## Concept

The decision to route an order to a dark venue is predicated on a foundational trade-off between the potential for price improvement and the risk of [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Your core operational challenge is not simply executing a trade, but preserving the integrity of your strategy in an environment of incomplete information. [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA), in its most evolved form, serves as the system-level diagnostic tool to quantify this trade-off. It moves the measurement of execution quality from a simple post-trade report to a real-time, dynamic assessment of venue toxicity.

The central problem in [dark venues](https://prime.greeks.live/area/dark-venues/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is [adverse selection](https://prime.greeks.live/area/adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which is the systemic risk that your counterparty possesses superior information. When you buy, they know the price is about to rise; when you sell, they know it is about to fall. This information asymmetry manifests as a direct cost, systematically eroding execution alpha.

Dark pools were architected to minimize the [market impact](https://prime.greeks.live/area/market-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) of large orders by shielding them from the view of predatory traders in lit markets. This opacity, however, creates its own distinct set of risks. The primary mechanism at play is participant self-selection. [Uninformed liquidity](https://prime.greeks.live/question/can-reversion-analysis-be-used-to-differentiate-between-informed-and-uninformed-liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) traders, such as passive index funds or those with non-urgent hedging needs, are drawn to dark pools by the promise of midpoint execution and lower explicit costs.

Informed traders, armed with short-term alpha signals, follow this uninformed flow into the dark, seeking to trade against it. The result is a complex ecosystem where the concentration of informed versus [uninformed order flow](https://prime.greeks.live/area/uninformed-order-flow/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) determines a venue’s level of [adverse selection risk](https://prime.greeks.live/area/adverse-selection-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). A venue saturated with uninformed liquidity offers a safe harbor. A venue where informed traders can consistently find and trade against that liquidity becomes a toxic environment, imposing significant hidden costs on unsuspecting participants.

## What Is the Core Mechanism of Adverse Selection?

The core mechanism of adverse selection in [dark pools](https://prime.greeks.live/area/dark-pools/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is the exploitation of information asymmetry enabled by the venue’s lack of pre-trade transparency. An [informed trader](https://prime.greeks.live/question/how-does-signal-strength-determine-an-informed-traders-venue-choice/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s primary asset is their private information about an asset’s future value. A dark pool provides a unique environment to monetize this information. Because orders are un-displayed, an informed trader can place a large, aggressive order to sweep available liquidity without signaling their intent to the broader market and causing the price to move against them before the order is complete.

Uninformed participants, by definition, place orders without this foresight. They are effectively posting blind liquidity that the informed trader can selectively execute against.

This dynamic is often described as a “[cream-skimming](https://prime.greeks.live/area/cream-skimming/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” effect. Dark pools can attract the most benign, uninformed order flow away from lit markets. This migration leaves the lit markets with a higher concentration of [informed traders](https://prime.greeks.live/area/informed-traders/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), potentially widening their bid-ask spreads.

Simultaneously, within the dark venue itself, the informed traders who have followed the uninformed flow are able to “skim” this liquidity, executing trades that are consistently profitable for them and consistently costly for their counterparties. The measurement of this cost is the primary function of a sophisticated TCA program.

## The Paradox of Dark Liquidity

The paradox of dark liquidity is that the very feature designed to protect an order ▴ its invisibility ▴ also makes it vulnerable. In a [lit market](https://prime.greeks.live/area/lit-market/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the order book provides a degree of protection. A large order will be met by a visible wall of bids or offers, and the [price impact](https://prime.greeks.live/area/price-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) can be observed and managed in real time. In a dark pool, a large passive order may be “pinged” by small, exploratory orders from algorithmic traders attempting to detect its presence.

