## Concept

The architecture of a market is a system of protocols that governs the flow of information. Within this system, the choice between revealing or concealing the identity of participants in a [Central Limit Order Book](https://prime.greeks.live/area/central-limit-order-book/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (CLOB) constitutes a fundamental design decision with profound and cascading effects on the market’s primary function ▴ price discovery. Anonymity is an engineered condition. It is a deliberate calibration of the [pre-trade transparency](https://prime.greeks.live/area/pre-trade-transparency/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) parameters within the market’s operating system.

The core purpose of this calibration is to control [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), a critical operational concern for any institutional participant executing substantial orders. When an institution’s identity or even its broker’s identity is attached to an order, that information is a signal. Other market participants can interpret this signal, anticipate the institution’s subsequent actions, and trade ahead of the larger [order flow](https://prime.greeks.live/area/order-flow/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), creating adverse price movement. This phenomenon, known as signaling risk or information leakage, directly increases transaction costs.

Anonymity within the CLOB directly addresses this vulnerability. By stripping identifying data from the order messages before they are displayed to the public book, the system severs the link between a specific participant and their expressed intent to trade. This creates a more homogenous and less transparent environment at the pre-trade level. The [order book](https://prime.greeks.live/area/order-book/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) still displays price and size, the elemental components of liquidity.

The critical piece of information that is removed is the “who.” This seemingly simple omission fundamentally alters the strategic interactions between market participants. It forces them to evaluate the order book based purely on the objective data of bids and asks, rather than on the perceived intentions or reputation of the entity behind those orders. The result is a change in the texture of liquidity and the mechanics of how new information is impounded into the asset’s price.

> Anonymity in a CLOB is an architectural choice designed to mitigate information leakage by removing participant identifiers from pre-trade order flow.

The process of [price discovery](https://prime.greeks.live/area/price-discovery/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) itself is the mechanism by which a market integrates new information to arrive at a consensus valuation for an asset. In a fully transparent CLOB, this process is influenced by both the explicit information in the order book (prices and sizes) and the implicit information derived from trader identities. An institutional order from a well-regarded pension fund might be interpreted differently than an order from a high-frequency trading firm, even if both orders are for the same size and price. The former might signal a long-term valuation belief, while the latter might suggest a short-term liquidity-providing strategy.

This layer of social and reputational data can accelerate price discovery when the identified traders are perceived as being highly informed. It can also, however, introduce noise and create opportunities for predatory trading strategies that target specific participants.

When anonymity is introduced, this implicit information channel is shut down. Price discovery must then proceed solely on the basis of the anonymous order flow. Research on the effects of switching to anonymous trading, such as the study of the Euronext Paris exchange, shows a complex series of trade-offs. Anonymity can lead to tighter bid-ask spreads and increased depth at the best quotes because liquidity providers, particularly large institutions, feel safer posting aggressive [limit orders](https://prime.greeks.live/area/limit-orders/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) without revealing their hand.

They are less concerned about being “picked off” by opportunistic traders who detect their presence. This improved liquidity at the top of the book can, on the surface, suggest a more efficient market. However, this very same condition can also alter the quality of the information embedded in the order book. The bid-ask spread in a transparent market often serves as a signal for near-term volatility; a wider spread might indicate that informed traders are cautious.

In an anonymous market, this signal can become weaker because the spread is influenced more by general liquidity provision and less by the specific actions of traders with superior information about volatility. The price discovery process may become less efficient in conveying information about future price movements, even as the cost of immediate execution appears to fall. The system gains surface-level liquidity at the potential cost of informational depth. This is the central paradox of anonymity ▴ it protects informed traders, which encourages them to participate more fully, but it simultaneously makes it harder for the market as a whole to learn from their actions.

## Strategy

For an [institutional trading](https://prime.greeks.live/area/institutional-trading/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) desk, the existence of anonymous trading protocols within a CLOB is a strategic tool. The decision of where and how to route an order is a function of the order’s characteristics, the institution’s objectives, and the prevailing market conditions. The primary strategic benefit conferred by anonymity is the management of execution footprint. A large order, if executed carelessly on a fully transparent venue, leaves a trail that can be easily detected by algorithmic and human traders.

