## Concept

[Post-trade markout](https://prime.greeks.live/area/post-trade-markout/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) analysis operates as a forensic accounting tool for the physics of market impact. It directly quantifies the cost of [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) by measuring the price trajectory immediately following an execution. The core principle rests on a simple, observable phenomenon ▴ when a trader’s intention is broadcast, whether intentionally or through the digital exhaust of an order, the market reacts. This reaction is not random noise; it is a directed response from other participants who have decoded the signal of your trading intent.

[Markout analysis](https://prime.greeks.live/area/markout-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) isolates and prices this response. It functions by establishing a baseline price at the moment of a fill and then tracking the market’s movement away from that baseline over specified time intervals. A consistent, adverse price movement ▴ prices rising after a buy or falling after a sell ▴ is the signature of information leakage. The magnitude of this movement, when multiplied by the volume of subsequent fills, provides a direct, empirical measure of the financial cost incurred due to that leakage.

The distinction between information leakage and [adverse selection](https://prime.greeks.live/area/adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a critical architectural point in this analysis. Adverse selection occurs when you trade with a counterparty who possesses superior information about the security’s fundamental value, independent of your own order. It is a cost arising from the inherent information asymmetry in the market. Information leakage, conversely, is the cost you impose upon your own order.

It is the market impact created as a consequence of your trading activity, signaling your intentions to others who then trade in front of your remaining order size. Markout analysis, when properly constructed, is uniquely capable of distinguishing between these two forces. It achieves this by focusing on the price action immediately following the initial fills of a large [parent order](https://prime.greeks.live/area/parent-order/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The price behavior in these moments is less about long-term fundamentals and more about the short-term [supply and demand](https://prime.greeks.live/area/supply-and-demand/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) imbalance created by the market’s awareness of a large, motivated participant.

> Markout analysis provides a precise financial measure of market reaction to a trade, thereby quantifying the economic damage of leaked trading intentions.

This process is fundamentally about causality. A standard [post-trade analysis](https://prime.greeks.live/area/post-trade-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) might reveal that an order experienced high costs, but it often struggles to attribute the cause. It might be market volatility, a liquidity event, or adverse selection. Markout analysis provides a more granular diagnosis.

By tracking the price path from the first fill onward, a clear pattern can emerge. If the first few “child” orders of a large “parent” order execute at a good price, but subsequent fills occur at progressively worse prices, and the [markout curve](https://prime.greeks.live/area/markout-curve/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) shows a distinct trend against the trader’s position, the cause is rarely coincidence. It is the system reacting to the information released by those initial fills. The cost of this reaction is the information [leakage cost](https://prime.greeks.live/area/leakage-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), a tax on predictability. Quantifying this tax is the primary function of markout analysis.

The analysis treats every trade as a release of information. The central question it answers is ▴ What was the price of that information? By measuring the price change in the seconds and minutes after a trade, we are observing the market’s digestion of that new data point. A large buy order that is detected by other participants will attract other buyers, driving the price up and increasing the cost for the original trader to complete their order.

The markout captures the exact cost of this induced demand. It moves the conversation from a vague concern about “being seen” in the market to a concrete, data-driven discussion about execution strategy, venue selection, and algorithmic choice, all grounded in the measurable financial impact of information control.

## Strategy

Developing a strategic framework for markout analysis requires a shift in perspective. The goal is to build a system that moves beyond simple performance reporting to become a diagnostic engine for [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This engine must be calibrated to isolate the specific signal of information leakage from the background noise of general market volatility and baseline adverse selection. The architecture of such a framework rests on several key strategic decisions regarding its construction and application.

## Designing the Analytical Framework

The effectiveness of markout analysis is determined by the precision of its design. The parameters chosen for the analysis dictate its ability to accurately identify and quantify leakage. A robust strategy involves a multi-layered approach, combining different time horizons and benchmarking techniques to build a comprehensive picture of execution costs.

Key strategic parameters include:

- **Time Horizons** ▴ The selection of time intervals for markout calculation is a critical decision. Short-term markouts (e.g. 1, 5, 15 seconds) are highly sensitive to the immediate impact of information leakage, capturing the high-frequency responses to a trade. Longer-term markouts (e.g. 1, 5, 15 minutes) help to understand the persistence of the impact and can help differentiate temporary liquidity effects from more permanent price adjustments driven by leakage. A comprehensive strategy uses a spectrum of time horizons to create a full “markout curve.”

- **Benchmarking** ▴ The choice of a benchmark price is fundamental. While the execution price itself is the most common starting point, more sophisticated approaches use the prevailing mid-quote at the time of the trade. This helps to normalize for the bid-ask spread and provides a more accurate measure of the market’s movement. Comparing the markout of a specific trade to a universe of similar trades (e.g. same stock, same time of day, similar size) provides the context needed to determine if the observed impact was unusual.

