The order-book and trade history of Kalshi's NHL Ted Lindsay Winner series (new markets on an irregular schedule, one event per game, match or release): top of book on every change, the 25-level book on every change in YES terms, every trade with the taker's side, and Kalshi's own ticker, with exchange timestamps to the millisecond. Captured by us from Kalshi's websocket on two independent legs and checked against the exchange's own book snapshots.
Four parquet files per day, every market of the series in each. Sizes are this series' own averages over its 17 days on disk.
kalshi_l1Best YES bid and ask with sizes and the spread, one row whenever either changed, derived tick by tick from the rebuilt book: not Kalshi's conflated ticker.
kalshi_l2The whole ladder after every book event, in YES terms (the NO bids become the asks, at their sizes), 25 levels a side: wide columns bid_px_1 … ask_sz_25, plus the exchange's own hourly snapshots. Each row is self-contained, so you can start reading mid-day.
kalshi_tradesEvery trade: YES and NO price, size in contracts, the taker's side, block-trade flag, trade id.
kalshi_tickerKalshi's own ticker feed, about one update a second per market: last price, YES bid/ask with sizes, cumulative volume and open interest in contracts and dollars.
The 12 closing nearest to now, from Kalshi's daily market list. Each is a row key (market_ticker) in every table, captured from the day it opens until it settles.