This detection leads to [market impact](https://prime.greeks.live/area/market-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the adverse price movement caused by the trading activity itself. Anonymity is a structural defense against this impact.

The strategic framework for leveraging anonymity involves a multi-faceted analysis of the trade-offs between information leakage, execution speed, and potential [adverse selection](https://prime.greeks.live/area/adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Adverse selection is the risk of trading with a counterparty who possesses superior information. In an anonymous environment, while you are protected from revealing your own intentions, you also have less information about the intentions of those on the other side of your trade.

A large sell order that appears on an anonymous book could be from a similarly large institution rebalancing its portfolio, or it could be from an informed trader acting on negative private information. The inability to distinguish between these two scenarios is the price of your own concealment.

## Venue Selection and Order Routing Logic

A sophisticated trading system does not treat all venues as equal. It employs a dynamic order routing logic that considers the level of pre-trade transparency as a key parameter. This logic is often encapsulated in 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 achieve optimal execution by intelligently splitting and sending orders to various trading venues.

- **For “vanilla” or small-sized orders** ▴ These orders carry minimal information content and are less susceptible to market impact. The primary goal is speed and cost minimization. An SOR might prioritize routing these orders to the venue with the tightest spread and lowest fees, regardless of its [anonymity protocol](https://prime.greeks.live/area/anonymity-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The information leakage risk is negligible.

- **For large, uninformed orders** ▴ Consider a large index fund that must rebalance its portfolio due to fund inflows. The trade is large, but it is not based on any private, alpha-generating information. The primary risk here is market impact. The strategy is to minimize footprint. The SOR would be configured to heavily favor [anonymous venues](https://prime.greeks.live/area/anonymous-venues/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and [dark pools](https://prime.greeks.live/area/dark-pools/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). It would slice the large parent order into many smaller child orders and release them over time to avoid creating a noticeable bulge in liquidity on any single venue.

- **For large, informed orders** ▴ This is the most complex scenario. The trader possesses alpha-generating information that they wish to express without alerting the market. Anonymity is critical, but so is the risk of adverse selection. The strategy here is more nuanced. The trader might use a mix of anonymous CLOBs and other liquidity sources like Request for Quote (RFQ) systems. The RFQ protocol allows them to selectively solicit quotes from trusted liquidity providers, maintaining discretion while gaining price certainty for a portion of the trade. The remaining part of the order might be worked slowly on an anonymous CLOB, with the trader’s own algorithms monitoring for signs of adverse selection (e.g. the market moving away from them immediately after a fill).

## How Does Anonymity Affect Quoting Strategy?

From the perspective of a liquidity provider or market maker, anonymity changes the calculus of placing limit orders. In a transparent market, a market maker might adjust their quotes based on which firm is seeking liquidity. They might offer a tighter spread to a client with whom they have a positive trading history and a wider spread to a firm known for aggressive, informed trading. Anonymity removes this ability.

All incoming market orders must be treated as if they could be from an informed trader. This uncertainty can lead to market makers widening their spreads to compensate for the increased risk of adverse selection. However, academic studies and market events, like the switch to anonymity on the Australian Stock Exchange, have shown that anonymity can also empower institutional investors to post more aggressive, informative limit orders themselves, effectively competing with traditional market makers and contributing to narrower spreads at the top of book. This creates a dynamic tension ▴ the risk of the unknown informed taker versus the benefit of the unknown informed maker.

> The strategic use of anonymity balances the need to reduce one’s own information footprint against the increased risk of trading with an informed counterparty.