- **Order-Level vs. Fill-Level Analysis** ▴ A purely fill-based analysis can be misleading. While it measures the adverse selection on individual executions, it fails to capture the cumulative damage of leakage across a large parent order. A strategic framework must focus on the parent order. The analysis should track the markout from the first fill of the parent order through to its completion. This perspective reveals how the information released by early fills impacts the execution cost of later fills, which is the very definition of information leakage.

- **Venue and Algorithm Analysis** ▴ The ultimate strategic goal is to use the analysis to make better execution decisions. The framework must be designed to compare the performance of different trading venues, algorithms, and brokers. By segmenting the markout data by these variables, a trader can identify which pathways are “leaky” and which are secure. This allows for a data-driven approach to routing orders and selecting execution strategies that minimize market footprint.

## Interpreting the Markout Signal

Once the framework is in place, the next strategic challenge is the correct interpretation of its output. Markout curves are rich with information, and understanding their shape is key to diagnosing the nature of execution costs.

> A sharply trending markout curve following a trade is the clearest quantitative evidence of information leakage at work.

Different curve shapes imply different causes:

- **A Steep, Sustained Trend** ▴ If, after a buy order, the markout curve shows a sharp and continuous rise, it is a strong indicator of information leakage. This shape suggests that other market participants detected the initial trade and began trading in the same direction, pushing the price away from the trader and increasing the cost of completing the parent order.

- **A “V” Shape” (Mean Reversion)** ▴ If the price moves against the trader initially but then reverts back toward the original execution price, this often signals a temporary liquidity cost. The trade may have consumed the immediately available liquidity, causing a temporary price dip (for a sell) or spike (for a buy), which then recovered as liquidity was replenished. This is a cost, but it is a liquidity cost, not necessarily a leakage cost.

- **A Flat Curve** ▴ A flat markout curve suggests the trade had minimal lasting impact on the price. This is the ideal outcome, indicating that the trade was absorbed by the market without signaling the trader’s larger intentions. It suggests a secure execution with low information leakage.

By categorizing trades based on their markout curve shapes and correlating these shapes with venues, algorithms, and other trading parameters, a firm can build a sophisticated, evidence-based strategy for minimizing the quantifiable cost of information leakage.

## Execution

The execution of post-trade markout analysis is a quantitative and data-intensive process. It requires a robust technological architecture, a precise calculation methodology, and a disciplined approach to interpretation. This section provides a detailed operational playbook for implementing this analysis to quantify the cost of information leakage.

## The Operational Playbook Data Architecture and Requirements

The foundation of any credible markout analysis is the quality and granularity of the data. The system must capture and synchronize multiple data streams to reconstruct the trading environment with high fidelity. Without this, the analysis will be flawed.

- **Trade and Order Data Capture** ▴ The system must log every detail of the firm’s own orders. This includes the parent order details (symbol, side, size, order type, time of entry) and the details of all child orders and their corresponding fills (execution price, size, timestamp, venue). High-precision timestamps, ideally at the microsecond or nanosecond level, are essential.

- **Market Data Acquisition** ▴ Alongside the firm’s own trading data, a complete record of the market data is required. This includes top-of-book (NBBO) quotes and, ideally, depth-of-book data for the traded instrument. This data must be timestamped with the same precision as the trade data to allow for accurate synchronization.

- **Data Synchronization and Storage** ▴ A centralized data warehouse or “tick database” is necessary to store and synchronize these datasets. The core technical challenge is to create a unified timeline of events, allowing an analyst to query the state of the market (e.g. the mid-quote) at the exact moment a fill occurred.

## Quantitative Modeling and Data Analysis

With the data architecture in place, the next step is the calculation engine. The core calculation is the markout itself, which is performed for each fill and then aggregated to create markout curves.

The formula for a post-trade markout is:

Markout(t) = Side (BenchmarkPrice(t) - ExecutionPrice)

Where:

- **t** ▴ The time interval post-execution (e.g. 1 second, 5 seconds).

- **Side** ▴ +1 for a buy order, -1 for a sell order. This ensures that a positive markout value always represents an adverse price movement (a cost).

- **BenchmarkPrice(t)** ▴ The market price at time ExecutionTime + t. This is typically the mid-point of the National Best Bid and Offer (NBBO).

- **ExecutionPrice** ▴ The price at which the specific fill occurred.

This calculation is repeated for multiple time intervals and for every fill within a parent order. The results are then typically averaged across many orders to produce a characteristic markout curve for a particular strategy, venue, or algorithm.

