks.live/question/how-does-implied-volatility-skew-affect-the-range-of-possible-strike-prices-for-a-zero-cost-structure/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” also differs between the two client categories. For retail clients, the best possible result is defined primarily in terms of the [total consideration](https://prime.greeks.live/area/total-consideration/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which is the price of the financial instrument plus all associated costs. Other factors, such as speed and likelihood of execution, can only be prioritized if they are instrumental in delivering the best total consideration. This creates a clear, quantifiable metric for assessing best execution.

For professional clients, the definition of best possible result is more flexible. While price and costs are still important, the firm can give greater weight to other factors, such as the size of the order, the nature of the market, and the client’s specific instructions. This allows for a more nuanced approach to execution that can be tailored to the specific needs of the professional client.

## Strategy

The strategic implementation of best [execution obligations](https://prime.greeks.live/question/how-do-regulatory-frameworks-like-mifid-ii-impact-rfq-execution-and-best-execution-obligations/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in the RFQ market requires a nuanced approach that is tailored to the specific client category. For [retail clients](https://prime.greeks.live/area/retail-clients/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the strategy is one of paternalistic protection, where the firm acts as a fiduciary, guiding the client towards the best possible outcome. For professional clients, the strategy is one of partnership, where the firm provides the client with the tools and information they need to make their own informed decisions.

## Retail Client Strategy a Framework of Protection

For retail clients, the best [execution strategy](https://prime.greeks.live/guide/why-your-execution-strategy-is-as-important-as-your-trading-strategy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is built on a foundation of clear policies, transparent disclosure, and robust monitoring. The firm’s [order execution policy](https://prime.greeks.live/area/order-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) must be provided to the client in a clear and easily understandable format, and it must explicitly state how the firm will ensure best execution. The firm must also obtain the client’s prior consent to the execution policy. This creates a clear contractual framework that protects both the client and the firm.

The firm must also have in place a robust monitoring process to ensure that it is consistently delivering best execution. This includes regular reviews of its execution arrangements and a process for identifying and correcting any deficiencies.

> The best execution framework for retail clients prioritizes total consideration, encompassing both price and costs, as the primary measure of execution quality.

The following table outlines the key components of a [retail client](https://prime.greeks.live/area/retail-client/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) best execution strategy:

### Retail Client Best Execution Strategy

| Component | Description | Regulatory Basis |
| --- | --- | --- |
| Order Execution Policy | A clear and detailed policy outlining how the firm will execute client orders to achieve the best possible result. | MiFID II Article 27 |
| Client Consent | The firm must obtain the client’s prior consent to the order execution policy. | MiFID II Article 27 |
| Disclosure | The firm must provide clients with a summary of its order execution policy. | MiFID II Article 27 |
| Monitoring | The firm must regularly monitor the effectiveness of its execution arrangements and policy. | MiFID II Article 27 |

This visually represents the precision of institutional-grade digital asset derivatives RFQ execution](https://options.greeks.live/wp-content/uploads/2025/07/institutional-digital-asset-derivatives-rfq-protocol-execution-precision-1.jpg)

## Professional Client Strategy a Partnership Approach

For professional clients, the best execution strategy is more collaborative. The firm is still obligated to take all sufficient steps to obtain the best possible result, but there is a greater emphasis on the client’s own expertise and judgment. The firm’s role is to provide the client with the information and tools they need to assess the quality of the firm’s quotes and to make their own [execution decisions](https://prime.greeks.live/question/how-can-machine-learning-be-deployed-to-improve-execution-routing-decisions-over-time/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

This includes providing information on the firm’s pricing methodology, the venues it uses for execution, and any potential conflicts of interest. The firm must also be prepared to justify its execution decisions to the client and to provide them with data to support its claims.

The following list outlines the key considerations for a professional client best execution strategy:

- **Transparency** ▴ The firm should be transparent about its pricing and execution practices.