The table below outlines a simplified strategic framework for venue selection based on order characteristics and market state, illustrating the role of anonymity as a key decision parameter.

| Order Type & Objective | Primary Risk | Dominant Venue Strategy | Rationale |
| --- | --- | --- | --- |
| Small Market Order (Urgent) | Slippage | Lit CLOB (Transparent or Anonymous) | The priority is immediate execution at the best available price. Information leakage is not a concern. |
| Large Passive Order (e.g. Index Fund) | Market Impact | Anonymous CLOB / Dark Pools | The primary goal is to hide the full size of the order and minimize the execution footprint by blending in with other order flow. |
| Large Informed Order (Alpha-Driven) | Information Leakage & Adverse Selection | Hybrid ▴ RFQ + Anonymous CLOB | A portion is executed via discreet RFQ to secure a price, with the remainder worked carefully on anonymous venues to capture alpha without signaling intent. |
| Algorithmic Liquidity Provision | Adverse Selection | Varies (Model Dependent) | Strategy depends on the model’s ability to infer information from anonymous flow. May involve wider spreads or faster quote withdrawal in volatile conditions. |

Ultimately, the strategy for navigating anonymous markets is one of information management. An institutional desk must architect its execution systems to treat anonymity not as a binary state, but as a continuous variable within a fragmented liquidity landscape. The goal is to build a process that selectively reveals information when it is advantageous (or harmless) to do so, and rigorously conceals it when the order carries a high information payload. This requires sophisticated technology, a deep understanding of [market microstructure](https://prime.greeks.live/area/market-microstructure/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and a dynamic approach to execution that adapts to the specific characteristics of each trade.

## Execution

The execution of trades within a market ecosystem that includes anonymous venues is a matter of precise operational protocol and quantitative rigor. For the institutional trader, the theoretical benefits of anonymity must be translated into tangible execution quality, measured through post-trade analytics like [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA). This requires a deep integration of market structure knowledge, quantitative modeling, and technological infrastructure. The execution framework is not a single action but a complete process, from pre-trade analysis to the final settlement of the trade, designed to navigate the complex trade-offs inherent in anonymous trading.

## The Operational Playbook

An effective [execution strategy](https://prime.greeks.live/area/execution-strategy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for leveraging anonymity is systematic and repeatable. It can be codified into an operational playbook that guides traders through the lifecycle of a large order. This playbook provides a structured process for decision-making, ensuring that choices are deliberate and aligned with the overarching goal of minimizing costs and preserving alpha.

- **Pre-Trade Analysis & Parameterization**

<li>**Order Characterization** ▴ The first step is to classify the order. Is it informed or uninformed? What is its urgency? The order’s size relative to the asset’s average daily volume (ADV) is a critical metric. An order representing 10% of ADV requires a vastly different handling protocol than one representing 0.1%.

- **Liquidity Mapping** ▴ The trader must have a real-time view of the available liquidity across all accessible venues, both lit and dark. This includes the displayed depth on anonymous and transparent CLOBs, as well as potential liquidity in dark pools and from RFQ providers. The system should quantify the “texture” of this liquidity ▴ how stable is the quote? What is the average fill size?

- **Volatility & Event Assessment** ▴ The current market volatility regime must be assessed. In high-volatility environments, the risk of adverse selection in anonymous venues increases. The trader must also be aware of any pending news or economic data releases that could impact the asset’s price.

- **Algorithm Selection** ▴ Based on the above inputs, the trader selects an appropriate execution algorithm. Common choices include Volume Weighted [Average Price](https://prime.greeks.live/guide/the-definitive-guide-to-beating-the-markets-average-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (VWAP), Time Weighted Average Price (TWAP), or more sophisticated [implementation shortfall](https://prime.greeks.live/area/implementation-shortfall/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) algorithms. The key is to parameterize the algorithm to control its interaction with anonymous venues. For instance, an implementation shortfall algorithm can be tuned to be more or less aggressive based on the perceived risk of information leakage.

