"Dark pools, also known as dark liquidity or dark trading, are private, off-exchange trading venues where financial assets such as stocks, bonds, and other securities are bought and sold."
Introduction
Dark pools, also known as dark liquidity or dark trading, are private, off-exchange trading venues where financial assets such as stocks, bonds, and other securities are bought and sold. Unlike traditional stock exchanges where trading activities are visible to the public, dark pools offer a level of anonymity and opacity, as the transactions are not displayed on public order books or readily accessible to the broader market participants.
Key characteristics of dark pools include:
Confidentiality: Dark pools operate as private trading platforms, and their order books are not visible to the general public. Only participants within the dark pool have access to the details of the orders.
Limited Pre-Trade Transparency: Unlike traditional exchanges, dark pools do not display bid and ask prices or the size of orders. This lack of pre-trade transparency can shield large institutional trades from the impact of price movements and help prevent adverse price slippage.
Reduced Market Impact: Dark pools are often used by institutional investors and large traders who seek to execute significant buy or sell orders without causing significant price swings in the market. By keeping their trades hidden from the broader market, they can minimize the market impact of their transactions.
Lower Trading Costs: Dark pools can offer cost advantages, especially for large institutional investors, as they can avoid the fees and costs associated with trading on public exchanges. This can lead to reduced trading costs, making it an attractive option for some participants.
Algorithmic Trading: Many dark pools employ sophisticated algorithmic trading strategies to match orders efficiently. These algorithms can help identify suitable counterparties and execute trades based on predefined criteria, improving trade execution efficiency.
Regulatory Oversight: While dark pools provide confidentiality, they are subject to regulatory oversight to ensure fair and transparent trading practices. Regulators monitor these private trading venues to prevent market abuse, insider trading, and other potential manipulative activities.

Conclusion
Despite their benefits, dark pools have faced criticism and scrutiny. One concern is that the lack of transparency can lead to information asymmetry, disadvantaging retail investors who do not have access to these private venues. Additionally, there have been instances of regulatory investigations into potential manipulative practices in some dark pools.
It's important to note that the term "dark pools" can also be used more broadly to refer to any private trading venue, not just for traditional financial assets.