- **Information** ▴ The firm should provide the client with the information they need to make informed decisions.

- **Justification** ▴ The firm should be able to justify its execution decisions to the client.

- **Flexibility** ▴ The firm should be willing to accommodate the client’s specific instructions and preferences.

## Execution

The execution of RFQ orders in a manner that satisfies best execution obligations requires a sophisticated operational framework. The specific processes and controls will vary depending on the client category, but the overarching goal is to ensure that the firm is consistently acting in the best interests of its clients. 

![Abstract depiction of an advanced institutional trading system, featuring a prominent sensor for real-time price discovery and an intelligence layer.

## Executing for Retail Clients a Prescriptive Approach

For retail clients, the [execution process](https://prime.greeks.live/question/what-are-the-primary-legal-differences-between-a-tender-process-and-an-rfp-process-in-public-sector-procurement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is highly prescriptive. The firm must have in place a detailed order handling process that is designed to ensure that all orders are treated fairly and in accordance with the firm’s [best execution policy](https://prime.greeks.live/area/best-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This includes procedures for recording and time-stamping orders, for routing orders to the appropriate execution venue, and for monitoring the quality of execution.

The firm must also have in place a system for identifying and managing any potential conflicts of interest. This is particularly important in the RFQ market, where the firm may be acting as both principal and agent.

> For retail clients, the execution process is meticulously structured to ensure fairness and adherence to the best execution policy, with a strong emphasis on conflict-of-interest management.

The following table outlines the key steps in the retail client RFQ execution process:

### Retail Client RFQ Execution Process

| Step | Description | Key Controls |
| --- | --- | --- |
| Order Receipt | The firm receives an RFQ from a retail client. | Time-stamping of the request, verification of client identity and categorization. |
| Quoting | The firm generates a quote for the client. | The quote must be based on the best available market prices and must be fair and reasonable. |
| Execution | The client accepts the quote and the firm executes the trade. | The trade must be executed promptly and at the quoted price. |
| Confirmation | The firm provides the client with a confirmation of the trade. | The confirmation must include all relevant details of the trade, including the price, costs, and execution venue. |
| Monitoring | The firm monitors the quality of the execution. | The firm must have in place a process for identifying and correcting any deficiencies in its execution arrangements. |

## Executing for Professional Clients a Flexible Framework

For professional clients, the execution process is more flexible. The firm is still required to have in place a robust order handling process, but there is a greater degree of latitude in how it is implemented. The firm can take into account the client’s specific instructions and preferences, and it can use a wider range of [execution venues](https://prime.greeks.live/area/execution-venues/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

The firm must also be prepared to demonstrate to the client that it has taken all sufficient steps to obtain the best possible result. This may involve providing the client with detailed [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) reports and other data to support its execution decisions.

The following list outlines the key considerations for executing RFQ orders for professional clients:

- **Client Instructions** ▴ The firm must have a process for capturing and acting on client instructions. 

- **Venue Selection** ▴ The firm should have a process for selecting the most appropriate execution venue for each order.

- **TCA** ▴ The firm should be able to provide clients with detailed TCA reports to demonstrate the quality of its execution.

- **Conflicts of Interest** ▴ The firm must have a process for managing any potential conflicts of interest.

## Calibrating the Execution Framework

The delineation of best execution obligations between retail and professional clients is a foundational element of modern financial regulation. It acknowledges the diverse levels of sophistication among market participants and tailors the protective framework accordingly. For firms operating in the RFQ space, a deep understanding of these distinctions is paramount. It informs the design of their trading systems, the structure of their client-facing policies, and the very nature of their relationship with those they serve.

The regulatory requirements should not be viewed as a mere compliance exercise. Instead, they provide a blueprint for building a robust and resilient execution framework that can adapt to the evolving needs of a diverse clientele. By embracing the spirit of the regulations, firms can cultivate relationships built on trust and transparency, ultimately fostering a more efficient and equitable market for all.
