How do liquidity pools work?

Automated market makers (AMM) have changed this game. As no direct counterparty is needed to execute trades, traders can get in and out of positions on token pairs that likely would be highly illiquid on order book exchanges.

When you’re executing a trade on an AMM, you don’t have a counterparty in the traditional sense. Instead, you’re executing the trade against the liquidity in the liquidity pool. For the buyer to buy, there doesn’t need to be a seller at that particular moment, only sufficient liquidity in the pool.
