An Alternative Trading System (ATS) in the USA refers to a trading platform that is not a recognized public exchange but is nevertheless approved and regulated by the Securities and Exchange Commission (SEC). In many cases, ATSs are fully electronic, and buyers and sellers are matched anonymously. Transactions only become public after they are completed, which has raised concerns about the lack of information regarding trades and positions, potentially increasing the risk of market abuse. Similar trading systems exist worldwide, with the European equivalent known as the Multilateral Trading Facility (MTF).
Historical Context
The concept of ATS emerged in the late 20th century as financial markets sought more efficient and flexible trading solutions outside the traditional exchanges like the New York Stock Exchange (NYSE) and NASDAQ. The rise of technology and the internet fueled this development, leading to the creation of electronic communication networks (ECNs) and dark pools, which are sub-categories of ATSs.
Types of Alternative Trading Systems
Electronic Communication Networks (ECNs)
ECNs are a type of ATS that automatically matches buy and sell orders at specified prices. They are known for their transparency and efficiency in executing orders.
Dark Pools
Dark Pools are ATSs where trades are executed with little public disclosure, primarily to minimize market impact. They are popular among institutional investors who need to execute large orders without significantly affecting stock prices.
Crossing Networks
Crossing Networks match buy and sell orders without displaying quotes on public order books, allowing trades to happen at predetermined intervals or conditions.