</li>
- **Execution Phase & In-Flight Adjustments**

<li>**Order Slicing & Routing** ▴ The parent order is broken down into smaller child orders. The Smart Order Router (SOR) is the core technology here, executing the routing logic defined in the pre-trade phase. For a sensitive order, the SOR might be configured to send a maximum of 1% of the displayed size to any single [anonymous venue](https://prime.greeks.live/question/how-does-an-rfq-platform-differentiate-between-on-venue-and-off-venue-reporting-obligations/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) at a time to avoid being detected.

- **Monitoring Information Leakage** ▴ The execution desk must actively monitor for signs that their order is being detected. This involves watching for abnormal price movements or changes in liquidity on other venues that are correlated with their own fills. If the market consistently moves away immediately after a child order is filled on an anonymous venue, it may be a sign of a “toxic” environment where other participants are sniffing out the order flow.

- **Dynamic Re-routing** ▴ The playbook must allow for in-flight adjustments. If an anonymous venue appears toxic or fails to provide meaningful fills, the trader or the algorithm should be able to dynamically down-weight or remove that venue from the SOR’s routing table and re-allocate the remaining portion of the order to other sources of liquidity, such as a different anonymous pool or by initiating an RFQ.

</li>
- **Post-Trade Analysis (TCA)**

<li>**Performance Benchmarking** ▴ The execution performance is measured against a pre-defined benchmark. For an uninformed order, this might be the VWAP over the execution period. For an informed order, the benchmark is the [arrival price](https://prime.greeks.live/area/arrival-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (the price at the moment the decision to trade was made). The difference between the average execution price and the benchmark price is the implementation shortfall, or [transaction cost](https://prime.greeks.live/area/transaction-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

- **[Venue Analysis](https://prime.greeks.live/area/venue-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ A critical component of TCA is analyzing the performance of individual execution venues. The system should break down the execution costs by venue. Which anonymous venues provided the best price improvement? Which had the highest rates of adverse selection (measured by post-fill price reversion)? This data-driven feedback loop is essential for refining the SOR’s logic for future trades.

- **Refining the Playbook** ▴ The results of the TCA are used to update and improve the operational playbook itself. If data shows that a particular anonymous venue consistently performs poorly for orders above a certain size, the playbook is updated to reflect this, perhaps by setting stricter limits on its use.

## Quantitative Modeling and Data Analysis

The execution playbook is underpinned by quantitative models that seek to formalize the trade-offs involved. These models are not black boxes; they are analytical tools that provide a structured way to think about risk and cost. The data they produce informs every stage of the trading process.

![Translucent, overlapping geometric shapes symbolize dynamic liquidity aggregation within an institutional grade RFQ protocol.

## What Is the True Cost of Execution?

The central model in institutional trading is the Implementation Shortfall model. It breaks down the total cost of trading into several components, allowing for a granular analysis of execution strategy. Anonymity’s primary role is to reduce the “Market Impact” component of this cost.

Consider the execution of a 500,000 share buy order for a stock with an arrival price of $100.00. The table below provides a hypothetical TCA report comparing two execution strategies ▴ one relying heavily on a lit, transparent CLOB, and a hybrid strategy leveraging anonymous venues.

| TCA Component | Strategy A ▴ Lit CLOB Focus | Strategy B ▴ Hybrid (Anonymous + Lit) | Formula / Explanation |
| --- | --- | --- | --- |
| Arrival Price | $100.00 | $100.00 | Price at time of order placement (T=0). |
| Average Execution Price | $100.15 | $100.06 | Volume-weighted average price of all fills. |
| Benchmark Price (VWAP) | $100.10 | $100.10 | VWAP of the stock during the execution period. |
| Implementation Shortfall (Total Cost) | $75,000 (15 bps) | $30,000 (6 bps) | (Avg Exec Price – Arrival Price) Size |
| — Cost Breakdown — | | | |
| Market Impact Cost | $25,000 (5 bps) | $5,000 (1 bp) | (VWAP – Arrival Price) Size. The portion of price movement attributable to general market drift vs. your own trading. Strategy A’s aggressive lit trading pushed the VWAP up. |
| Timing / Opportunity Cost | $25,000 (5 bps) | -$20,000 (-4 bps) | (Benchmark Price – Arrival Price) Unexecuted Shares. This cost was not incurred as the order was fully filled. |
| Execution Cost (Slippage) | $25,000 (5 bps) | $25,000 (5 bps) | (Avg Exec Price – VWAP) Size. Measures how well the execution beat or missed the average price. Strategy B shows a negative cost here, indicating fills were better than the period’s VWAP. |

