## Concept

[Post-trade reversion analysis](https://prime.greeks.live/question/how-does-post-trade-reversion-analysis-inform-future-counterparty-selection-for-block-trades/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) functions as a high-fidelity diagnostic instrument for the request-for-quote (RFQ) protocol. Its purpose is to quantify the economic cost of [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) by measuring price movements that systematically disadvantage a trader’s executed price. Within the architecture of institutional trading, the RFQ is designed as a contained, private mechanism for sourcing liquidity, a direct communication channel between a client and a select group of dealers. This structure is intended to minimize the market impact associated with large orders.

Information leakage represents a structural vulnerability in this protocol. The act of sending an RFQ, by its nature, discloses valuable, private information ▴ specifically, the asset, direction, and potential size of an impending trade ▴ to a concentrated group of market participants. Leakage occurs when a solicited dealer, or an entity they communicate with, uses this private information to trade ahead of the client’s order or otherwise position themselves to profit from the client’s activity.

This pre-positioning creates [adverse price movement](https://prime.greeks.live/question/how-can-quantitative-models-differentiate-between-coincidental-market-movement-and-actual-dealer-front-running/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for the client. The market price moves away from the client before the execution is complete, leading to a higher purchase price or a lower sale price.

> Post-trade reversion analysis provides a quantitative measure of this adverse price movement, serving as a direct indicator of execution quality and potential protocol breaches.

The core analytical principle involves examining the behavior of an asset’s price in the moments and minutes immediately following a trade’s execution. A systematic pattern of reversion reveals the quality of the [execution price](https://prime.greeks.live/area/execution-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). For a buy order, reversion is the tendency of the price to fall after the trade; for a sell order, it is the tendency for the price to rise. This price action suggests the execution occurred at a temporary, unfavorable price dislocation, often caused by the very trading activity of informed participants who acted on the leaked RFQ information.

This process is a form of forensic market analysis. It moves beyond simple [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) by seeking to identify the cause of poor execution. Standard TCA measures slippage against a benchmark, such as the volume-weighted average price (VWAP) or arrival price.

[Reversion analysis](https://prime.greeks.live/area/reversion-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) isolates the post-trade behavior to diagnose a specific pathology. A consistent pattern of high reversion linked to specific dealers or trading scenarios provides strong, data-driven evidence that the [RFQ protocol](https://prime.greeks.live/area/rfq-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) itself is being compromised, turning a tool for discreet execution into a source of costly information leakage.

## Strategy

A strategic framework for using [post-trade reversion](https://prime.greeks.live/area/post-trade-reversion/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) analysis to detect information leakage is built on comparative analytics and the systematic isolation of variables. The objective is to move from observing reversion to attributing it to specific causes, primarily the behavior of dealers within an RFQ panel. This requires a disciplined, scientific approach to structuring and analyzing trade data.

![Precision metallic component, possibly a lens, integral to an institutional grade Prime RFQ. Its layered structure signifies market microstructure and order book dynamics](https://options.greeks.live/wp-content/uploads/2025/08/high-fidelity-institutional-digital-asset-rfq-execution-engine.jpg)

## Foundational Reversion Measurement

The initial step involves establishing a baseline measurement for post-trade reversion. This is calculated for every significant trade executed via the RFQ process. The metric itself is straightforward ▴ it is the difference between the execution price and the market’s [midpoint price](https://prime.greeks.live/question/what-are-the-primary-risks-associated-with-execution-in-a-midpoint-dark-pool/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) at a series of defined time intervals after the trade. Common intervals include 1 minute, 5 minutes, and 15 minutes post-execution.

The formula for reversion (in basis points) for a buy trade is:

_Reversion (bps) = (Execution Price – [Post-Trade Midpoint Price](https://prime.greeks.live/question/what-are-the-primary-risks-associated-with-execution-in-a-midpoint-dark-pool/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) / Execution Price 10,000_

For a sell trade, the formula is:

_Reversion (bps) = (Post-Trade Midpoint Price – Execution Price) / Execution Price 10,000_

A positive reversion value is always unfavorable to the trader, indicating the price moved against the position after the trade was completed.

## Comparative Analysis the Key to Isolating Leakage

A single reversion metric is insufficient to diagnose information leakage. [Market volatility](https://prime.greeks.live/area/market-volatility/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), momentum, and the inherent characteristics of an asset all contribute to [price movement](https://prime.greeks.live/question/how-can-quantitative-models-differentiate-between-coincidental-market-movement-and-actual-dealer-front-running/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The strategic layer of the analysis introduces control groups and comparative frameworks to isolate the impact of dealer behavior.

