## Concept

The mandate for [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) under the Markets in Financial Instruments Directive II ([MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) presents a formidable set of technological challenges, particularly within the over-the-counter (OTC) derivatives market. The core of the issue resides in the fundamental structure of OTC products. These instruments are frequently bespoke, bilaterally negotiated, and lack the centralized price feeds characteristic of exchange-traded securities.

Consequently, demonstrating that a firm has taken “all [sufficient steps](https://prime.greeks.live/area/sufficient-steps/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” to achieve the optimal outcome for a client transcends a simple compliance exercise. It becomes a deep engineering problem centered on data aggregation, modeling, and the construction of a verifiable audit trail in an environment defined by informational asymmetry.

For an institution operating in this space, the directive effectively compels the creation of an internal, evidence-based framework to justify every execution decision. The technological lift required to meet this standard is substantial. It involves architecting systems capable of capturing, normalizing, and analyzing a wide array of disparate data points, many of which are unstructured.

This includes everything from voice-recorded quotes and instant message chats to data from various trading venues like Multilateral Trading Facilities (MTFs) and Organised Trading Facilities (OTFs). The objective is to construct a composite view of potential liquidity and pricing at the moment of execution, a task that is complicated by the inherent latency and fragmentation of the market.

## The Data Problem a New Foundation

The primary technological hurdle is the establishment of a robust data foundation. In the absence of a consolidated tape, firms must build their own. This involves integrating a heterogeneous mix of data sources, including direct dealer quotes, platform-based liquidity pools, and internal pricing models. The system must be capable of time-stamping all relevant events with a high degree of precision to reconstruct the state of the market at any given point.

This data serves as the raw material for all subsequent analysis and reporting, making its integrity paramount. The challenge lies in the variability of data formats and the need for sophisticated normalization logic to create a consistent and usable dataset. Without a solid data foundation, any attempt at systematic best execution analysis is built on sand.

## From Reasonable Steps to Sufficient Steps

MiFID II’s shift in language from “all reasonable steps” to “all sufficient steps” represents a significant elevation of the evidentiary burden. This change necessitates a move from a process-oriented approach to an outcome-oriented one. Technologically, this translates into a requirement for systems that can not only execute trades but also provide a quantitative justification for why a particular execution pathway was chosen.

This involves developing pre-trade analytics that can model the expected costs and risks of different execution strategies and post-trade analytics that can compare the actual execution against a range of benchmarks. The system must be able to produce detailed reports, such as the [RTS 27](https://prime.greeks.live/area/rts-27/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and RTS 28 filings, which provide regulators with a transparent view of the firm’s [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

> The core challenge of MiFID II for OTC derivatives is transforming fragmented, often qualitative pricing information into a structured, auditable, and quantitative evidence base for every trade.

The scope of financial instruments covered by MiFID II further compounds the technological complexity. The inclusion of a wider range of commodity derivatives and other non-standard instruments means that firms must develop flexible systems capable of handling a diverse set of product characteristics. Each instrument class may have its own unique market structure, liquidity profile, and pricing conventions, requiring tailored analytical models and data handling procedures.

This demands a modular and extensible system architecture that can adapt to the specific nuances of different OTC markets. The ultimate goal is to create a unified framework that can consistently apply the principles of best execution across the firm’s entire derivatives trading operation, regardless of the underlying product.

## Strategy

Addressing the technological demands of MiFID II’s best execution requirements for [OTC derivatives](https://prime.greeks.live/area/otc-derivatives/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) necessitates a cohesive strategy that integrates data management, analytical modeling, and execution workflow. The central strategic objective is to construct a system that provides a defensible and evidence-based rationale for every trading decision. This moves the firm from a reactive, compliance-driven posture to a proactive stance where execution quality becomes a measurable and optimizable component of the trading process. A successful strategy is predicated on three pillars ▴ unifying disparate data sources into a single analytical plane, developing a sophisticated pre- and post-trade analysis capability, and implementing a transparent and systematic [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

The initial phase of this strategy involves a comprehensive data architecture overhaul. Firms must move beyond siloed data repositories and create a centralized data fabric that can ingest and harmonize information from all relevant sources. This includes structured data from electronic trading venues and Approved Publication Arrangements (APAs), as well as unstructured data from voice and chat communications.

