Order-book wall events from the 1-minute footprint of a symbol, built on the consolidated book and trade tape of Binance, Bybit, OKX and Hyperliquid. Answers: "Did a large resting order get absorbed on BTC in the last hour?", "Were bid walls pulled before this drop?", "How thin was the book this hour?". A wall = a resting price row far larger than the book's typical row (above median + 5 MAD of row sizes). kind=absorbed: trades hit the wall for at least 5% of its peak size, it still held at least 85% of that peak at the minute's close, and price did not break through it. kind=pulled: the wall fell below half of its peak while trades covered less than 30% of the drop, it did not refill within 2 seconds, and price had come within reach of it (cancelled, not filled). Scope: only price rows that traded in that minute and lie within the nearest 60 rows per side of mid are examined, so distant or untouched walls are not reported. wall_side: bid = resting buy orders, ask = resting sell orders. Per event: t = minute open, epoch ms; price = USD, lower edge of a bucket-wide row; peak_usd = largest resting size seen in the minute; executed_usd = volume traded against the wall; close_usd = resting size at the minute's close (whole dollars). At most 4 events of each kind are kept per minute, the largest peaks. thin_minutes = minutes whose resting depth near mid (within 25 bps, capped at the nearest 60 rows per side) was below the 20th percentile of the previous 2 hours, per side (bid, ask, both); classified = minutes of the window classified so far (the newest 2-3 minutes are still pending). Window: from/to as RFC3339, YYYY-MM-DD or epoch ms; default the last hour; at most 24 h per call, longer is an error, not a clamp. kinds = absorbed and/or pulled (default both); min_usd filters by peak_usd; limit 1..=150 (default 50) keeps the NEWEST events, counts cover the whole window and truncated=true says the list was cut. coverage.archive_from is when recording began; the archive only grows forward, so a window before it is honestly empty. Descriptive: an event states what the book did, not what price will do. Read-only.