This analysis demonstrates the quantitative benefit of the hybrid strategy. By routing a significant portion of the order to anonymous venues, Strategy B dramatically reduced the market impact cost. The signaling effect of the large order was suppressed, resulting in a much lower overall transaction cost. The data from such reports, aggregated over thousands of trades, is used to calibrate the parameters of the execution algorithms and the SOR.

## Predictive Scenario Analysis

To understand the operational reality, consider a case study. A portfolio manager at a quantitative hedge fund, “Alpha Prime,” needs to liquidate a 2 million share position in a mid-cap tech stock, “Innovate Corp,” currently trading around $52.50. The decision is based on their proprietary model indicating a short-term price decline.

This is a highly informed order; information leakage is the paramount concern. The head trader, Maria, is tasked with the execution.

Innovate Corp has an ADV of 10 million shares, so this order represents 20% of a typical day’s volume. A naive execution would be catastrophic, broadcasting her intent to the entire market and causing the price to plummet before she could offload a significant portion of her position. Maria’s execution console gives her a view across multiple venues ▴ a primary lit exchange (LITEX), two major anonymous CLOBs (ANON-A and ANON-B), and a dark pool aggregator (DARK-P).

Maria’s pre-trade analysis shows ample liquidity on LITEX, but the book is thin below the best bid. A large market order would walk the book down several price levels. ANON-A is showing consistent, small-sized interest, suggesting HFT liquidity provision.

ANON-B has larger, lumpier displayed sizes, hinting at institutional flow. DARK-P offers potential for large block crosses at the midpoint, but fills are sporadic.

Maria’s playbook for an informed order of this size calls for a “Stealth” algorithm. She parameterizes it as follows:
– Participation Rate ▴ Target no more than 15% of the traded volume per minute.
– Venue Allocation ▴ 60% to anonymous venues (split between ANON-A and ANON-B), 30% to DARK-P, and only 10% to the lit market (LITEX), primarily for price discovery probing.
– Order Type ▴ Use limit orders priced passively, just inside the opposite quote, to avoid crossing the spread and creating an aggressive signal. The algorithm will automatically cancel and re-price the orders as the market moves.

The execution begins at 10:00 AM. The Stealth algorithm starts by placing small “ping” orders across the venues. The fills from LITEX are immediate but cause a 1-cent dip in the bid each time. The fills on ANON-A are also fast and small.

After the first 15 minutes, she has sold 150,000 shares at an average price of $52.48. Her TCA monitor flashes a warning ▴ a “Toxicity Alert” on ANON-A. Her algorithm has detected a pattern where, immediately after one of her sell orders is filled, a new wave of sell orders appears on the lit market, pushing the price down. Someone on ANON-A is detecting her flow and trading ahead of it on LITEX.

Maria immediately adjusts the algorithm’s parameters, reducing the allocation to ANON-A to zero. She increases the passive [limit order](https://prime.greeks.live/area/limit-order/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) size on ANON-B, hoping to engage with another large institution that might be accumulating a position. At 10:30 AM, she gets a large fill in DARK-P ▴ a 200,000 share block crosses at the midpoint price of $52.44. This is a significant success, as it executed a large chunk of the order with zero market impact.

The process continues throughout the day. Maria constantly monitors the execution, watching the market’s reaction to her fills. She occasionally sends a small, aggressive order to the lit market to keep other algorithms guessing about her true intent. By 3:45 PM, she has liquidated the entire 2 million share position.