The strategic imperative is to create a “single source of truth” for market information, which can then be used to power the firm’s analytical and execution systems. This requires investment in [data capture](https://prime.greeks.live/area/data-capture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) technologies, normalization engines, and high-performance databases capable of handling time-series data at scale.

## A Framework for Execution Policy

A critical element of the strategy is the formalization of a detailed and transparent execution policy. This policy must articulate, for each class of OTC derivative, the factors that the firm will consider when selecting an execution venue or counterparty. These factors typically include price, costs, speed, likelihood of execution, and any other relevant considerations.

The technological strategy must then be aligned with this policy, ensuring that the firm’s systems are configured to capture the necessary data and perform the required analysis to support the stated policy. This creates a direct link between the firm’s regulatory obligations and its day-to-day trading operations.

The table below outlines a comparison of different strategic approaches to sourcing liquidity and achieving best execution for OTC derivatives under MiFID II.

| Execution Strategy | Description | Technological Requirements | Key Advantages | Primary Challenges |
| --- | --- | --- | --- | --- |
| Bilateral RFQ | Traditional Request-for-Quote sent to a limited number of dealers. | Integration with dealer APIs or proprietary portals. Manual data capture from chat/voice for post-trade analysis. | Access to specific dealer liquidity; potential for price improvement through competition. | Lack of pre-trade transparency; difficult to evidence a comprehensive market check; high potential for information leakage. |
| Multi-Dealer Platform (MTF/OTF) | Utilizing regulated electronic venues to solicit quotes from multiple participants simultaneously. | Direct connectivity to multiple MTF/OTF venues via FIX or proprietary APIs. Order and execution management system (OEMS) capable of aggregating responses. | Increased pre-trade transparency; automated audit trail; satisfies “sufficient steps” more easily. | Venue fees; potential for smaller trade sizes; not all dealers may participate on all platforms. |
| Systematic Internaliser (SI) | Executing against the firm’s own capital when certain quantitative thresholds are met. | Internal risk management and pricing engines; robust pre-trade quote publication infrastructure; post-trade reporting to an APA. | Control over execution; potential for reduced transaction costs; ability to handle large or sensitive orders. | Significant infrastructure investment; stringent regulatory obligations; potential for perceived conflicts of interest. |
| Hybrid Model | A combined approach using different strategies based on order size, instrument liquidity, and market conditions. | Sophisticated smart order routing (SOR) logic; real-time market data analysis to inform routing decisions; integrated TCA across all channels. | Flexibility to optimize execution for each specific order; balances access to liquidity with cost and transparency. | High degree of complexity in system design and maintenance; requires a mature governance framework. |

## Pre and Post Trade Analytics

The development of a robust [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) framework is another cornerstone of the strategic response. For OTC derivatives, TCA is significantly more complex than for listed equities due to the absence of a continuous public price feed. The strategy must therefore focus on creating meaningful benchmarks against which to measure execution quality. This might involve using the arrival price (the modeled price at the time the order is received), the average price of quotes received, or more sophisticated risk-adjusted benchmarks.

The technology must be able to capture all relevant data points and perform these calculations in a systematic and repeatable manner. The output of the TCA process then feeds back into the pre-trade analysis, creating a continuous improvement loop.

> A firm’s ability to prove best execution is directly proportional to the quality and comprehensiveness of its underlying data architecture and analytical capabilities.

Ultimately, the strategy must be dynamic and adaptable. The OTC market structure is constantly evolving, with new trading venues and technologies emerging. The firm’s systems and processes must be designed to accommodate this evolution.