> The strategy hinges on segmenting trade data to create controlled experiments that reveal patterns of behavior.

This is achieved by categorizing trades based on the panel of dealers who received the RFQ. The core analytical exercise is to compare reversion metrics for trades executed after sending an RFQ to different cohorts of dealers. For instance, an institution might analyze all trades where the RFQ was sent to Dealer Group A (Dealers 1, 2, 3) versus Dealer Group B (Dealers 4, 5, 6).

- 
**Dealer Paneling** ▴ Trades are grouped by the specific set of dealers solicited in the RFQ. This allows for direct comparison of performance when different dealers are privy to the trade information.

- 
**Winner-Loser Analysis** ▴ The analysis differentiates between the [winning dealer](https://prime.greeks.live/question/how-does-information-leakage-in-an-rfq-affect-hedging-costs-for-the-winning-dealer/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and the losing dealers in the RFQ auction. High reversion when a specific dealer wins the trade may indicate poor pricing. High reversion when a specific dealer loses the trade could suggest that the losing dealer is trading on the information, a classic sign of leakage.

- 
**Volatility Normalization** ▴ Reversion metrics are adjusted for the prevailing market volatility at the time of the trade. A high reversion figure during a period of extreme market-wide volatility is less indicative of leakage than the same figure in a quiet market. This normalization creates a “[Leakage Index](https://prime.greeks.live/question/how-does-the-volatility-skew-for-an-individual-stock-differ-from-that-of-a-broad-market-index/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” that represents the excess reversion unexplained by [general market conditions](https://prime.greeks.live/question/how-can-an-institution-measure-the-market-impact-of-a-large-block-trade-independently-from-general-market-volatility/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## What Is the Strategic Goal of This Analysis?

The ultimate goal is to build a dynamic, data-driven dealer management system. The output of the reversion analysis directly informs the composition of RFQ panels. Dealers who consistently exhibit high leakage signatures can be downgraded or removed from panels for sensitive trades.

Conversely, dealers who demonstrate low reversion and respect for the protocol’s integrity are elevated and receive more order flow. The table below outlines the strategic shift from a basic TCA approach to a sophisticated [leakage detection framework](https://prime.greeks.live/question/how-can-tick-size-reductions-affect-the-signal-to-noise-ratio-in-leakage-detection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

| Analytical Framework | Primary Metric | Core Question | Strategic Outcome |
| --- | --- | --- | --- |
| Standard Transaction Cost Analysis (TCA) | Slippage vs. Arrival Price | What was my cost of execution? | Benchmarking overall trading performance. |
| Basic Post-Trade Reversion Analysis | Post-Trade Price Reversion (in bps) | Did I get a good price at the moment of execution? | Identifying trades with significant adverse selection. |
| Strategic Leakage Detection Framework | Volatility-Normalized Reversion, Attributed to Dealer Panels | Why was the price poor, and who is responsible for the information leakage? | Dynamic, data-driven dealer routing and risk management to proactively minimize leakage. |

## Execution

Executing a robust post-trade reversion analysis program requires a synthesis of high-quality data, a rigorous quantitative framework, and a clear process for translating analytical findings into actionable trading protocols. This is the operational playbook for building a system to detect and mitigate information leakage.

## The Operational Playbook Data Infrastructure

The foundation of any credible analysis is the quality and granularity of the underlying data. The system must capture and synchronize multiple data streams with high-precision timestamps, ideally at the microsecond or nanosecond level.

- 
**RFQ Message Capture** ▴ Log every aspect of the RFQ lifecycle. This includes the timestamp of the RFQ submission, the list of dealers on the panel, the timestamps of each dealer’s response (or failure to respond), the quoted prices, and the timestamp of the final execution message. This data is often captured via [FIX protocol](https://prime.greeks.live/area/fix-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) logs.

- 
**Execution Data** ▴ Record the final trade details, including execution price, size, time, and the winning dealer. This must be linked directly to the parent RFQ message that initiated the trade.

- 
**Market Data Capture** ▴ Independently capture a high-frequency feed of the consolidated order book for the traded asset. This feed must include top-of-book quotes (bids and asks) and last-trade prices from all relevant lit markets. This data is essential for calculating the market’s true midpoint price at any given nanosecond.

- 
**Data Warehousing** ▴ All three data streams (RFQ, execution, market) must be stored in a time-series database that allows for efficient querying and joining of the datasets based on their timestamps.

