## Concept

The introduction of a Request for Quote (RFQ) aggregator into a trading workflow fundamentally alters the calculus of demonstrating best execution under the Markets in Financial Instruments Directive II (MiFID II). An RFQ aggregator systemizes the process of soliciting quotes from multiple [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), creating a centralized point of control and a detailed audit trail. This structured approach to price discovery directly addresses the core tenets of MiFID II, which mandate that firms 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 on a consistent basis. The aggregator transforms the ad-hoc nature of bilateral negotiations into a quantifiable, repeatable, and defensible process, thereby providing a robust framework for compliance.

## The Intersection of Technology and Regulation

At its core, the challenge of MiFID II compliance for off-book [liquidity sourcing](https://prime.greeks.live/area/liquidity-sourcing/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) lies in the ability to evidence the decision-making process. An [RFQ aggregator](https://prime.greeks.live/area/rfq-aggregator/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) provides a technological solution to this regulatory problem. By channeling all quote requests and responses through a single platform, the aggregator creates a comprehensive and time-stamped record of each transaction.

This data can then be used to demonstrate that a firm has surveyed a representative sample of the available market and has selected the best available quote based on the prescribed execution factors. The aggregator, in effect, becomes a key component of the firm’s [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) monitoring and reporting infrastructure.

## From Manual Processes to Automated Workflows

The transition from manual, voice-based RFQ processes to an aggregated, electronic workflow represents a significant evolution in [institutional trading](https://prime.greeks.live/area/institutional-trading/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This shift is driven by the need for greater efficiency, transparency, and control. An RFQ aggregator automates many of the manual tasks associated with traditional RFQ trading, such as contacting multiple dealers, tracking quotes, and recording trade details.

This automation reduces the risk of human error and frees up traders to focus on more strategic aspects of their roles. The result is a more streamlined and auditable trading process that is better aligned with the requirements of [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Strategy

The strategic implementation of an RFQ aggregator within a MiFID II compliance framework requires a nuanced understanding of the regulation’s requirements and the aggregator’s capabilities. The primary objective is to leverage the aggregator’s features to create a systematic and evidence-based approach to best execution. This involves configuring the aggregator to align with 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), defining clear criteria for venue and counterparty selection, and establishing a robust process for monitoring and reviewing [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). A well-defined strategy will ensure that the aggregator is not just a technology tool, but an integral part of the firm’s compliance and risk management framework.

> An effective RFQ aggregator strategy transforms compliance from a reactive, box-ticking exercise into a proactive, data-driven process that enhances execution quality and strengthens client relationships.

## Crafting a Defensible Execution Policy

A firm’s order [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is the cornerstone of its MiFID II compliance framework. When incorporating an RFQ aggregator, the policy must be updated to reflect the new workflow and the specific criteria that will be used to assess execution quality. This includes defining the relative importance of the various execution factors, such as price, speed, and likelihood of execution, for different types of financial instruments and client categories. The policy should also specify the process for selecting and onboarding liquidity providers to the aggregator, ensuring that they meet the firm’s due diligence requirements.

## Comparative Analysis of RFQ Aggregator Models

There are several different models of RFQ aggregators available, each with its own strengths and weaknesses. Some aggregators are provided by single dealers, while others are offered by independent technology vendors. The choice of aggregator will depend on a variety of factors, including the firm’s trading needs, its existing technology infrastructure, and its budget. A thorough due diligence process should be conducted to evaluate the different options and select the aggregator that best meets the firm’s requirements.

### Comparison of RFQ Aggregator Models

| Model | Advantages | Disadvantages |
| --- | --- | --- |
| Single-Dealer Platform | Deep liquidity from a single source Potentially lower direct costs Seamless integration with other services from the dealer | Limited competition Potential for information leakage Conflicts of interest |
| Multi-Dealer Platform | Increased competition and price transparency Access to a wider range of liquidity providers Reduced information leakage | Higher direct costs More complex integration Potential for fragmented liquidity |

## Execution

The execution of a MiFID II-compliant RFQ workflow using an aggregator requires a meticulous approach to data management, [performance monitoring](https://prime.greeks.live/area/performance-monitoring/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and reporting. The aggregator’s data feeds must be integrated with the firm’s other systems, such as its order management system (OMS) and [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) tools. This will enable the firm to capture a complete and accurate record of each transaction and to conduct a thorough analysis of its execution quality. The firm must also establish a regular process for reviewing its execution data and for making adjustments to its order execution policy and its use of the aggregator as needed.

## Data-Driven Performance Monitoring

The data generated by an RFQ aggregator is a valuable resource for monitoring and improving execution quality. This data can be used to track a variety of metrics, such as the number of quotes received per RFQ, the average spread between the best and second-best quotes, and the time taken to execute a trade. By analyzing this data, firms can identify trends and patterns in their execution quality and take steps to address any areas of concern. For example, if a firm finds that it is consistently receiving a low number of quotes for a particular type of instrument, it may need to add more liquidity providers to its aggregator for that instrument.

> The granular data provided by an RFQ aggregator empowers firms to move beyond a qualitative assessment of best execution to a quantitative and evidence-based approach.

## Reporting and Auditing

MiFID II requires firms to be able to demonstrate to [their clients](https://prime.greeks.live/question/how-do-anonymous-platforms-quantify-and-prove-their-effectiveness-in-mitigating-front-running-to-clients/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and to regulators that they have taken all sufficient steps to obtain the best possible result for their clients. The data generated by an RFQ aggregator can be used to create a variety of reports that can be used to meet this requirement. These reports can show, for example, the number of quotes received for each trade, the prices of those quotes, and the reason why a particular quote was selected. This information can be used to create a detailed [audit trail](https://prime.greeks.live/area/audit-trail/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that can be used to defend the firm’s execution decisions in the event of a regulatory inquiry.

### Key Metrics for RFQ Aggregator Performance Monitoring

| Metric | Description | Importance for MiFID II |
| --- | --- | --- |
| Number of Quotes per RFQ | The number of liquidity providers that respond to a request for a quote. | Demonstrates that the firm has surveyed a representative sample of the market. |
| Spread Between Best and Second-Best Quote | The difference in price between the best quote and the next-best quote. | Provides a measure of the competitiveness of the quotes received. |
| Time to Execute | The time taken from the initiation of the RFQ to the execution of the trade. | Demonstrates the speed and efficiency of the firm’s execution process. |
| Fill Rate | The percentage of RFQs that result in a trade. | Provides a measure of the likelihood of execution. |

The effective use of an RFQ aggregator can significantly enhance a firm’s ability to meet its best execution obligations under MiFID II. By providing a structured and auditable workflow for sourcing liquidity, an aggregator can help firms to demonstrate that they have taken all sufficient steps to obtain the best possible result for their clients. However, the successful implementation of an aggregator requires a strategic approach that encompasses not just the technology itself, but also the firm’s [order execution](https://prime.greeks.live/area/order-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) policy, its data management processes, and its performance monitoring and reporting framework.
