## Concept

An institutional [Request for Quote](https://prime.greeks.live/area/request-for-quote/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) system functions as a high-fidelity data capture mechanism, creating an immutable, time-stamped ledger of every interaction throughout the [price discovery](https://prime.greeks.live/area/price-discovery/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and execution lifecycle. This intrinsic record-keeping is the foundational element for demonstrating adherence to the MiFID II best execution mandate. The directive requires firms to take all sufficient steps to obtain the best possible result for their clients, a standard that necessitates a verifiable and auditable trail of the decision-making process. The RFQ protocol, by its very design, generates this trail as a natural byproduct of its operation.

The process begins when a trading desk initiates a query for a specific financial instrument. The system logs the precise moment of the request, the anonymized identifiers of the liquidity providers selected for the auction, and the full parameters of the desired trade, including instrument identifiers and size. As each counterparty responds, the system captures their offered price and size, alongside a timestamp accurate to the microsecond. This collection of competing quotes forms a permanent, objective snapshot of the available liquidity and pricing at a specific moment in time.

The final execution record, including the winning quote, transaction costs, and settlement details, completes the log. This complete data set provides the evidentiary basis for all subsequent analysis and reporting, transforming the abstract requirement of “[best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” into a series of concrete, measurable, and defensible data points.

> A bilateral price discovery system inherently generates the granular, time-stamped audit trail required to substantiate MiFID II best execution compliance.

This systemic documentation moves the process of compliance away from subjective post-trade narratives and into the realm of quantitative validation. The focus becomes an analysis of the data records to prove that the [execution policy](https://prime.greeks.live/question/how-should-an-order-execution-policy-balance-the-need-for-information-control-against-the-duty-of-best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) was followed. The quality of execution is no longer a matter of opinion but a conclusion drawn from a robust dataset. The [RFQ system](https://prime.greeks.live/area/rfq-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s log is the source of truth, enabling firms to reconstruct any trade, justify the choice of counterparty, and demonstrate that the outcome was the result of a structured, competitive, and fair process, fully in line with the principles set forth by the regulation.

## Strategy

A strategic approach to [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) compliance leverages the RFQ system as a central pillar of the firm’s execution quality framework. This involves designing an [order execution policy](https://prime.greeks.live/area/order-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that explicitly links the regulation’s required factors to the specific data points generated by the quote solicitation protocol. The objective is to create a closed-loop system where the policy dictates the parameters of execution, the RFQ system records the performance against those parameters, and the resulting data is used to refine the policy and demonstrate adherence.

## Defining the Execution Factors

The core of the strategy lies in translating the qualitative factors of MiFID II into quantitative metrics that the [RFQ](https://prime.greeks.live/area/rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) system can track. The regulation mandates that firms consider several factors to ensure the best possible result for their clients. While price and cost are significant, they are part of a broader set of considerations. The relative importance of these factors is determined by the firm based on client character, order characteristics, and the nature of the financial instrument.

A firm’s execution policy must articulate how it prioritizes these factors for different scenarios. For instance, for a large, illiquid order, the likelihood and speed of execution might be given greater weight than achieving the absolute best price, due to the risk of market impact. Conversely, for a small order in a liquid instrument, price and explicit costs would be the dominant factors. The RFQ system must be configured to capture the necessary data to evaluate performance against all these dimensions.

## Mapping Execution Factors to RFQ Data

The following table illustrates how the primary MiFID II best execution factors are mapped to concrete data points captured within a modern RFQ system. This mapping is the critical link between the firm’s stated policy and its ability to prove compliance.

| MiFID II Execution Factor | Primary RFQ System Data Points | Strategic Purpose |
| --- | --- | --- |
| Price | All quotes received from liquidity providers (LP), winning quote price, benchmark price at time of request (e.g. composite feed), time-to-respond for each LP. | To create a defensible record showing the executed price was the best available from the solicited group of LPs at that specific time. |
| Costs | Explicit commission fields, fee structures per LP, clearing and settlement charges, stamp duties or other taxes. | To provide a full accounting of the total consideration for the transaction, ensuring transparency and allowing for net price comparisons. |
| Speed of Execution | Timestamp of RFQ initiation, timestamp of each LP response, timestamp of final execution message. | To measure the efficiency of the execution process and the responsiveness of LPs, a critical factor in fast-moving markets. |
| Likelihood of Execution | Historical fill ratios for each LP, number of quotes received vs. requested, cancellation and rejection rates per LP. | To build a quantitative basis for selecting counterparties that have a high probability of completing trades, minimizing execution risk. |
| Size and Nature of the Order | Order size, instrument type (e.g. bond, derivative), liquidity profile of the instrument (e.g. ISIN, LEI). | To contextualize the execution outcome, justifying why certain factors were prioritized for a specific trade. |
| Likelihood of Settlement | Counterparty settlement success rates, data from post-trade settlement systems integrated with the RFQ platform. | To assess the operational reliability of counterparties, ensuring that the full lifecycle of the trade is secure. |

## Counterparty and Venue Selection

The data captured by the RFQ system is instrumental in the ongoing assessment of liquidity providers and execution venues. A systematic review of performance metrics allows the firm to maintain a dynamic and optimized list of counterparties. This is a core requirement of MiFID II.

- **Performance Monitoring** ▴ Firms must establish a formal process for reviewing the execution quality delivered by each counterparty. This involves analyzing the [RFQ data](https://prime.greeks.live/area/rfq-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to rank LPs based on criteria such as average price improvement, response times, and fill ratios.

- **Qualitative Assessment** ▴ The quantitative data is supplemented with qualitative judgments. This can include the counterparty’s financial stability, their communication during market stress, and their support for complex trades.

