The hip4_hyperliquid.open_interest_hourly table provides hourly open interest and traded volume per Hyperliquid HIP-4 market. Grain: one row per (hour, market_id), with a row for every hour from the market’s first activity to its settlement. Open interest is a level at the end of the hour; volume is the flow within it. Open interest is built from the full token ledger (trades, splits, merges, negations and settlements) and excludes the venue’s settlement counterparty. It is counted per side. On standalone markets the Yes and No sides are equal. On event members they can diverge once No tokens are converted into Yes tokens of sibling outcomes. event_oi_contracts gives the collateral locked behind the whole event.
event_oi_contracts is repeated on every member row of an event. Summing it across members overstates event open interest. Take it once per event_id and hour.
Per-token prices are in hip4_hyperliquid.ohlcv_hourly.
