Understanding alternative trading systems (ATS)

Alternative trading systems (ATS) are critical components of modern financial markets, offering a platform for matching large buy and sell orders. These systems play a pivotal role in enhancing liquidity and facilitating efficient trading. In this comprehensive guide, we will explore the world of ATS, its definition, key features, regulatory framework, and criticisms.

What is an alternative trading system (ATS)?

An alternative trading system (ATS) is a trading venue that differs from traditional exchanges in terms of regulations and operations. ATS platforms are designed to match large buy and sell orders among their subscribers. The most widely used type of ATS in the United States is Electronic Communication Networks (ECNs), which are computerized systems that automatically match buy and sell orders for securities in the market.

Features of ATS

ATS platforms are characterized by several key features:
  • Regulatory differences: Unlike traditional exchanges, ATS are not as highly regulated. They do not set strict rules governing the conduct of subscribers.
  • Various names: ATS go by different names in various regions. In Europe, they are known as Multilateral Trading Facilities.
  • Liquidity access: ATS are essential in providing alternative means to access liquidity in the financial markets.
  • Institutional use: Institutional investors often use ATS to find counterparties for transactions, especially for large block trades.

Role of ATS in liquidity

ATS platforms account for a significant portion of the liquidity found in publicly traded securities worldwide. They enable efficient matching of buyers and sellers, contributing to the smooth functioning of financial markets. In Europe, ATS are referred to as Multilateral Trading Facilities (MTFs), and they have become integral to the trading landscape.

Pros and cons of ATS

Weigh the risks and benefits
Here is a list of the benefits and drawbacks to consider.
Pros
  • Efficient matching: ATS enable efficient matching of large buy and sell orders, enhancing liquidity.
  • Privacy: ATS transactions do not appear on national exchange order books, providing privacy for institutional investors.
  • Reduced market impact: Using ATS for large trades can reduce their impact on the price of an equity.
Cons
  • Less regulation: ATS face fewer regulations, which can lead to infractions and concerns about fair trading practices.
  • Dark pools: Some ATS, known as dark pools, lack transparency and are criticized for providing unfair advantages in the market.

Dark pools

Dark pools are a specific type of ATS used by institutional investors, primarily investment banks, to execute large orders away from traditional stock market exchanges. These transactions are often “dark” because they are not disclosed to the public. Dark pools have received criticism for their lack of transparency and their potential to provide unfair advantages to certain players in the stock market, especially when combined with high-frequency trading (HFT).

Regulation of alternative trading systems

Regulation ATS, established by the U.S. Securities and Exchange Commission (SEC), sets the regulatory framework for ATS. To operate as an ATS, certain requirements must be met:
  • Broker-dealer registration: An ATS must register as a broker-dealer to facilitate trading operations.
  • Initial reporting: Before commencing operations, an ATS must file an initial operation report with the SEC.
  • Ongoing reporting: ATS platforms are required to file amendments to Form ATS to inform the SEC of any operational changes or closures.
  • Transparency enhancements: Recent amendments to Regulation ATS aim to increase transparency, including public disclosures of potential conflicts of interest and safeguards for subscribers’ trading information.

ATS in practice

One example of ATS in practice is the utilization of dark pools by large institutional investors. Let’s take a closer look at how dark pools function:
Large institutional investors, such as hedge funds or pension funds, often handle substantial volumes of securities. When they need to execute a significant buy or sell order, they may use an ATS, specifically a dark pool, to prevent other investors from front-running or taking advantage of their intentions. In this scenario, the goal is to minimize market impact and maintain anonymity.
Dark pools operate as private exchanges, executing orders away from the central stock market. Most of the liquidity in dark pools is generated by block trades conducted by institutional investors, primarily investment banks. These transactions remain mostly undisclosed to the public, which is why they are referred to as “dark.”

Regulatory evolution

Over the years, the regulation of ATS has evolved to address concerns about transparency and fair trading practices. The financial industry and regulatory bodies have recognized the need to strike a balance between facilitating liquidity and ensuring a level playing field for all market participants.
One notable development is the amendment of SEC Regulation ATS in 2018. These amendments aimed to enhance “operational transparency” for ATS platforms. Under the new rules, ATS are required to provide detailed public disclosures to inform the general public about potential conflicts of interest and risks related to information leakage.
ATS platforms must also establish written safeguards and procedures to protect subscribers’ trading information. This shift towards greater transparency and accountability is crucial in ensuring that ATS continue to play a positive role in the financial markets.

The future of ATS

As financial markets and trading technologies continue to evolve, the role of ATS is expected to expand. Market participants will likely see further developments in terms of regulatory oversight and transparency requirements for these trading venues. ATS will continue to be a key element in the world of finance, serving as a vital platform for matching large buy and sell orders while adapting to the changing landscape.

Conclusion

Alternative trading systems (ATS) are vital components of the global financial markets, providing a platform for large buy and sell orders. While they offer advantages such as efficient matching and privacy, they are not as highly regulated as traditional exchanges. Understanding the role of ATS and their impact on trading strategies is essential for market participants. As regulation evolves, ATS platforms aim to strike a balance between liquidity facilitation and fair trading practices, ensuring a level playing field for all participants.
