Alternative Trading System (ATS)

What is an Alternative Trading System (ATS)?

An Alternative Trading System (ATS) is a trading system that provides an alternative to the traditional exchange trading platforms for securities. Unlike traditional exchanges, ATSs operate with fewer regulatory requirements which allow them to offer various advantages, including lower trading fees, improved liquidity, and specialized trading capabilities tailored to various financial instruments.

Key Characteristics of ATS:

Electronic Trading: Most ATSs provide an electronic platform for trading, facilitating quick and efficient transactions.
Lower Costs: Due to less stringent regulations, ATSs often have lower operational costs, resulting in reduced fees for traders.
Block Trading: ATSs are preferred venues for trading large volumes of securities or block trades that may have a significant market impact if executed on a traditional exchange.
Anonymity: Many ATSs offer greater privacy, allowing investors to trade anonymously.
Liquidity Improvement: By providing additional venues for trading, ATSs contribute to increased market liquidity.
