This is a Level-2 historical data archive for the entire Chinese A-share market, including ten-level market snapshots, order book messages, and trade records. The data comes from vendor historical exports and is saved in Parquet format by trading day. It covers A-shares, ETFs, bonds, repurchase agreements, and other non-stock instruments. The historical list spans from January 3, 2017, to August 31, 2026, totaling 2,346 trading days, with approximately 555.855 billion rows of messages, compressed to about 6.18 TB. Files are still being uploaded in batches. As of September 4, 2026, 794 trading days have complete sets of three files (snapshots, orders, trades), accounting for 33.8% of the listed dates. The data can be used for studying order book dynamics, order flow, and trade behavior. However, note that exchange attribution cannot rely solely on suffixes (e.g., .SH/.SZ); prices must be divided by 10,000 to convert to Chinese yuan; cancellation codes differ by exchange (Shanghai in order book, Shenzhen in trade records), and some historical data may have missing or incomplete messages. It is intended for academic and non-commercial research purposes, as detailed in the LICENSE.
