## Concept

A firm’s obligation to deliver [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is fundamentally a claim that must be substantiated by data. The technological infrastructure is the apparatus responsible for producing the evidence to support that claim. Its design dictates the quality, completeness, and verifiability of the narrative of every trade.

A robust infrastructure transforms the [best execution review](https://prime.greeks.live/area/best-execution-review/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) from a reactive, compliance-driven exercise into a proactive, data-centric capability that underpins the entire trading operation. It is the system that ensures every decision point in an order’s lifecycle is captured, timestamped, and preserved with immutable integrity.

The core purpose of this infrastructure is to create a single, coherent, and auditable record of the entire trading process. This record encompasses not just the firm’s own actions but also the state of the market at the precise moment of those actions. Without this contextual [market data](https://prime.greeks.live/area/market-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), a firm’s [execution data](https://prime.greeks.live/area/execution-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) exists in a vacuum, making a rigorous assessment of its quality impossible. The technological challenge, therefore, is one of integration and synchronization ▴ fusing the internal order flow with external market states into a unified dataset that can withstand the scrutiny of regulators, clients, and internal oversight committees.

> A best execution review’s integrity is a direct reflection of the integrity of the data collection systems that support it.

This perspective shifts the focus from merely storing trade records to architecting a system for evidence collection. Every component, from the [Order Management System](https://prime.greeks.live/area/order-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (OMS) to the [data warehouse](https://prime.greeks.live/area/data-warehouse/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), becomes a link in a chain of custody for data. The quality of the final review is therefore determined from the outset by the capabilities of the underlying technology to capture data with sufficient granularity and accuracy.

A failure in the infrastructure ▴ such as unsynchronized clocks or incomplete data logging ▴ is a failure in the firm’s ability to prove its adherence to its fiduciary duties. Consequently, investment in this infrastructure is an investment in the firm’s operational integrity and credibility.

## Strategy

A strategic approach to designing a technological infrastructure for [best execution data](https://prime.greeks.live/area/best-execution-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) collection is centered on achieving three primary objectives ▴ completeness, context, and accessibility. Completeness ensures that every relevant data point across the order lifecycle is captured. Context involves synchronizing that trade data with concurrent market data to enable meaningful analysis.

Accessibility ensures that the collected data can be efficiently queried and analyzed by compliance, trading, and management functions. The overarching strategy is to build a data ecosystem that serves as the firm’s definitive record of its trading activities.

## The Principle of Total Lifecycle Capture

A best [execution review](https://prime.greeks.live/question/what-are-the-key-differences-between-a-regular-execution-quality-review-and-an-annual-best-execution-report/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) requires a comprehensive view of an order’s journey. The [data collection](https://prime.greeks.live/area/data-collection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) strategy must therefore ensure that every material event and decision point is logged. This begins the moment a client order is received and continues through to its final allocation.

A fragmented approach, where different systems log data in disparate formats and locations, creates data silos that are difficult and costly to reconcile. A centralized data strategy is paramount.

The key stages and data points to capture include:

- **Order Receipt and Handling** ▴ This includes the initial timestamp of order receipt, the order’s terms (instrument, size, side, order type), and any special handling instructions. This data is typically generated by the Order Management System (OMS).

- **Pre-Trade Analysis** ▴ For larger orders, this may involve logging the results of pre-trade [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA), which models expected market impact and costs. This provides a baseline against which to measure [execution quality](https://prime.greeks.live/question/how-should-a-firms-best-execution-committee-use-rfq-data-to-oversee-and-improve-execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

- **Order Routing and Execution** ▴ This is the most data-intensive stage. The infrastructure must log which venues an order was routed to, the timestamps of those routes, any modifications or cancellations, and the details of each partial and final execution. This includes the execution venue, price, size, and any associated fees or rebates.

- **Post-Trade Allocation** ▴ For block orders that are allocated to multiple client accounts, the system must record the allocation methodology and the specific allocations made.

## Achieving Context through Data Synchronization

An [execution price](https://prime.greeks.live/question/what-are-the-primary-differences-between-a-first-price-and-a-second-price-auction-in-an-rfq-context/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is meaningless without the context of the prevailing market conditions. A key strategic challenge is to capture and synchronize market data with the firm’s internal order and trade data. This allows for the calculation of crucial best execution metrics.