Once discovered, the informed algorithm can [trade against](https://prime.greeks.live/question/can-post-trade-mark-out-analysis-provide-a-definitive-measure-of-an-algorithms-effectiveness-against-adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) it, or worse, use that information to establish a position on a lit market ahead of the large order’s eventual execution. This information leakage is a primary driver of [adverse selection costs](https://prime.greeks.live/question/how-does-client-anonymity-specifically-impact-a-dealers-adverse-selection-costs/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

Furthermore, the probability of execution itself becomes a source of information. Informed traders, all possessing similar signals, tend to cluster on one side of the market. This creates a higher execution risk for them in a [dark pool](https://prime.greeks.live/area/dark-pool/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), as there may be insufficient liquidity on the other side. Consequently, informed traders with very strong signals may favor the certainty of execution on a [lit exchange](https://prime.greeks.live/area/lit-exchange/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

This leads to a sorting effect where traders with the most impactful information may trade on exchanges, while those with moderately strong signals attempt to leverage them in dark pools. A [TCA system](https://prime.greeks.live/area/tca-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) must therefore analyze not just the cost of filled orders, but also the opportunity cost of unfilled orders, as this can also be a signal of adverse [selection risk](https://prime.greeks.live/area/selection-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Strategy

A strategic framework for [measuring adverse selection](https://prime.greeks.live/question/how-does-the-analysis-of-losing-quotes-provide-a-control-group-for-measuring-adverse-selection-costs/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in dark venues requires elevating Transaction Cost Analysis from a historical reporting function to a forward-looking risk [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). The objective is to dissect execution data to reveal the subtle signatures of informed trading. This involves deploying a set of specific, highly granular metrics designed to quantify information leakage and its resulting costs. The strategy rests on the principle of comparative analysis, both over time and across different execution venues.

It is a process of systematic questioning ▴ Are our dark pool executions consistently followed by adverse [price movements](https://prime.greeks.live/question/how-does-order-book-imbalance-affect-short-term-price-movements/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)? Do certain pools exhibit higher toxicity than others? How does our [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in dark venues compare to that in lit markets for the same instrument?

## Adapting TCA Metrics for Dark Pool Analysis

Standard TCA metrics like Volume Weighted Average Price (VWAP) are insufficient for diagnosing adverse selection in dark pools. VWAP is a market-wide benchmark that can obscure the specific costs incurred at the moment of execution. A more precise approach requires metrics that are sensitive to the information environment at the microsecond level. The strategic shift is toward using the order’s [arrival price](https://prime.greeks.live/area/arrival-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) as the primary benchmark and analyzing short-term price movements immediately following the fill.

- 
**[Arrival Price Slippage](https://prime.greeks.live/question/can-a-liquidity-seeking-algorithm-achieve-a-better-price-than-the-arrival-price-benchmark/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** This is the foundational metric. It measures the difference between the execution price of an order and the market midpoint at the time the order was routed to the venue. For a buy order, a fill price above the arrival midpoint represents negative slippage (a cost). For a sell order, a fill below the midpoint is a cost. Systematically high slippage in a particular dark pool is a primary indicator of adverse selection.

- 
**[Post-Trade Price Reversion](https://prime.greeks.live/question/how-can-post-trade-price-reversion-be-used-as-a-proxy-for-measuring-information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** This is the most direct measure of adverse selection. It analyzes the movement of the market midpoint in the seconds and minutes after a trade is executed. If a buy order is consistently followed by the market price falling (reverting), it suggests the seller was uninformed. If the price continues to rise, it indicates the counterparty was informed, and the buyer has suffered adverse selection. The strategy is to measure this reversion across thousands of trades to identify statistically significant patterns.

- 
**Fill Rate Analysis** In dark pools, the probability of execution is a critical piece of information. A low fill rate for passive orders may indicate that informed traders are avoiding trading at that price, which can be a positive sign. Conversely, an unusually high fill rate, especially for a large order, followed by negative [price reversion](https://prime.greeks.live/area/price-reversion/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), suggests the order was targeted by an informed trader. The strategy involves correlating fill rates with [post-trade reversion](https://prime.greeks.live/area/post-trade-reversion/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to understand the context of each execution.

## The Comparative Venue Analysis Framework

No dark pool operates in a vacuum. Its performance and toxicity are relative to other available liquidity sources. A robust strategy involves a systematic comparison of execution quality [across different](https://prime.greeks.live/question/how-does-the-aggregated-inquiry-protocol-vary-across-different-asset-classes/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) venues for the same security. This creates a competitive marketplace for your [order flow](https://prime.greeks.live/area/order-flow/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and allows you to dynamically route orders to the venues offering the best execution quality at any given moment.

