Liquidity Provider (LP)
A Liquidity Provider (LP) is a market participant that actively quotes both buy and sell prices for financial instruments, providing other market participants with the ability to execute trades readily. LPs play a crucial role in maintaining market efficiency by ensuring continuous price discovery and reducing trading friction.
Role in market structure
Liquidity Providers serve as essential intermediaries in financial markets by:
- Continuously posting two-sided quotes (bid and ask prices)
- Maintaining inventory to facilitate client trades
- Managing risk exposure across multiple assets
- Contributing to price discovery and market efficiency
Their presence helps reduce slippage and transaction costs for other market participants.