> The ability to benchmark internal execution data against a synchronized record of external market activity is the cornerstone of a credible best execution analysis.

The infrastructure must be capable of ingesting and storing high-frequency data streams from all relevant trading venues. This includes:

- **Top-of-Book Quotes** ▴ The best bid and offer (BBO) from all relevant exchanges and trading venues.

- **Depth-of-Book Data** ▴ For more sophisticated analysis, the system may need to capture data on orders resting at multiple price levels in the order book.

- **Last Sale Data** ▴ A record of all trades occurring on relevant venues.

The critical technological component for achieving this synchronization is high-precision, centrally managed timestamping. All systems ▴ OMS, [Execution Management System](https://prime.greeks.live/area/execution-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (EMS), market data feeds, and logging servers ▴ must be synchronized to a common clock source, typically using the Network Time Protocol (NTP) or Precision Time Protocol (PTP). The required level of precision (e.g. millisecond, microsecond) will depend on the firm’s trading strategy and the asset classes it trades.

## Data Governance and Accessibility

Once collected, the vast amount of data must be managed, stored, and made accessible for analysis. A sound [data governance](https://prime.greeks.live/area/data-governance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) framework is essential to ensure data quality, consistency, and security. The strategic choice of data storage technology is also critical. While traditional relational databases can be used, many firms are moving towards more scalable and flexible data lake or data warehouse solutions capable of handling the large volumes of structured and unstructured data involved.

The table below outlines a strategic framework for the data infrastructure:

| Component | Strategic Objective | Key Technologies | Primary Data Outputs |
| --- | --- | --- | --- |
| Data Capture Layer | Ensure complete and accurate logging of all order and trade events. | OMS/EMS with comprehensive logging, FIX Protocol message capture, Market Data Feeds. | Raw order messages, execution reports, time-stamped market data ticks. |
| Data Synchronization Layer | Provide a unified time reference across all data sources. | NTP/PTP servers, timestamping libraries integrated into applications. | Synchronized log files with common time reference. |
| Data Storage & Governance Layer | Centralize data storage and ensure data integrity and accessibility. | Data warehouse or data lake, data quality tools, access control systems. | Normalized and enriched trade and market data, auditable data lineage. |
| Analytics & Reporting Layer | Enable the calculation of best execution metrics and the generation of regulatory reports. | Transaction Cost Analysis (TCA) engines, business intelligence (BI) tools, custom reporting applications. | RTS 27/28 reports, internal execution quality reviews, slippage analysis. |

By adopting a strategic approach that prioritizes completeness, context, and accessibility, a firm can build a technological infrastructure that not only satisfies its regulatory obligations but also provides valuable insights to improve trading performance and reduce operational risk.

## Execution

The execution of a data collection strategy for best execution reviews requires a detailed focus on the technological and procedural components that form the firm’s trading and data architecture. This involves configuring specific systems, leveraging standardized protocols, and implementing robust data management processes to create an auditable and analysis-ready dataset.

## The Role of the FIX Protocol

The Financial Information eXchange (FIX) protocol is the lingua franca of the electronic trading world. A significant portion of the data required for a best execution review is contained within the FIX messages that flow between the firm, its clients, its vendors, and the execution venues. The firm’s infrastructure must be configured to capture and archive all relevant FIX messages for the entire order lifecycle.

Certain FIX tags are particularly critical for best execution analysis. The table below details some of the most important tags and their relevance:

| FIX Tag | Field Name | Description | Relevance to Best Execution Review |
| --- | --- | --- | --- |
| 11 | ClOrdID | The unique identifier for the order, assigned by the firm. | Serves as the primary key for tracking an order throughout its lifecycle. |
| 35 | MsgType | Defines the type of FIX message (e.g. New Order, Execution Report). | Allows for the reconstruction of the sequence of events for an order. |
| 38 | OrderQty | The size of the order. | A key component of the original order terms. |
| 44 | Price | The price of the order (for limit orders). | The target price against which execution quality can be measured. |
| 54 | Side | The side of the order (e.g. Buy, Sell). | A fundamental characteristic of the order. |
| 60 | TransactTime | The time the message was created and transmitted. | A critical timestamp for measuring latency and sequencing events. |
| 30 | LastMkt | The market of execution for the last fill. | Identifies the venue of execution, essential for venue analysis. |
| 31 | LastPx | The price of the last fill. | The actual execution price, a core component of TCA. |
| 32 | LastQty | The quantity of the last fill. | The size of the execution, used to track order completion. |

The firm’s systems, particularly the EMS and OMS, must not only log these messages but also ensure that the TransactTime (Tag 60) is populated with a high-precision, synchronized timestamp. This timestamp is the evidentiary anchor for when an action was taken.