The framework is built on A/B testing principles. A large [parent order](https://prime.greeks.live/area/parent-order/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) can be sliced and simultaneously routed to multiple venues, including lit markets and several different dark pools. The TCA system then analyzes the performance of each slice using the metrics described above. This allows for a direct, apples-to-apples comparison of the adverse [selection costs](https://prime.greeks.live/question/what-are-the-primary-differences-between-measuring-hard-costs-and-soft-costs-of-data-silos/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in each venue.

The “cream-skimming” theory suggests that high levels of [dark pool trading](https://prime.greeks.live/area/dark-pool-trading/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in a stock can increase the adverse selection costs on [lit markets](https://prime.greeks.live/area/lit-markets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). A comparative analysis framework can test this hypothesis by monitoring the bid-ask spread and slippage on lit exchanges while routing significant volume to dark pools.

> A TCA strategy focused on adverse selection treats every fill as a hypothesis to be tested against subsequent market behavior.

The following table outlines a strategic comparison of two hypothetical dark pools based on key TCA metrics for a 100,000 share buy order in stock XYZ, sliced evenly between them.

| Metric | Dark Pool A (High Liquidity) | Dark Pool B (Niche Provider) | Strategic Interpretation |
| --- | --- | --- | --- |
| Arrival Price Slippage | +1.5 bps | +3.5 bps | Pool B shows significantly higher initial costs, suggesting a higher concentration of informed traders demanding compensation for their information. |
| Post-Trade Reversion (30s) | -0.5 bps (Slight Reversion) | +2.0 bps (Adverse Movement) | The price moved further against the order in Pool B, confirming the presence of informed counterparties. The slight reversion in Pool A suggests trading with other uninformed liquidity. |
| Fill Rate (Passive Slices) | 85% | 60% | The lower fill rate in Pool B could indicate that informed traders are less willing to provide passive liquidity, forcing aggressive orders to pay a higher price. |
| Average Trade Size | 250 shares | 1,500 shares | Pool B’s larger average trade size, combined with high slippage, is a strong warning sign of institutional informed traders targeting liquidity. |

## How Does Liquidity Affect Adverse Selection Strategy?

The liquidity profile of a stock fundamentally alters the strategy for measuring and managing adverse selection. The relationship between the volume of dark trading and its impact on [market quality](https://prime.greeks.live/area/market-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is non-linear and depends heavily on the stock’s liquidity. For highly [liquid stocks](https://prime.greeks.live/area/liquid-stocks/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), a smaller percentage of trading in dark pools can begin to negatively affect market quality. For less liquid stocks, dark pools can absorb a much larger percentage of the volume before adverse effects appear.

This reality requires a segmented strategy:

- 
**For Liquid Stocks** The risk of information leakage is high, as many professional traders are watching these names. The strategy should prioritize speed of execution and minimizing market impact. TCA should be monitored in near real-time to detect even small increases in toxicity. A lower threshold for routing away from a dark pool is necessary. The analysis in one study suggests a threshold of around 9% of total trading value in dark venues for the most liquid stocks before adverse selection increases.

- 
**For Illiquid Stocks** The primary challenge is sourcing liquidity. Dark pools can be essential for finding the other side of a large trade without causing massive price dislocation. The strategy can tolerate a higher proportion of volume in dark pools, with some research suggesting a threshold as high as 25%. The focus of TCA here is less on high-frequency intraday reversion and more on the overall cost savings compared to executing on a thin lit market. The risk is still present, but it is balanced against the significant cost of market impact in the primary market.

## Execution

The execution of a TCA program for measuring adverse selection is a matter of high-fidelity data engineering and quantitative discipline. It requires architecting a system that captures, processes, and analyzes trade data at a granular level, transforming raw execution records into actionable intelligence. This intelligence, in turn, feeds a dynamic [feedback loop](https://prime.greeks.live/area/feedback-loop/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that informs and refines the firm’s execution strategy, particularly the logic embedded within its [Smart Order Router](https://prime.greeks.live/area/smart-order-router/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (SOR). The ultimate goal is to create a learning system that automatically identifies and mitigates adverse selection risk in real time.

## The Operational Playbook

Implementing a robust TCA system for this purpose follows a clear, multi-stage operational sequence. Each step builds upon the last, from raw data acquisition to sophisticated analytical output.