## How Is the Financial Cost Calculated?

The markout value itself represents a price movement per share. To translate this into a total dollar cost of information leakage for a parent order, the following calculation is performed:

Leakage Cost = Σ 

This involves a more complex, fill-by-fill attribution. For each fill within a parent order, its markout performance is calculated. This markout is then multiplied by the number of shares remaining to be executed in the parent order.

This attributes the [price impact](https://prime.greeks.live/area/price-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) caused by one fill to the cost of all subsequent fills. Summing this value across all fills in the parent order gives a total leakage cost.

The following table provides a simplified example of this calculation for a 10,000-share buy order.

| Fill Number | Fill Size | Fill Price | Mid-Price 5s After Fill | Markout (5s) | Remaining Size | Attributed Leakage Cost |
| --- | --- | --- | --- | --- | --- | --- |
| 1 | 1,000 | $100.00 | $100.02 | $0.02 | 9,000 | $180.00 |
| 2 | 1,000 | $100.01 | $100.04 | $0.03 | 8,000 | $240.00 |
| 3 | 1,000 | $100.03 | $100.06 | $0.03 | 7,000 | $210.00 |
| 4 | 1,000 | $100.05 | $100.08 | $0.03 | 6,000 | $180.00 |
| 5 | 6,000 | $100.07 | $100.10 | $0.03 | 0 | $0.00 |
| Total | 10,000 | – | – | – | – | $810.00 |

## Predictive Scenario Analysis Comparing Execution Venues

The primary application of this analysis is to drive better routing decisions. By segmenting markout data by the venue where fills occurred, a firm can build a quantitative profile of the information leakage costs associated with each destination. This allows for a direct, evidence-based comparison.

Consider a scenario where a trading firm wants to compare two [dark pools](https://prime.greeks.live/area/dark-pools/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), Venue A and Venue B, for executing large-cap equity orders. After routing similar orders to both venues over a period of one month, the firm aggregates the markout analysis results.

> The choice of execution venue is a primary determinant of information leakage; markout analysis makes the cost of this choice transparent.

The comparison might yield a table like the following:

| Metric | Venue A | Venue B | Interpretation |
| --- | --- | --- | --- |
| Total Volume Executed | 10,000,000 shares | 10,500,000 shares | Similar flow sent to both venues. |
| Average 1-Second Markout | $0.0015 | $0.0005 | Venue B shows less immediate adverse price movement. |
| Average 30-Second Markout | $0.0070 | $0.0015 | The price impact on Venue A is persistent and growing, a strong sign of leakage. Venue B’s impact is much lower. |
| Average 5-Minute Markout | $0.0120 | $0.0020 | Confirms the long-term leakage signal from Venue A. |
| Calculated Leakage Cost per Share | $0.0095 | $0.0018 | The total implied cost attributed to leakage is over 5x higher on Venue A. |
| Total Estimated Leakage Cost | $95,000 | $18,900 | The financial consequence of the routing decision becomes clear. |

In this scenario, the analysis provides a clear, quantitative justification for shifting flow away from Venue A and towards Venue B. Venue A is demonstrably “leakier,” and this leakage has a direct, measurable financial cost. This is the ultimate function of markout analysis ▴ to transform the abstract concept of information leakage into a concrete input for strategic and tactical trading decisions.

## What Does Your Execution Architecture Reveal about Your Strategy?

The data presented by a rigorous markout analysis does more than quantify a cost. It holds up a mirror to a firm’s entire trading operation. The patterns of information leakage revealed by this process are a direct reflection of the choices embedded in the execution architecture ▴ the algorithms selected, the venues prioritized, the speed at which orders are placed, and the sizes displayed to the market. A consistently high leakage cost is a systemic output, pointing to a potential misalignment between trading intent and execution reality.

Viewing this analysis not as a report card but as a diagnostic tool allows for a more profound level of introspection. It prompts a series of critical questions. Are our algorithmic choices truly optimizing for minimal impact, or are they designed for speed at the expense of information control? Do our venue routing tables reflect a deep understanding of the toxicity and signaling risk of each destination, or are they based on simple metrics like fill rates and explicit fees?

The markout curve is the market’s own commentary on these decisions. Learning to interpret its language is fundamental to evolving from a reactive participant to a strategic architect of one’s own execution.

The patterns of information leakage revealed by this process are a direct reflection of the choices embedded in the execution architecture\u2014the algorithms selected, the venues prioritized, the speed at which orders are placed, and the sizes displayed to the market. A consistently high leakage cost is a systemic output, pointing to a potential misalignment between trading intent and execution reality."
