## Concept

Evaluating the performance of a Request for Quote (RFQ) system presents a complex challenge. A superficial analysis of outcomes, such as which liquidity provider (LP) offered the best price, often fails to account for the intricate network of factors that influence each quotation. The core issue is [selection bias](https://prime.greeks.live/area/selection-bias/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). LPs do not receive the same RFQs under the same conditions.

One provider might be queried more frequently for large, illiquid orders during volatile periods, while another is predominantly engaged for smaller, standard trades in a calm market. A simple comparison of win rates or [price improvement](https://prime.greeks.live/area/price-improvement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) metrics between these two LPs would be fundamentally flawed, attributing performance differences to the provider’s skill or pricing engine when they may simply reflect the different nature of the [order flow](https://prime.greeks.live/area/order-flow/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) they were shown.

This is where the statistical methodology of [Propensity Score Matching](https://prime.greeks.live/area/propensity-score-matching/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (PSM) provides a robust framework for creating a fair comparison. PSM is a technique born from the need to estimate causal effects in observational studies, where, like in financial markets, randomized controlled trials are impossible. Its primary function is to correct for the baseline differences between groups, allowing for a more accurate assessment of a specific “treatment.” In the context of [RFQ performance](https://prime.greeks.live/area/rfq-performance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the “treatment” could be the decision to send an RFQ to a particular LP or a specific group of LPs.

The goal of PSM is to construct a fair comparison by asking ▴ if two different LPs had been given the exact same profile of RFQs, how would their performance have differed? It achieves this by modeling the probability, or “propensity,” of an RFQ being sent to a particular LP based on its observable characteristics.

> Propensity Score Matching allows for a more precise and fair comparison of RFQ performance by statistically controlling for the underlying differences in the order flow each liquidity provider receives.

By matching RFQs sent to different LPs that have [similar propensity scores](https://prime.greeks.live/question/why-do-dependency-based-anomaly-scores-provide-a-stronger-signal-for-financial-fraud-than-proximity-based-scores/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), an analyst can create a synthetic dataset where the distribution of observable characteristics is balanced across the groups being compared. This process effectively mimics a randomized experiment, isolating the true performance of the LP from the confounding effects of the order flow it tends to receive. This allows a trading desk to move beyond simple leaderboards and toward a nuanced understanding of which providers excel under specific market conditions and for particular types of trades. The result is a more accurate and actionable intelligence layer for optimizing the RFQ routing process.

## Strategy

## Moving beyond Naive Metrics

The conventional approach to evaluating RFQ performance often relies on a set of straightforward, yet potentially misleading, metrics. These include win rates, average price improvement over a benchmark, and response times. While these indicators provide a surface-level view, they are susceptible to significant distortions caused by underlying variables. An LP might have a high win rate simply because it is shown easier-to-price, less risky RFQs.

Conversely, a provider specializing in difficult, large-in-scale block trades might show a lower win rate and wider spreads, yet deliver immense value in a specific, crucial niche. Relying on these naive metrics alone can lead to suboptimal routing decisions, such as penalizing a valuable specialist LP or rewarding a generalist provider whose performance is inflated by the simplicity of its flow.

The strategic imperative for employing [Propensity Score](https://prime.greeks.live/question/how-does-a-dealers-business-model-affect-their-propensity-for-information-leakage-in-rfq-protocols/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Matching is to dismantle these confounding effects and establish a true, like-for-like comparison. The core of the strategy involves identifying and controlling for the covariates that influence both the routing decision (the “treatment”) and the performance outcome. These covariates are the DNA of an RFQ and the market environment in which it exists.

## Key Covariates in RFQ Performance Analysis

- **Order-Specific Variables** ▴ These define the intrinsic characteristics of the request itself.

<li>**Notional Value** ▴ The size of the order is a primary determinant of its risk and the pricing offered.

- **Instrument Liquidity** ▴ The underlying liquidity of the asset being traded heavily influences spread and execution feasibility.

- **Order Type** ▴ A simple single-leg order is fundamentally different from a complex multi-leg spread.

</li>
- **Market Condition Variables** ▴ These capture the state of the market at the moment of the request.

<li>**Volatility** ▴ Realized and implied volatility at the time of the RFQ directly impacts risk pricing.

- **Time of Day** ▴ Market depth and liquidity can vary significantly throughout the trading session.

- **Spread of the Underlying** ▴ The bid-ask spread of the instrument on the central limit order book provides a baseline for the expected RFQ spread.

