Hyperliquid Outcomes

Outcome OHLCV

PREVIEW

Returns OHLCV candles for one or more outcome legs over the requested interval. Provide either coin (full Hyperliquid coin identifier, e.g. #1730) or outcome_id (UInt64); both accept CSV for batched grid views. With outcome_id, the side selector resolves to side_index 0 (yes, default), 1 (no), or returns both (both).

Trade-side fields (buy_volume, sell_volume) carry the directional split: buy_volume counts taker buys of this leg, sell_volume counts taker sells. Composition events (SPLIT_OUTCOME, MERGE_OUTCOME, MERGE_QUESTION, NEGATE_OUTCOME) and SETTLEMENT payouts are excluded from candles by design; query them via /v1/hyperliquid/outcomes/trades for the raw stream.

When multiple legs are requested, each timestamp bucket is paginated as a unit — the response contains every requested leg's candle for the most recent limit distinct timestamps.

Every row embeds the compact outcome leg context (outcome_id, outcome_name, question_id, question_name, status, settle_fraction, coin, side_index, side_label). For full outcome metadata call /v1/hyperliquid/outcomes?outcome_id=....
