## Concept

A firm’s analysis of its [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a foundational component of its operational integrity. Within this rigorous evaluation, [price improvement](https://prime.greeks.live/area/price-improvement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) emerges as a critical, quantifiable metric. It represents the practice of executing a client’s order at a price more favorable than the prevailing National Best Bid and Offer (NBBO). For a buy order, this means securing a price below the national best offer; for a sell order, it involves achieving a price above the national best bid.

The monetary value derived from this advantageous execution, however small on a per-share basis, aggregates into substantial capital preservation for the client over time. The existence of such opportunities is a direct consequence of modern market structure, where a significant volume of liquidity is not publicly displayed on lit exchanges.

This [non-displayed liquidity](https://prime.greeks.live/area/non-displayed-liquidity/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), often residing in alternative trading systems (ATS) or with market makers, creates a reservoir of potential value. A firm’s execution architecture, specifically its smart order routing ([SOR](https://prime.greeks.live/area/sor/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) systems and connectivity to diverse liquidity pools, determines its ability to access these pockets of improved pricing. The analysis of price improvement, therefore, becomes a direct audit of the firm’s technological capabilities and its strategic routing decisions.

It moves the conversation from a theoretical obligation of “[best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” to a data-driven assessment of performance. A sophisticated analysis does not simply count the instances of price improvement; it quantifies the total value delivered and benchmarks this performance against the available liquidity profile of the market at the moment of execution.

> Price improvement is the measurable outcome of an execution system’s ability to source liquidity at prices superior to the publicly quoted market.

The core of the analysis hinges on a simple calculation ▴ the difference between the actual [execution price](https://prime.greeks.live/area/execution-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and the [NBBO](https://prime.greeks.live/area/nbbo/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) at the time the order was routed. For instance, if a client places a market order to purchase 1,000 shares of a security with an NBBO offer price of $25.30, and the firm’s system executes the trade at $25.29, the per-share price improvement is $0.01. This yields a total saving of $10.00 for the client on that single transaction. This calculation, repeated across thousands or millions of trades, forms a powerful dataset.

This data allows a firm’s [Best Execution Committee](https://prime.greeks.live/area/best-execution-committee/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to dissect performance, identify patterns, and hold its execution venues and internal systems accountable. It is a feedback mechanism for the continuous optimization of the firm’s trading infrastructure.

## Sourcing and Routing for Optimal Pricing

A firm’s strategy for systematically generating price improvement is rooted in its order routing logic and its access to a diverse ecosystem of liquidity. The primary mechanism for this is a [Smart Order Router](https://prime.greeks.live/area/smart-order-router/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (SOR), an automated system designed to find the optimal execution venue for an order based on a set of pre-defined rules. A basic SOR might simply route to the exchange displaying the best price within the NBBO. An advanced, institutional-grade SOR operates on a more complex level.

It maintains a persistent connection to numerous execution venues simultaneously, including lit exchanges, multiple alternative trading systems (ATS), and private [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Its strategy is to intelligently query these venues to uncover non-displayed, better-priced liquidity before committing the order.

The strategic decision-making process involves a continuous evaluation of which venues historically provide the most significant price improvement for specific types of securities under particular market conditions. For example, the system may learn that a certain dark pool consistently offers midpoint execution for large-cap technology stocks, while a specific wholesaler provides superior pricing for less liquid small-cap names. This routing strategy is dynamic, adapting to real-time [market data](https://prime.greeks.live/area/market-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and historical performance analytics. The goal is to create a competitive environment for the firm’s order flow, where multiple venues are compelled to offer better prices to win the execution.

## The Framework of Transaction Cost Analysis

[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)) provides the quantitative framework for measuring the effectiveness of a firm’s price improvement strategy. TCA moves beyond simple execution price and delves into the implicit costs of trading, such as market impact and timing risk. Within a TCA report, price improvement is a key component of the “slippage” calculation. Slippage is measured against a variety of benchmarks, with the most common being the arrival price ▴ the midpoint of the NBBO at the moment the firm receives the order.

> Effective Transaction Cost Analysis transforms price improvement from an abstract benefit into a concrete performance indicator for execution routing.

A positive slippage outcome, where the execution price is better than the arrival price benchmark, is a direct result of price improvement. A comprehensive TCA report will break down price improvement by venue, by order size, and by security type, providing the granular detail needed for strategic adjustments. This allows a firm to objectively compare the performance of its different liquidity providers and routing pathways. It answers critical questions ▴ Which venues are adding the most value?

Are we sacrificing speed for price, and is the trade-off worth it? Is the price improvement we are receiving substantial or merely a fraction of the available bid-ask spread?

The table below illustrates a simplified comparison of execution venues within a TCA framework, highlighting how price improvement is isolated and measured.

| Execution Venue | Order Type | Total Shares | Arrival Price (NBBO Midpoint) | Average Execution Price | Price Improvement per Share | Total Price Improvement ($) |
| --- | --- | --- | --- | --- | --- | --- |
| Wholesaler A | Market Buy | 10,000 | $50.155 | $50.151 | $0.004 | $40.00 |
| Dark Pool X | Market Buy | 10,000 | $50.155 | $50.155 | $0.000 | $0.00 |
| Lit Exchange Y | Market Buy | 10,000 | $50.155 | $50.160 (Offer Price) | -$0.005 | -$50.00 |
| Internalizer B | Market Buy | 10,000 | $50.155 | $50.152 | $0.003 | $30.00 |

## The Operational Playbook for Analysis

A firm’s Best Execution Committee is tasked with the systematic review of execution quality. The analysis of price improvement is a central pillar of this function. The process is cyclical, involving data capture, analysis, reporting, and strategic adjustment. It is an ongoing operational discipline, not a one-time event.

