Tick-by-tick trades and order-book depth for every Kalshi “Challenger WTA” contract — 138 trading days as downloadable day bundles, €1 per day.
Per-day trade and turnover statistics exist from July 2026 onward; older days are archived without them.
A series-day bundle contains every Challenger WTA contract that traded on Kalshi on that UTC day — 4 contract files on the latest covered day. Each file carries the full raw feed: every trade print with price, size and side, plus Level-2 order-book updates, in the same zstd-compressed schema as our crypto venues. Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs February 2026 – August 2026 — 138 trading days, 10.9 GB compressed in total. A day typically holds 32 contract files (up to 96 on the busiest day, 415 MB). Pick individual days in the shop calendar for €1 each; delivery is an instant per-file download or one archive for the whole day.
