Every Hyperliquid perpetual, ranked by how many times its own normal daily volume it is trading right now — 24-hour notional against a 30-day baseline. Relative volume, so a small market punching above its weight ranks alongside the majors.
Multiplier = live rolling 24-hour notional ÷ mean daily notional over the last 30 settled days. The tick on each bar marks 1.00× (perfectly normal); the bar fills to 6×. 24h Change is the change in volume — the live 24-hour notional against the most recent settled day — a like-for-like window, where the multiplier compares against the 30-day norm. The 7d Volume sparkline is each coin’s last 7 settled days, scaled to its own range (shape, not size). Markets listed under 7 days ago have no honest baseline and show “--”.
Relative volume, not raw volume.
Raw volume just tells you BTC is bigger than everything else — you knew that. The multiplier normalizes each market against its own history, so a mid-cap perp trading at 4× its usual daily notional outranks a major drifting along at 0.9×. That is the number worth scanning.
Volume is typically the earliest observable sign that something has changed. Liquidity shifts, funding dislocations and liquidation cascades all show up in traded notional before they resolve into a clean price trend — which is why a coin at several times normal volume is worth a look regardless of which way it is going.
Why both a mean and a median? One blow-off day inside the window drags the mean up and makes today look quiet against it. The median barely moves. When the two multipliers disagree sharply, that coin's recent history is lumpy — and the median is usually the more honest read.
The baseline covers the last 30 settled UTC days. Today's partial day is deliberately excluded: counting a half-finished day would drag every average down and inflate every multiplier on the board.
