}Outcome probability history
Per bucket of one outcome market (Yes side): the last traded Yes price (trade_px, what Hyperliquid’s candle close and hyperdash.com plot; a No-book trade at px counts as 1 − px; a bucket without a trade carries the last trade before it, last_trade_time < the bucket start), the mark and mid (implied probability) and 24 h volume of the bucket’s last market snapshot (5-minute cadence), and open interest in shares ($1 face). Buckets with trades but no snapshot have null snapshot fields. limit buckets per page.
Pricing: base + per bucket. Scope: analytics:read.