- 
**Data Architecture and Capture** The foundation of any TCA system is a comprehensive and time-stamped record of the entire order lifecycle. This is not a trivial data collection exercise. It requires capturing FIX protocol messages for every order placement, modification, cancellation, and execution. Essential data points include:

<li>Unique Parent and [Child Order](https://prime.greeks.live/area/child-order/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) IDs

- Precise Timestamps (nanosecond precision is the institutional standard) for all order events

- Security Identifiers (e.g. ISIN, CUSIP)

- Order Parameters (Side, Size, Price, Order Type)

- Venue of Execution

- Fill Price and Quantity

- A synchronized feed of the National Best Bid and Offer (NBBO) and the consolidated market-wide trade tape.

</li>
- 
**Benchmark Calculation and Normalization** With the raw data captured, the next step is to calculate the relevant benchmarks for each child order. For [dark pool analysis](https://prime.greeks.live/area/dark-pool-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the most critical benchmark is the midpoint of the NBBO at the time the order was sent to the venue (Arrival Price). All execution costs, or slippage, are calculated relative to this price. This normalization allows for the comparison of executions across different times and market conditions.

- 
**Metric Computation Engine** This is the core analytical engine of the system. It processes the benchmarked trade data to compute the key performance indicators for adverse selection. This includes calculating Arrival [Price Slippage](https://prime.greeks.live/area/price-slippage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and more importantly, [Post-Trade Price](https://prime.greeks.live/question/how-can-post-trade-price-reversion-be-used-as-a-proxy-for-measuring-information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Reversion at various time intervals (e.g. 1, 5, 15, 30, and 60 seconds post-fill). The engine must be capable of aggregating these metrics by venue, by security, by strategy, and by time of day.

- 
**Pattern Recognition and Alerting** The final layer of the playbook is the interpretation of the data. The system should be configured to identify patterns of toxic behavior. For example, an automated alert could be triggered if a specific dark pool’s average 30-second post-trade [adverse price movement](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) for a particular stock exceeds a predefined threshold (e.g. 2 basis points) over a rolling time window. This allows traders to intervene and adjust routing logic manually or, in more advanced systems, allows the SOR to do so automatically.

## Quantitative Modeling and Data Analysis

The output of the TCA system must be presented in a way that reveals the underlying dynamics of [venue toxicity](https://prime.greeks.live/area/venue-toxicity/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The following tables provide examples of the kind of quantitative analysis required to unmask adverse selection. They represent the type of granular, evidence-based reporting that a well-architected system should produce.

**Table 1 ▴ Post-Trade Reversion Analysis by Venue**

This table analyzes the average post-fill price movement for buy orders in stock ABC across three different venues. A positive number indicates the [price moved further against](https://prime.greeks.live/question/how-does-central-clearing-further-reduce-risk-in-an-rfq-transaction/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) the buyer (adverse selection), while a negative number indicates price reversion in the buyer’s favor.

| Execution Venue | Average Slippage vs Arrival Mid (bps) | Post-Fill Price Change T+5s (bps) | Post-Fill Price Change T+30s (bps) | Post-Fill Price Change T+60s (bps) |
| --- | --- | --- | --- | --- |
| Lit Exchange (ARCA) | +0.8 | -0.2 | -0.5 | -0.7 |
| Dark Pool A | +1.2 | -0.4 | -0.6 | -0.9 |
| Dark Pool B | +2.5 | +1.5 | +2.8 | +3.4 |

The data clearly indicates that Dark Pool B is a highly toxic venue for this stock. Not only is the initial slippage significantly higher, but the price continues to move adversely after the fill, suggesting trades are consistently made with informed counterparties. Dark Pool A, by contrast, performs similarly to the lit exchange, suggesting it is a relatively safe venue.

> Effective execution is the result of a system that transforms post-trade data into pre-trade intelligence.

## Predictive Scenario Analysis

Consider a scenario where a portfolio manager needs to sell a 500,000 share block of a mid-cap technology stock, “TECH”. The stock has an average daily volume of 2 million shares, so this order represents 25% of the day’s volume and carries significant market impact risk. The execution trader’s objective is to minimize this impact and avoid signaling the large sell interest to the market.