- **Data Aggregation** ▴ The first step is the high-fidelity capture of order and execution data. For every single client order, the system must log the precise timestamp of receipt, the NBBO at that moment, the full lifecycle of the order as it is routed to one or more venues, and the final execution price and timestamp for each fill. This data is typically captured by the firm’s [Execution Management System](https://prime.greeks.live/area/execution-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (EMS) and aggregated into a centralized data warehouse.

- **Benchmark Calculation** ▴ For each execution, the system calculates the potential for price improvement. This is the difference between the execution price and the relevant NBBO price (the bid for a sell, the offer for a buy) at the time of routing. This value is calculated on a per-share basis and then aggregated across the entire order.

- **Venue Performance Attribution** ▴ The aggregated price improvement data is then segmented by execution venue. The analysis seeks to determine the average price improvement per share, the frequency of price improvement, and the total dollar value of improvement contributed by each venue. This allows the committee to rank its liquidity providers based on tangible performance.

- **Outlier Investigation** ▴ The analysis must also identify and investigate outliers. This includes trades with significant negative price improvement (slippage) as well as trades with zero price improvement. The committee must ask why certain orders failed to capture any available spread. Was it due to market conditions, a routing logic failure, or a specific venue’s lack of liquidity?

- **Reporting and Strategic Review** ▴ The findings are compiled into a comprehensive quarterly report for the Best Execution Committee. This report will feature visualizations and tables that clearly illustrate performance trends. Based on this report, the committee will make strategic decisions, which could include re-ranking venues in the SOR, renegotiating terms with liquidity providers, or investing in new connectivity or trading technology.

## Quantitative Modeling and Data Analysis

The quantitative analysis of price improvement goes beyond simple averages. A sophisticated approach uses statistical models to understand the drivers of performance. The Effective/Quoted Spread Ratio is a key metric in this analysis.

It compares the spread the client actually paid (the effective spread) against the spread that was publicly quoted at the time of the order (the quoted spread). A ratio below 100% indicates that, on average, the firm’s executions occurred inside the NBBO, demonstrating price improvement.

The table below presents a hypothetical dataset for a Best Execution Committee review. It analyzes performance across different order sizes for a specific security, providing a granular view of where the execution system is adding value.

| Order Size Bucket | Total Orders | % Orders with PI | Average PI per Share (cents) | Total PI Value ($) | Effective/Quoted Spread Ratio |
| --- | --- | --- | --- | --- | --- |
| 100-499 shares | 15,250 | 92.5% | 0.21¢ | $18,540 | 78% |
| 500-1,999 shares | 8,140 | 88.1% | 0.18¢ | $21,350 | 81% |
| 2,000-9,999 shares | 3,450 | 75.4% | 0.12¢ | $15,670 | 89% |
| 10,000+ shares | 620 | 61.2% | 0.08¢ | $9,880 | 94% |

This data reveals a critical pattern ▴ while the firm is consistently generating price improvement, the effectiveness diminishes as order size increases. This is an expected outcome, as larger orders have a greater market impact and are more challenging to fill without crossing the spread. The analysis allows the firm to quantify this effect and explore strategies to improve large-order execution quality, perhaps by using more sophisticated algorithmic order types that break large orders into smaller pieces. It also provides a clear, evidence-based justification for the firm’s execution strategy and demonstrates its commitment to fulfilling its best execution obligations.

## System Integration and Technological Architecture

The effective analysis of price improvement is contingent upon a tightly integrated technological stack. The process begins and ends with the firm’s [Order Management System](https://prime.greeks.live/area/order-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (OMS) and Execution [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) (EMS).

- **Order Management System ([OMS](https://prime.greeks.live/area/oms/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite))** ▴ The OMS is the system of record for all client orders. It must capture every detail of the order intake, including the client ID, security, size, order type, and the precise time of receipt. This initial timestamp is the anchor for all subsequent analysis, particularly for establishing the arrival price benchmark.

- **Execution Management System (EMS)** ▴ The EMS contains the logic for how an order is worked in the market. This includes the smart order router (SOR) and any algorithmic trading strategies. The EMS must log every routing decision, every message sent to a venue (typically via the FIX protocol), and every execution report received. This detailed audit trail is essential for attributing price improvement to specific venues and strategies.

- **Market Data Infrastructure** ▴ To accurately calculate price improvement, the firm needs a robust market data infrastructure capable of capturing and storing a historical record of the NBBO for every traded security, tick by tick. When an order is executed, the system must be able to query this database to retrieve the exact NBBO that existed at the moment the order was routed, providing the benchmark against which the execution price is compared.

## A System of Continuous Refinement

The rigorous analysis of price improvement is ultimately a commitment to building a self-correcting execution system. The data gathered and the reports generated are not historical artifacts; they are active inputs into a dynamic feedback loop. Each data point, whether it confirms a strategy’s success or reveals a weakness, provides an opportunity to refine the firm’s technological architecture and routing logic. This process transforms the obligation of best execution from a compliance exercise into a source of competitive and operational advantage.

Viewing price improvement through this lens elevates the discussion. It becomes a measure of a firm’s intelligence layer ▴ its ability to translate vast amounts of market data into superior outcomes for its clients. The ultimate goal is an execution framework so finely tuned that it consistently uncovers value that is invisible to less sophisticated market participants. This pursuit of operational excellence is the core principle of a truly client-focused firm.
