10Y how low weekly, tick by tick.
Kalshi series KX10YRDIRLW: order book and trades, 2026-10-02 → 2026-10-23.

The order-book and trade history of Kalshi's 10Y how low weekly series (a new event every week): 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.

What a KX10YRDIRLW day contains

Four parquet files per day, every market of the series in each. Sizes are this series' own averages over its 22 days on disk.

Top of book (every change)kalshi_l1

Best 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.

~121 kB per KX10YRDIRLW day
Order book, 25 levels, every changekalshi_l2

The 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.

~560 kB per KX10YRDIRLW day

Every trade: YES and NO price, size in contracts, the taker's side, block-trade flag, trade id.

~17 kB per KX10YRDIRLW day
Kalshi ticker (~1 s)kalshi_ticker

Kalshi'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.

Coverage notes for KX10YRDIRLW

  • First day on disk: 2026-10-02. The series' first book appeared then. New days are added daily.
  • Trades before 2026-09-27. Kalshi's historical API has no tick-level order book, so earlier KX10YRDIRLW trades are in the whole-exchange trades history (from 2021-06-30, one file a day): filter market_ticker to this series' markets, which start with KX10YRDIRLW-.
  • Every bundle ships a README with the schemas and, per day, how often the rebuilt book matched the exchange's own snapshots, for your exact range.