## Quantitative Modeling and Data Analysis

With the data infrastructure in place, the next step is to apply the quantitative model. The analysis moves from raw reversion numbers to a normalized “Leakage Index” that controls for [market conditions](https://prime.greeks.live/question/how-do-exchanges-define-stressed-market-conditions-for-market-makers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and attributes cost to dealer behavior. The following table provides a simplified example of what the output of such an analysis would look like for a series of buy trades in the same security.

| Trade ID | Winning Dealer | Losing Dealers | Reversion (T+1min, bps) | Market Volatility Index | Expected Reversion (bps) | Leakage Index (bps) |
| --- | --- | --- | --- | --- | --- | --- |
| 101 | Dealer A | B, C | 1.5 | Low (0.8) | 0.5 | 1.0 |
| 102 | Dealer D | E, F | 0.7 | Low (0.8) | 0.5 | 0.2 |
| 103 | Dealer B | A, C | 4.2 | High (2.5) | 2.0 | 2.2 |
| 104 | Dealer A | D, E | 0.9 | Low (0.8) | 0.5 | 0.4 |
| 105 | Dealer C | A, B | 3.1 | High (2.5) | 2.0 | 1.1 |

The **[Expected Reversion](https://prime.greeks.live/question/what-are-the-primary-challenges-in-mapping-anomaly-scores-to-expected-financial-loss/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** is a modeled value based on historical data, predicting the reversion given the market volatility. The **Leakage Index** is calculated as ▴ _Raw Reversion – Expected Reversion_. This critical metric represents the portion of [adverse price](https://prime.greeks.live/question/how-can-tca-differentiate-between-price-improvement-and-adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) movement that cannot be explained by general market conditions. In the example above, Trade 103 has the highest raw reversion, but it occurred in a volatile market.

Trade 101, however, has a high Leakage Index despite lower raw reversion, suggesting a more significant issue. A pattern emerges where panels including Dealers B and C seem to correlate with higher leakage.

## How Should This Data Reshape Trading Strategy?

The analysis transitions from a report to a living component of the trading system. The Leakage Index becomes a key input for smart order routing logic and dealer scoring.

> The objective is to create a feedback loop where post-trade analysis directly architects pre-trade decisions.

Based on the data, a firm can implement a tiered dealer system.

- 
**Tier 1 Dealers (e.g. Dealer D, E)** ▴ Consistently low Leakage Index. They receive the majority of RFQ flow, especially for large or sensitive orders.

- 
**Tier 2 Dealers (e.g. Dealer A)** ▴ Moderate Leakage Index. They may be included in panels for more liquid assets or smaller sizes.

- 
**Tier 3 Dealers (e.g. Dealer B, C)** ▴ High Leakage Index. They are placed on a probationary list or removed from RFQ panels entirely. The firm may choose to engage in a direct conversation with these dealers, presenting the anonymized data as evidence of the issue.

This data-driven approach transforms the client-dealer relationship from one based on simple relationships to one governed by measurable, objective performance metrics. It re-asserts the client’s control over their information and [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Architecting a System of Trust

The analytical framework for detecting information leakage is ultimately an exercise in architecting trust. The RFQ protocol operates on an implicit agreement that valuable information will be handled with discretion. [Post-trade reversion analysis provides](https://prime.greeks.live/question/how-does-post-trade-reversion-analysis-inform-future-counterparty-selection-for-block-trades/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) the means to verify this trust quantitatively. It transforms the abstract concept of leakage into a measurable Key Performance Indicator for each dealer relationship.

Viewing this process through a systemic lens reveals that execution quality is an output of the system’s design. A trading desk that relies solely on relationships or perceived dealer strengths without a quantitative verification loop is operating with an incomplete architecture. The data from [reversion analysis provides](https://prime.greeks.live/question/how-does-a-market-makers-inventory-position-influence-the-quotes-it-provides-to-clients/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) the feedback mechanism necessary to evolve the system, making it more robust and resilient against the costly friction of information leakage. The insights gained are components in a larger intelligence system, one that empowers a firm to exert precise control over its market footprint and achieve a superior operational framework.

Dealers who consistently exhibit high leakage signatures can be downgraded or removed from panels for sensitive trades. Conversely, dealers who demonstrate low reversion and respect for the protocol's integrity are elevated and receive more order flow. The table below outlines the strategic shift from a basic TCA approach to a sophisticated leakage detection framework."
