In fact read this (properly) and you might get it
Market Makers
A market maker is an individual participant or member firm of an exchange that buys and sells securities for its own account.
Market makers provide the market with liquidity and depth while profiting from the difference in the bid-ask spread.
Brokerage houses are the most common types of market makers, providing purchase and sale solutions for investors.
Market makers are compensated for the risk of holding assets because a security's value may decline between its purchase and sale to another buyer.
Dark Pools:
Dark pools are private asset exchanges designed to provide additional liquidity and anonymity for trading large blocks of securities away from the public eye.
Dark pools provide pricing and cost advantages to buy-side institutions such as mutual funds, and pension funds, which claim that these benefits ultimately accrue to the retail investors who invest in these funds.
However, dark pools’ lack of transparency makes them susceptible to conflicts of interest by their owners and predatory trading practices by HFT firms.