The trader uses a sophisticated SOR that is integrated with the firm’s real-time TCA system. Initially, the SOR is configured to route 60% of the [child orders](https://prime.greeks.live/area/child-orders/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to a selection of dark pools and 40% to lit markets, posting passively to capture the spread. For the first 15 minutes of execution, the TCA dashboard shows the following:

- 
**Dark Pool A** ▴ [Fill rate](https://prime.greeks.live/area/fill-rate/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) of 20%, average slippage of -0.5 bps (favorable), and a [post-trade price movement](https://prime.greeks.live/question/how-can-post-trade-price-reversion-be-used-as-a-proxy-for-measuring-information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) of +0.2 bps (slight favorable reversion).

- 
**Dark Pool B** ▴ Fill rate of 40%, average slippage of -1.5 bps (favorable), but a post-trade price movement of -2.5 bps (highly adverse).

- 
**Lit Markets** ▴ Bid-ask spread has widened from 2 bps to 4 bps.

The TCA system immediately flags the performance of Dark Pool B. The high fill rate combined with the significant [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 is a classic signature of a predatory algorithm detecting the large sell order and trading ahead of it. The system identifies that counterparties in Pool B are selling and then watching the price drop further as more of the parent order is executed. The widening spread on the lit market confirms that information is leaking out. In response, the SOR, guided by the TCA feedback loop, automatically adjusts its logic.

It ceases all routing to Dark Pool B, increases the passive posting on Dark Pool A, and reduces the aggression on lit markets to allow the spread to recover. This dynamic adjustment, driven by quantitative evidence of adverse selection, directly minimizes the execution costs for the remainder of the order.

## System Integration and Technological Architecture

The seamless execution of this strategy depends on a tightly integrated technological architecture. The core components are the Order Management System (OMS), the Execution Management System (EMS) with its integrated SOR, and the TCA system. The flow of information must be continuous and in near real-time.

- 
**OMS to EMS** The process begins when the parent order is passed from the OMS to the EMS. The EMS is responsible for the trading strategy, breaking the parent order into smaller, manageable child orders.

- 
**EMS/SOR to Venues** The SOR within the EMS makes the micro-decision of where to route each child order. This decision is based on a set of rules, which in a sophisticated setup, are continuously updated by the TCA system.

- 
**Venues to [Data Capture](https://prime.greeks.live/area/data-capture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** As child orders are filled, execution reports are sent back via the FIX protocol. These, along with the market data feeds, are consumed by the TCA system’s data capture component.

- 
**TCA to SOR Feedback Loop** This is the most critical integration point. The TCA system analyzes the incoming execution and market data, calculating metrics like post-trade reversion in real-time. This analysis generates a “venue toxicity score.” The SOR is programmed to query these scores continuously, adjusting its routing table to favor venues with low toxicity scores and avoid those with high scores. This creates an adaptive execution algorithm that learns from the market’s response to its own actions. This feedback loop transforms the SOR from a static, rule-based engine into a dynamic, intelligent agent for minimizing adverse selection risk.

## Reflection

The architecture of your execution strategy defines your firm’s resilience to information leakage. The principles and models discussed provide a quantitative foundation for identifying and measuring the hidden costs of adverse selection. The critical introspection, however, moves beyond measurement to infrastructure. Does your current data capture and analysis framework possess the fidelity required to perform this level of diagnostics?

Is the feedback loop between your post-trade analysis and your pre-trade routing logic fully integrated and automated? Answering these questions reveals the true operational readiness of your firm to navigate the complex, opaque environments of modern market structure and secure a durable execution edge.

                "text": "The core mechanism of adverse selection in dark pools is the exploitation of information asymmetry enabled by the venue's lack of pre-trade transparency. An informed trader's primary asset is their private information about an asset's future value. A dark pool provides a unique environment to monetize this information. Because orders are un-displayed, an informed trader can place a large, aggressive order to sweep available liquidity without signaling their intent to the broader market and causing the price to move against them before the order is complete. Uninformed participants, by definition, place orders without this foresight. They are effectively posting blind liquidity that the informed trader can selectively execute against."

                "@type": "Answer",
                "text": "The liquidity profile of a stock fundamentally alters the strategy for measuring and managing adverse selection. The relationship between the volume of dark trading and its impact on market quality is non-linear and depends heavily on the stock's liquidity. For highly liquid stocks, a smaller percentage of trading in dark pools can begin to negatively affect market quality. For less liquid stocks, dark pools can absorb a much larger percentage of the volume before adverse effects appear."