- **Demonstrable Process** ▴ The selection and review process must be documented. The RFQ system’s data provides the evidence to support decisions to add or remove counterparties from the approved list, creating a clear audit trail for regulators.

> The strategic use of RFQ data transforms the compliance function from a historical reporting exercise into a dynamic, forward-looking process for optimizing execution quality.

Ultimately, the strategy is to embed the MiFID II framework into the firm’s operational DNA. The RFQ system serves as the central nervous system, capturing every relevant data point and enabling the firm to not only meet its regulatory obligations but also to continuously enhance its execution capabilities for the benefit of its clients. This data-driven approach ensures that the firm’s best execution policy is a living document, constantly validated and refined by real-world performance metrics.

## Execution

The execution of a MiFID II [compliance framework](https://prime.greeks.live/area/compliance-framework/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) hinges on the system’s ability to produce a granular, structured, and complete record of all trading activities. The RFQ system’s logs are the raw material from which all proof of adherence is constructed. This section details the specific data structures and procedural workflows required to translate raw RFQ data into demonstrable compliance with best execution principles.

## The Foundational Data Log

At its core, the RFQ system must generate a detailed event log for every quote request. This log is more than a simple trade blotter; it is a comprehensive, chronological record of every state change and data point from the initiation of the request to its final settlement. The table below outlines the critical fields that a MiFID II-compliant RFQ system must capture. This level of detail provides the irrefutable evidence needed for any regulatory inquiry or internal audit.

## From Raw Data to Demonstrable Compliance

With this foundational data log, the firm can implement procedures to aggregate and analyze the information, producing reports that directly address the MiFID II requirements. This process typically involves a [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ([TCA](https://prime.greeks.live/area/tca/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) function, which can be internal or provided by a third-party specialist.

## Procedural Workflow for Best Execution Review

A compliance officer or best execution committee would follow a structured process to verify adherence to the firm’s policy. This workflow is a practical application of the data captured by the RFQ system.

- **Data Aggregation** ▴ On a periodic basis (e.g. quarterly), all RFQ log data for the period is extracted from the system and loaded into an analytical database.

- **Metric Calculation** ▴ A series of pre-defined queries and algorithms are run against the dataset to calculate key performance indicators (KPIs) for each execution factor. This includes calculating average response times, fill ratios per counterparty, and price performance against benchmarks.

- **Outlier Identification** ▴ The analysis will flag any trades that fall outside of expected parameters. For example, an execution at a price significantly worse than other quotes received, or a trade with an unusually long execution time.

- **Qualitative Investigation** ▴ For each identified outlier, the compliance officer investigates the circumstances. This involves reviewing trader notes, market conditions at the time of the trade (using the precise timestamps), and the rationale for the execution decision.

- **Counterparty Performance Review** ▴ The aggregated data is used to produce a scorecard for each [liquidity provider](https://prime.greeks.live/area/liquidity-provider/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This scorecard ranks LPs across multiple dimensions, providing a quantitative basis for the ongoing review of the counterparty list.

- **Reporting and Documentation** ▴ A formal report is generated summarizing the findings of the review. This report includes the aggregated metrics, details of any outlier investigations, and any recommendations for changes to the execution policy or counterparty list. This document serves as the primary evidence of ongoing monitoring.

> The transformation of discrete, time-stamped log entries into aggregated performance metrics is the mechanism by which a firm proves its adherence to its execution policy.

The following table provides a simplified example of what a summary report might contain. This report synthesizes the millions of individual data points from the RFQ log into a high-level overview that is meaningful for management and regulators.

## Table ▴ Sample Best Execution Quarterly Report Summary

| Metric | Asset Class ▴ Corporate Bonds | Asset Class ▴ Interest Rate Swaps | Commentary |
| --- | --- | --- | --- |
| Total RFQs Sent | 15,230 | 8,450 | Volume analysis provides context for statistical significance. |
| Overall Fill Ratio | 96.5% | 98.2% | Measures the overall likelihood of execution across all counterparties. |
| Average Price Improvement vs. Mid | +1.2 bps | +0.5 bps | Demonstrates price quality relative to a standard market benchmark. |
| Average Execution Speed (Request to Fill) | 2.1 seconds | 3.5 seconds | Tracks the efficiency of the execution process. |
| Top 3 Counterparties by Fill Ratio | LP-A (99%), LP-C (98%), LP-B (97%) | LP-D (99.5%), LP-A (99%), LP-F (98%) | Provides a quantitative basis for counterparty evaluation. |
| Percentage of Trades with Explicit Costs | 100% | 100% | Confirms that cost transparency is being maintained. |

This systematic, data-centric execution of the compliance process ensures that the firm’s adherence to MiFID II is not a matter of assertion, but of verifiable proof. The RFQ system, in this context, is the essential infrastructure that makes such a rigorous and defensible process possible.

## The System as the Standard

The assembled data, the structured reports, and the documented procedures all point to a single operational truth ▴ the integrity of the execution system defines the integrity of the compliance outcome. The adherence to MiFID II’s principles is not an overlay applied after the fact; it is a direct output of the system’s architecture. Viewing the RFQ platform as a data-generation engine first and a trading tool second reframes the entire challenge. It prompts a deeper inquiry into the operational framework itself.

Does the current system capture every necessary data point with sufficient granularity? Is the analytical layer capable of transforming raw logs into actionable intelligence for both compliance and trading performance? The answers to these questions reveal the true robustness of a firm’s commitment to the best execution standard. The regulation provides the questions; the system provides the answers.