## The PSM Process a Strategic Framework

The implementation of PSM follows a structured, multi-step process designed to systematically eliminate bias. The first step is to define the treatment and [control groups](https://prime.greeks.live/question/what-role-do-crisis-management-groups-play-in-the-resolution-of-a-globally-systemic-central-counterparty/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). For instance, a trading desk might want to compare the performance of “LP Group A” (the [treatment group](https://prime.greeks.live/area/treatment-group/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) against all other LPs (the control group).

The next, and most critical, step is to develop a statistical model, typically a [logistic regression](https://prime.greeks.live/area/logistic-regression/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), to estimate the propensity score for each RFQ. This score represents the predicted probability of that specific RFQ being sent to LP Group A, given its unique set of covariates.

> By creating matched pairs of RFQs with similar propensity scores, one sent to the treatment group and one to the control, the analysis can proceed as if the RFQs were assigned randomly.

Once [propensity scores](https://prime.greeks.live/question/why-do-dependency-based-anomaly-scores-provide-a-stronger-signal-for-financial-fraud-than-proximity-based-scores/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) are calculated for all RFQs, a matching algorithm is applied. Common techniques include nearest-neighbor matching, which pairs a treated RFQ with the control RFQ that has the closest propensity score, and caliper matching, which imposes a maximum distance between scores for a valid match. The outcome of this matching process is a new, smaller dataset where the distribution of covariates is balanced between the treatment and control groups. It is on this balanced dataset that performance metrics are recalculated.

Any remaining difference in performance between the two groups can then be attributed with much greater confidence to the “treatment” itself ▴ the skill, technology, or risk appetite of the LPs ▴ rather than to the confounding influence of the order flow they received. This provides a robust foundation for data-driven decisions on LP selection and RFQ routing logic.

## The Operational Playbook

Implementing Propensity [Score Matching](https://prime.greeks.live/question/how-does-a-counterparty-performance-score-differ-from-a-traditional-credit-score/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to evaluate RFQ performance is a rigorous, data-intensive process that transforms raw trading data into strategic intelligence. This playbook outlines the key operational steps required to move from data collection to actionable insights.

- **Data Aggregation and Preparation** ▴ The foundation of any PSM analysis is a comprehensive dataset. This requires capturing detailed information for every RFQ sent, including not just the winning quote, but all quotes received. Crucially, this must be merged with a snapshot of the market state at the time of each request. This involves integrating data from multiple sources ▴ the internal [trading system](https://prime.greeks.live/area/trading-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for RFQ details, a market data provider for volatility and spread data, and potentially a data warehouse where historical trade data is stored.

- **Defining the Analytical Scope** ▴ The next step is to clearly define the question being investigated. Is the goal to compare a single LP against the field? Or to compare two specific LPs against each other? Or perhaps to evaluate a new routing strategy? This definition will determine the “treatment” and “control” groups for the analysis. For example, to evaluate “LP-X”, the treatment group would be all RFQs sent to LP-X, and the control group would be all RFQs sent to any other LP.

- **Propensity Score Estimation** ▴ With the data prepared and the groups defined, a logistic regression model is built to predict the probability of an RFQ being assigned to the treatment group. The dependent variable is a binary indicator (1 if in the treatment group, 0 otherwise), and the independent variables are the covariates identified in the strategy phase (notional value, volatility, etc.). The output of this model is the propensity score for each RFQ.

- **Matching and Balance Assessment** ▴ A matching algorithm is then used to create pairs of treated and control RFQs with [similar propensity](https://prime.greeks.live/question/how-does-a-dealers-business-model-affect-their-propensity-for-information-leakage-in-rfq-protocols/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) scores. After matching, it is critical to assess the balance of the covariates between the new, matched groups. This is typically done by comparing the means of each covariate in the treated and control groups and ensuring there are no statistically significant differences. If imbalances persist, the propensity score model may need to be refined by adding more relevant covariates or interaction terms.

- **[Treatment Effect](https://prime.greeks.live/area/treatment-effect/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Estimation** ▴ Once balance is achieved, the performance metrics of interest (e.g. price improvement, effective spread) are calculated for both the treated and control groups within the matched sample. The difference in these metrics provides the Average Treatment Effect on the Treated (ATT), which is the estimate of the true performance difference, free from the selection bias.

## Quantitative Modeling and Data Analysis

To illustrate the process, consider a simplified example. A trading desk wants to compare the performance of a specialist provider, “LP-Alpha,” against the rest of the market. They collect data on 10,000 RFQs, noting the covariates for each.