## System Architecture for Data Aggregation

The execution of the data collection strategy hinges on an architecture designed for aggregation and centralization. A typical high-level architecture would include the following components:

- **Message Capture Agents** ▴ These are lightweight processes that run on or alongside the trading systems (OMS, EMS, FIX engines). Their sole purpose is to capture all inbound and outbound FIX messages and other relevant log data, apply a high-precision timestamp, and forward the data to a central message bus.

- **Central Message Bus** ▴ Technologies like Apache Kafka or RabbitMQ can be used to create a resilient, high-throughput pipeline for all trading-related data. This decouples the data producers (trading systems) from the data consumers (storage and analytics systems).

- **Data Normalization and Enrichment Service** ▴ A service that consumes data from the message bus, parses the different log formats (e.g. FIX, proprietary logs), and transforms the data into a standardized schema. This service would also enrich the trade data by joining it with the synchronized market data for the time of the execution. For example, when an execution report is processed, this service would look up the National Best Bid and Offer (NBBO) at the TransactTime and append it to the trade record.

- **Central Data Repository** ▴ This is the final destination for the normalized and enriched data. As discussed, this is typically a data warehouse or data lake optimized for handling large time-series datasets. The repository should be designed to allow for efficient querying of data by order ID, time range, client, or instrument.

> A well-architected data pipeline automates the collection, normalization, and storage of best execution data, minimizing manual intervention and reducing the risk of data errors.

## The Best Execution Review Process

With the data collected and stored in a central repository, the firm can execute a systematic and data-driven best execution review. The process typically involves:

- **Regular Reporting** ▴ Automated processes query the data repository to generate regular reports for the Best Execution Committee. These reports would summarize key metrics such as:

<li>**Price Improvement/Deterioration** ▴ The difference between the execution price and the BBO at the time of order receipt or routing.

- **Effective Spread** ▴ A measure of the cost of liquidity, calculated based on the execution price relative to the midpoint of the BBO.

- **Slippage** ▴ The difference between the expected price of a trade (e.g. the arrival price) and the final execution price.

- **Venue Analysis** ▴ A breakdown of execution quality by trading venue, as required by regulations like [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s [RTS 28](https://prime.greeks.live/area/rts-28/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

</li>
- **Exception-Based Monitoring** ▴ The analytics layer can be configured to automatically flag trades that fall outside of pre-defined tolerance levels for the above metrics. This allows the compliance team to focus its attention on potential outliers that may require further investigation.

- **Deep-Dive Analysis** ▴ For flagged trades or upon request, compliance officers and traders can use analytics tools to perform a deep dive into the full lifecycle of an order. They can reconstruct the sequence of events, view the market conditions at each decision point, and understand why a particular routing decision was made.

This systematic, data-centric process provides the firm with a defensible and auditable record of its efforts to achieve best execution. It moves the firm beyond simple compliance reporting to a state of continuous monitoring and improvement of its execution quality.

## From Mandate to Mechanism

The mandate for best execution is a constant. The mechanism by which a firm demonstrates its fulfillment of that mandate, however, is a direct function of its technological vision. The systems described are not merely data plumbing; they constitute the central nervous system of the trading operation. The quality of the data it carries and the insights it enables are a reflection of the firm’s commitment to transparency and performance.

A firm that views this infrastructure as a compliance cost will build a system to match. A firm that sees it as a source of competitive and operational advantage will architect a system that delivers it.

## The Unblinking Witness

Ultimately, the infrastructure serves as an unblinking, impartial witness to every trading decision. It records the state of the world and the actions taken in response, without bias or narrative. The challenge for the firm is to build a system that is worthy of that trust. Does the data architecture provide a complete and faithful record?

Can it withstand the most rigorous cross-examination from clients, regulators, and internal auditors? The answers to these questions reveal the true quality of a firm’s commitment to its clients. The data does not lie; the only question is whether the infrastructure is capable of telling the whole truth.
