When you look at a liquidity pool, you're checking how much capital is locked in there—that's your liquidity number. More liquidity usually means bigger trades can happen with less price slippage, so you won't get feather-ruffled by tiny orders moving the price wildly. Volume tells you how much trading actually happened in that pool over a time period, say 24 hours. High volume means the pool is actively used; low volume can mean it's a ghost town where your trade might sit waiting for a match. The fee is what liquidity providers earn—typically 0.01%, 0.05%, 0.25%, or 1% depending on the pool. Lower fees attract traders, but higher fees compensate LPs for riskier pairs. Check the fee tier and ask: does the volume justify it, or am I looking at a dead pool? Liquidity depth, trading activity, and fee alignment together tell you if a pool is healthy or a trap.