Her final TCA report shows an average sale price of $52.31. The arrival price was $52.50. Her total implementation shortfall is 19 cents per share, or $380,000. While a significant cost, her post-trade analysis estimates that a naive, lit-market-only execution would have resulted in an average price below $52.00, costing over $1 million. The strategic use of anonymous and dark venues, coupled with active, in-flight management, preserved over $600,000 in alpha for the fund.

## System Integration and Technological Architecture

The execution strategies described above are only possible with a sophisticated and deeply integrated technological architecture. The components of this system must communicate with high speed and precision.

## How Do Trading Systems Connect to Anonymous Venues?

The connection between an institutional trading desk and the various market centers is typically handled via the Financial Information eXchange (FIX) protocol. FIX is the industry standard language for communicating trade-related messages. To interact with an anonymous CLOB, the firm’s Execution Management System (EMS) must be configured to send the correct FIX messages.

- **NewOrderSingle (Tag 35=D)** ▴ This is the fundamental message for placing an order. To specify an anonymous venue, the ExDestination (Tag 100) field would be populated with the code for that specific exchange (e.g. ‘ANON-A’). Some venues might require a specific value in the ExecInst (Tag 18) field to indicate the order should be treated anonymously.

- **Order Slicing and Pegging** ▴ The EMS or the algorithm itself is responsible for creating pegged orders. For example, a PegInstruction (Tag 211) can be used to peg an order’s price to the midpoint or the best bid, ensuring the order remains passive. The EMS sends a continuous stream of OrderCancelReplaceRequest (Tag 35=G) messages to update the order’s price as the market moves.

- **Market Data Feeds** ▴ The trading system must subscribe to the direct market data feeds from each venue. For an anonymous CLOB, this feed provides the price and aggregate size at each level of the book. The speed and reliability of this data are critical for the algorithms to make informed decisions. The system must be able to process millions of messages per second.

The firm’s Order Management System (OMS) sits at a higher level, holding the parent order and tracking its overall progress. The EMS is the low-latency engine that works the child orders in the market. The seamless integration of the OMS, the algorithm engine, the SOR, and the FIX connectivity layer is the technological bedrock of modern institutional execution. Anonymity is a feature of the destination venues, and the firm’s internal architecture must be flexible enough to leverage this feature as part of a coherent, data-driven execution strategy.

## Reflection

The integration of anonymity into market architecture represents a permanent shift in the landscape of institutional trading. The knowledge gained about its effects on price discovery and liquidity is a critical input, a single parameter in a much larger equation. The truly resilient operational framework is one that views the entire market as a complex, interconnected system. The protocols for anonymity, the mechanics of RFQ systems, the latency of data feeds, and the logic of execution algorithms are all components of a single machine designed for one purpose ▴ the efficient translation of investment ideas into executed positions.

Consider your own operational framework. Is it a collection of disparate tools and strategies, or is it a coherent, integrated system? How does the data from your post-trade analysis feed back into the logic of your pre-trade decisions? Viewing the challenge through this systemic lens reveals that the debate over any single market feature, like anonymity, is secondary.

The primary objective is the construction of a superior operational intelligence layer, a system that not only understands the function of each component but also masters their strategic interplay. The ultimate edge is found in the quality of this architecture.

                "@type": "Answer",
                "text": "From the perspective of a liquidity provider or market maker, anonymity changes the calculus of placing limit orders. In a transparent market, a market maker might adjust their quotes based on which firm is seeking liquidity. They might offer a tighter spread to a client with whom they have a positive trading history and a wider spread to a firm known for aggressive, informed trading. Anonymity removes this ability. All incoming market orders must be treated as if they could be from an informed trader. This uncertainty can lead to market makers widening their spreads to compensate for the increased risk of adverse selection. However, academic studies and market events, like the switch to anonymity on the Australian Stock Exchange, have shown that anonymity can also empower institutional investors to post more aggressive, informative limit orders themselves, effectively competing with traditional market makers and contributing to narrower spreads at the top of book. This creates a dynamic tension: the risk of the unknown informed taker versus the benefit of the unknown informed maker."
