What it is
A DEX volume reading compares today's volume with the venue's recent run rate and weekly change, then surfaces the places where turnover is unusually heavy or cooling sharply.
Why it matters
Volume is not depth, but it is pressure. When a DEX suddenly turns over much more activity, users are paying the spread, routing trades, and testing the available liquidity. That can corroborate fees, chain movement, or a liquidity tide.
How we read it
We read DeFiLlama's free DEX overview, filter out tiny venues, and rank the outliers by today's volume adjusted for how far they are running from their own weekly pace. If the venue has a protocol page we link to it; otherwise we link back here so the source does not pretend to be more precise than it is.
What it cannot tell you
Volume can be wash-like, incentive-driven, arbitrage-heavy, or a one-day liquidation event. It does not say capital arrived, and it does not say price direction. We keep it out of the net-flow number for that reason.
