Use before opening, sizing or holding a Hyperliquid perpetual position to see where forced selling or buying would hit: known longs liquidating within 1 to 20% below the mark and shorts above it, the biggest clusters, and coverage of open interest, set against order-book depth, spread and slippage as cascade ratios. Flags long_cascade_risk, short_squeeze_risk, thin_book. From large accounts' public positions. Aggregates only. Signed. Not investment advice.
