Explain the Difference between a Designated Market Maker and an Independent Liquidity Provider.
A designated market maker (DMM) has a formal, contractual obligation with an exchange to maintain a continuous, two-sided market (bid and ask) for a specific set of securities, often receiving exclusive privileges. An independent liquidity provider (LP) operates without such a formal contract, providing liquidity opportunistically based on their own trading strategies.
DMMs provide a baseline of required liquidity, while independent LPs supplement this to tighten spreads and further reduce slippage.
