This high-frequency dataset provides intraday minute-level candlestick information for a single security listed on either the Shanghai Stock Exchange or Shenzhen Stock Exchange, covering 1/3/5/15/30/60-minute granularities. Currently, the supported security categories include stocks, stock indices, and funds. The valid trading time windows for the minute-level data are: 09:30 to 11:30 in the morning, and 13:01 to 15:00 in the afternoon. The minute-level data follows the "first-open, last-close" backward aggregation rule: specifically, the time interval (9:31:00.000, 9:32:00.000] is assigned to the 9:32-minute dataset, while the 9:30-minute dataset includes all transactions executed prior to 09:30:00, i.e., the transactions from the pre-market call auction session.
