Hello Support Team,
Regarding 8207.T, the daily price data retrieved via the API is incorrect.
In addition to missing open price data for 513 days, there are 7 days in 1993 where OHLC inconsistencies occur.
This issue is likely caused by a mismatch between JPX's data and the data held on your end (with a high probability that your data is incorrect).
Could you please investigate this issue?
Thank you.
