Launched the Guides section

Margin Trading Outstanding (Daily) API released: daily delivery with published date and value fields

• The Margin Trading Outstanding (Daily) API (formerly Margin Trading Outstandings), announced on August 24, 2026, is now available with the updated specification. Data delivery has changed from weekly to daily; data for the previous business day is available on each business day.
  • Daily data is available from September 25, 2026. Earlier data remains weekly and is dated as of the last business day of each week.

Release of the Valuation Indicators API

• The Valuation Indicators API, which delivers daily valuation indicators calculated from financial statement disclosures and share prices, is now available. It can be used on all plans.
  • Eight indicators are provided: EPS, FwdEPS, BPS, ROE, FwdROE, PER, FwdPER and PBR. Actual figures are based on trailing twelve months (TTM) net income, and forward figures are based on the company's forecast of net income for the current fiscal year.
  • Market capitalization (MktCap, in millions of JPY) is also recorded. It is calculated as the share price multiplied by the share count excluding treasury shares, so its value may not match market capitalization in the Daily Stock Prices (OHLC) API, which uses a share count that includes treasury shares.
• File download (CSV download / Bulk API) is also supported for the Light plan and above.

[Advance Notice] Market capitalization (MktCap) will be removed from the Daily Stock Prices (OHLC) API

• Market capitalization in the Valuation Indicators API is calculated using a share count that excludes treasury shares.
• Accordingly, market capitalization (MktCap) in the response of the Daily Stock Prices (OHLC) API, which is calculated with a share count that includes treasury shares, is scheduled to be removed. We will announce the removal date once it has been decided.
• Market capitalization is provided by the Valuation Indicators API, so please consider switching your reference. Note that the two APIs define the share count differently, so the values may not match.