First, they build a logistic regression model to predict the likelihood of an RFQ being sent to LP-Alpha. The model might look like this:

_P(Sent to LP-Alpha) = β₀ + β₁(Notional) + β₂(Volatility) + β₃(Spread) + ε_

The table below shows a small sample of the raw data, including the calculated propensity score for each RFQ.

### Table 1 ▴ Pre-Match RFQ Data with Propensity Scores

| RFQ ID | Sent to LP-Alpha (Treatment) | Notional (in M) | Volatility (%) | Propensity Score | Price Improvement (bps) |
| --- | --- | --- | --- | --- | --- |
| 1 | 1 | 50 | 2.5 | 0.85 | 3.2 |
| 2 | 0 | 5 | 1.2 | 0.15 | 1.5 |
| 3 | 0 | 45 | 2.4 | 0.83 | 2.8 |
| 4 | 1 | 8 | 1.3 | 0.18 | 1.9 |
| 5 | 0 | 10 | 1.4 | 0.22 | 2.1 |

After running a nearest-neighbor matching algorithm on the propensity scores, a new, balanced dataset is created. Notice how RFQ 1 (treated) is matched with RFQ 3 (control) as they have very similar propensity scores, indicating they are comparable requests. Similarly, RFQ 4 is matched with a hypothetical control RFQ that had a similar propensity score.

### Table 2 ▴ Post-Match Data Showing Balanced Pairs

| Matched Pair | Group | Notional (in M) | Volatility (%) | Propensity Score | Price Improvement (bps) |
| --- | --- | --- | --- | --- | --- |
| A | Treatment (LP-Alpha) | 50 | 2.5 | 0.85 | 3.2 |
| B | Treatment (LP-Alpha) | 8 | 1.3 | 0.18 | 1.9 |

By averaging the price improvement for the treatment and control groups in this new matched sample, the desk can calculate the unbiased performance of LP-Alpha. If the average price improvement for LP-Alpha in the matched set is 3.0 bps and for the control group is 2.9 bps, the ATT is +0.1 bps, suggesting a modest but positive performance edge for LP-Alpha on a like-for-like basis.

## System Integration and Technological Architecture

The successful execution of a PSM framework for RFQ analysis is contingent upon a robust technological architecture. This is not a one-off spreadsheet analysis but an integrated component of a modern trading system. The architecture must support the entire lifecycle of the analysis, from data capture to the operationalization of insights.

- **Data Capture and Storage** ▴ A high-fidelity data capture mechanism is paramount. The trading system’s database must be designed to store not only the details of each RFQ (instrument, size, direction) and its responses (timestamps, prices), but also to link each request to a rich set of market data at the precise moment of its creation. This typically involves a time-series database capable of storing granular market data (like top-of-book quotes and volatility surfaces) and a relational database for the transactional RFQ data.

- **Analytical Environment** ▴ The core PSM analysis is best performed in a dedicated analytical environment, such as a Python or R server. These environments provide access to the necessary statistical libraries (e.g. scikit-learn and statsmodels in Python, or MatchIt in R) for logistic regression and matching. The environment needs read-access to the production data stores, often through a replicated database or a data warehouse to avoid impacting the performance of the live trading system.

- **Feedback Loop to Execution Systems** ▴ The ultimate goal of this analysis is to improve future trading decisions. The insights generated from the PSM analysis must be fed back into the Order and Execution Management System (OMS/EMS). This can take several forms. It could be a periodic, manual update to the LP routing table based on a quarterly performance review. In a more advanced setup, the performance scores could be used to dynamically adjust the probability of sending an RFQ to a particular LP based on the real-time characteristics of the order, creating a “smart” RFQ routing system that learns and adapts based on rigorous, bias-corrected performance data. This creates a powerful, data-driven feedback loop that continuously optimizes execution quality.

## From Measurement to Mechanism

Adopting a framework like Propensity Score Matching fundamentally shifts the objective of performance analysis. The goal is no longer simply to measure outcomes and rank participants, but to understand the underlying mechanisms that drive those outcomes. It forces a deeper inquiry into the very nature of the order flow and the strategic decisions that shape it. By controlling for the ‘what’ ▴ the characteristics of the RFQs ▴ the system can begin to illuminate the ‘why’ and the ‘how’ of provider performance.

This analytical rigor provides more than just a better scorecard. It builds a more sophisticated mental model of the liquidity landscape. It reveals the niches where specialist providers create unique value, the conditions under which generalists are most competitive, and the subtle interplay between market volatility and execution quality.

This understanding, embedded within the operational logic of a trading system, is a significant component of a durable competitive advantage. The ultimate value lies in transforming the function of performance review from a historical report into a forward-looking instrument of execution strategy.