This requires a commitment to ongoing investment in technology and a culture of continuous review and refinement of the execution policy. The following list outlines the core components of a comprehensive strategic plan:

- **Data Governance** ▴ Establish clear ownership and quality standards for all data related to the execution process. This includes developing a firm-wide data dictionary and implementing controls to ensure data accuracy and completeness.

- **System Integration** ▴ Create a seamless flow of information between the firm’s order [management system](https://prime.greeks.live/question/what-is-the-relationship-between-an-order-management-system-and-an-execution-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (OMS), [execution management system](https://prime.greeks.live/area/execution-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (EMS), and data analytics platforms. This eliminates manual processes and reduces the risk of errors.

- **Analytical Modeling** ▴ Develop and validate a suite of analytical models for pre-trade price estimation, execution [cost analysis](https://prime.greeks.live/area/cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and post-trade TCA. These models should be regularly back-tested and refined based on new data.

- **Reporting Automation** ▴ Automate the generation of all required regulatory reports, including RTS 27 and [RTS 28](https://prime.greeks.live/area/rts-28/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This reduces the operational burden and minimizes the risk of compliance failures.

- **Governance and Oversight** ▴ Implement a formal governance structure to oversee the firm’s best execution arrangements. This should include regular reviews of the execution policy, TCA results, and the performance of execution venues.

## Execution

The execution of a MiFID II-compliant best execution framework for OTC derivatives is a multi-faceted engineering endeavor. It requires the integration of advanced technology, quantitative analysis, and rigorous operational processes. The primary goal is to build a system that can systematically capture, analyze, and act upon market information to produce and evidence the best possible outcome for clients.

This system must be robust, scalable, and auditable, providing a complete and defensible record of every execution decision. The operational reality is that achieving this requires a granular focus on the entire trade lifecycle, from pre-trade analysis to [post-trade reporting](https://prime.greeks.live/area/post-trade-reporting/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

![Sleek teal and dark surfaces precisely join, highlighting a circular mechanism.

## The Data Capture and Normalization Engine

The foundational layer of the execution framework is the data capture and normalization engine. This system is responsible for ingesting data from a multitude of sources and transforming it into a structured, time-series format suitable for analysis. The technical challenge is immense, given the variety of data types and communication protocols involved.

A critical component is the ability to capture and digitize unstructured communications. For voice-based negotiations, this requires the implementation of natural language processing (NLP) technology to transcribe conversations and extract key data points such as instrument identifiers, quote levels, and trade sizes. For chat-based interactions, the system must be able to parse messages from various platforms (e.g.

Bloomberg, Symphony) and map them to the corresponding trade inquiries. All captured data must be time-stamped with a high degree of precision, ideally synchronized to a common clock source, to allow for accurate reconstruction of market conditions.

## Pre-Trade Price Discovery and Analytics

With a robust data foundation in place, the focus shifts to pre-trade analytics. The objective here is to provide the trader with a clear, evidence-based view of the available liquidity and pricing before an order is placed. For many OTC derivatives, a real-time, executable price is not readily available.

Therefore, the system must construct a “fair value” or “expected price” benchmark based on a variety of inputs. This process typically involves the following steps:

- **Data Aggregation** ▴ The system aggregates all available pricing information for the target instrument and any relevant proxy instruments. This includes indicative quotes from dealers, prices from inter-dealer broker screens, and data from MTFs and OTFs.

- **Model-Based Pricing** ▴ For more complex or illiquid instruments, the system will use internal pricing models to generate an expected price. These models are typically based on factors such as underlying asset prices, volatility surfaces, and interest rate curves.

- **Quote Solicitation** ▴ When the trader initiates a Request-for-Quote (RFQ), the system records all solicited counterparties and the specific terms of the request. This forms the initial part of the audit trail for the execution.

- **Response Analysis** ▴ As responses are received, the system captures the quoted prices and any associated conditions. It then compares these quotes against the pre-trade benchmark to identify potential outliers and assess the competitiveness of the pricing.

