Stock Prices (Tick) (/equities/trades)

Overview

Tick-by-tick transaction data is provided in CSV format.
You can obtain detailed data such as price, volume, and timestamp for individual trades (executions).

This data is only available in CSV format and cannot be accessed via API.
To download CSV files, please use the List of Downloadable Files API and Get File Download URL API. You can also download from the Download page after signing in.

Attention

  • Coverage:
    • Coverage is limited to issues listed on the TSE. Issues that are not listed on the TSE (issues listed only on regional exchanges) and PTS data are not included. See also the FAQ "Is data from regional exchanges and PTS available?".
    • Delisted issues can also be retrieved by specifying dates or periods within their listing period, as long as they fall within the data storage period. See also the FAQ "Can I retrieve data for delisted stocks?".
    • Coverage is limited to executions in the auction market of the Tokyo Stock Exchange. Off-auction trades such as ToSTNeT trades are not included.
  • Missing values and absent records:
    • Only executions that were actually made are recorded. No record exists for time periods in which no execution was made.
  • Executions at the same time and the same price are aggregated into a single record. One record does not necessarily correspond to one execution.
  • Later corrections and cancellations are reflected by replacing the data and files for that date with the corrected content. Pre-correction data is not retained and no versioning is provided, so a pre-correction state cannot be reproduced afterwards.
  • The execution price (Price) and the execution volume (TradingVolume) are unadjusted values; no adjustment for stock splits, reverse splits, etc. is applied. For adjusted prices, see the Stock Prices (OHLC).
  • The data retention period is 2 years regardless of the base plan.
  • CSV files are provided as a single file covering all issues. Splitting by issue and downloading only specified issues are not supported.
  • We do not provide the date and time when each data item became available on J-Quants. For update frequency and approximate update times, see Update Timing of Provided Data.
  • Questions we have received about data specifications are also answered in the FAQ (Data & Specs).

Data correction policy

  • In this service, we may add or overwrite data due to data deficiencies or omissions. In such cases, the correction history is recorded on Data Correction History and Known issues, so please refer to it.
    Note: In these cases, neither the correction history nor pre-correction data is provided via the API, CSV, or other means.

Items Not Provided

  • Quotes, order book data, and orders/cancellations are not included (executions only).
  • No item indicating the trade direction (buy or sell execution) is provided.
  • Trading value is not provided as an item. It can be calculated from the execution price (Price) and the execution volume (TradingVolume).
  • No item indicating that an execution was made by auction (Itayose) is provided. It must be inferred from the execution time and other information.

Execution volume (shares)
When executions at the same time and the same price are aggregated into a single record, the total of those executions is stored.

TransactionIdstring

Transaction ID
Within the same issue (Code) and the same date (Date), the values of this field do not repeat, so a record can be uniquely identified by the combination of Date, Code, and this field. Within that scope, ascending order of this field also matches the order in which the executions occurred. To place multiple records that share the same Time in chronological order, sort by this field.
It cannot be used to compare records across different issues or across different dates.
