JPX Market Innovation & Research, Inc. will begin offering 1-minute stock price data and futures and options OHLC data through J-Quants Pro, and will newly expand the daily delivery of margin trading balances by issue.
The service will begin offering 1-minute stock price OHLC data, along with trading volume and trading value, for TSE-listed stocks. The data provides a time series detailed enough to reproduce opening and closing movements, reactions immediately after earnings announcements, and intraday liquidity imbalances that are difficult to capture with daily data, making it easy to incorporate into analytical platforms. Stocks listed exclusively on regional exchanges are excluded.
Daily price information will be provided for futures and options traded on the Osaka Exchange and Tokyo Commodity Exchange. The data will include session-specific OHLC, trading volume, open interest, settlement prices, contract months and SQ dates, among other items, enabling the construction of continuous series using the front-month flag. Data recorded when margin is triggered in emergencies can also be identified.
Daily delivery of margin trading balances by issue will begin. Daily data will be provided for TSE-listed stocks, broken down by issue, long and short positions, and general and exchange-regulated margin transactions, supporting timely monitoring of supply-and-demand changes. Weekly data will continue to be provided as well.
An early contract discount campaign will be offered. For contracts for daily margin trading balances by issue signed by the end of December 2026, the usage fee through March 2027 will be discounted by 75%.
