Tick-by-tick trades and order-book depth for every Kalshi “Champions League First Hal Winner” contract — 110 trading days as downloadable day bundles, €1 per day.
Trades and USD turnover summed over every contract of the series across 10 captured days to 2026-09-10, from the recorded tick data — the per-day averages divide by the captured days.

A series-day bundle contains every Champions League First Hal Winner contract that traded on Kalshi on that UTC day — 18 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.
