About the data

The free plan does not provide data for the last 12 weeks. What happens to the stock price if a stock split or other event occurs during this period?

When a stock split occurs, the historical stock prices are adjusted retroactively from the effective date. Therefore, if a stock split occurs between 12 weeks ago and the present, the stock price prior to 12 weeks ago will also be adjusted for the split.

Is it possible to obtain data from regional exchanges and PTS? Do you have any future distribution plans?

Only data for stocks listed on the Tokyo Stock Exchange will be distributed. There are no plans to distribute data from regional exchanges or PTS.
