Use before acting on a Hyperliquid perpetual to see how its most profitable traders are positioned: how many wallets in a 200-wallet smart-money cohort are long vs short, long, short and net USD, the 24h change, concentration, leverage settings, share of open interest, and how that compares with the crowd (funding, 7-day move). Flags smart money positioned against a crowded move. Aggregates only, never wallet addresses. Signed. Not investment advice.