Radiating lines symbolize high-fidelity execution via smart order routing across dark pools](https://options.greeks.live/wp-content/uploads/2025/07/institutional-digital-asset-derivatives-rfq-high-fidelity-execution-architecture.jpg)

## Post-Trade Transaction Cost Analysis and Reporting

After a trade is executed, the system must perform a comprehensive [Transaction Cost](https://prime.greeks.live/area/transaction-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Analysis (TCA) to assess the quality of the execution and generate the necessary regulatory reports. This is where the evidentiary component of MiFID II comes into sharp focus. The TCA process must be systematic and applied consistently across all trades within a given instrument class.

The table below provides a granular view of the data fields required for a post-trade TCA report for a hypothetical EUR Interest Rate Swap, illustrating the level of detail necessary for robust analysis and reporting.

| Data Field | Description | Source System | Importance for TCA |
| --- | --- | --- | --- |
| Trade ID | Unique internal identifier for the trade. | Order Management System (OMS) | Primary key for linking all related data. |
| LEI of Counterparty | Legal Entity Identifier of the executing counterparty. | Counterparty Database | Essential for regulatory reporting (RTS 28) and counterparty analysis. |
| Timestamp (Order Receipt) | Precise time the client order was received. | OMS (synchronized clock) | Defines the arrival price benchmark. |
| Timestamp (Execution) | Precise time the trade was executed. | Execution Management System (EMS) | Measures execution latency and slippage from arrival. |
| Instrument ISIN/Identifier | Unique identifier for the derivative contract. | Reference Data System | Ensures accurate product identification and classification. |
| Notional Amount | The principal amount of the swap. | OMS/EMS | Critical for calculating costs and market impact. |
| Executed Price/Rate | The final fixed rate agreed for the swap. | EMS | The primary data point for price-based TCA. |
| Pre-Trade Benchmark | The system-generated expected price at the time of order receipt. | Analytics Engine | The main reference point for measuring price improvement or slippage. |
| Quotes Received | A structured list of all quotes received, including counterparty and price. | Data Capture Engine | Provides evidence of a competitive process and market check. |
| Explicit Costs | Any commissions or fees associated with the trade. | Fee Management System | A key component of the total cost calculation. |

> The ultimate measure of a successful MiFID II execution system is its ability to produce a complete, time-sequenced, and data-rich narrative for every trade, leaving no ambiguity as to why a particular execution decision was made.

The output of this TCA process serves multiple purposes. It provides the compliance function with the necessary data to produce RTS 27 (for SIs) and RTS 28 reports, demonstrating the firm’s execution quality to regulators and clients. It also provides the trading desk with valuable feedback on the performance of different execution strategies, venues, and counterparties. This data-driven feedback loop is essential for the continuous improvement of the firm’s execution process, transforming a regulatory requirement into a source of competitive advantage.

## From Mandate to Mechanism

The intricate web of rules surrounding MiFID II’s best execution requirements for OTC derivatives forces a fundamental re-evaluation of a firm’s operational architecture. The regulations compel a shift from reliance on convention and relationships to a dependency on verifiable data and systematic process. This transition, while technologically demanding, offers a profound opportunity.

It prompts a critical examination of how information flows through an organization, how decisions are made, and how value is ultimately defined and measured. The process of building a compliant system is, in essence, the process of building a more intelligent trading apparatus.

The true endpoint of this journey is the creation of a system that not only satisfies regulatory scrutiny but also generates a persistent strategic advantage. When the entire execution workflow is captured, digitized, and analyzed, it becomes a source of proprietary market intelligence. The insights gleaned from this data can inform everything from trader behavior and counterparty selection to the development of more sophisticated pricing models and risk management techniques. The technological framework built to meet a mandate becomes the engine of institutional learning and adaptation, a mechanism for achieving a superior level of operational control and capital efficiency in a complex and competitive market.
