Reading the files

One file per asset per UTC day. The 5hz rows are the index about 5 times a second for BTC, ETH, SOL, XRP and DOGE (once a second for the rest); the 1hz rows add Kalshi's 60-second averages.
close_avg_60s is the average over the last minute before a quarter-hour close.
Join to Kalshi data on ts_recv: every dataset shares the same recorder clock.

A Kalshi crypto market settles on a CF Benchmarks index at its close. Having the index on the same clock as the books shows exactly what the settlement price was doing while the market traded.
