Frequently asked

Questions about this quote

What 6857.T historical data does TECHi show?

TECHi shows dated Advantest Corporation closing prices, with high, low, volume, dividend, and split columns whenever those values are available for the session.

How does TECHi calculate 6857.T returns and volatility?

Returns use the displayed closing prices. Realised volatility is calculated only when enough dated observations exist, using the annualised standard deviation of daily log returns.

How current is the 6857.T price history?

The 6857.T table runs through the most recent completed trading session. While the cash session is open, today's unfinished bar is shown separately and is left out of returns, volatility, and the daily table.

How much 6857.T history is included?

The table and summary use only the sessions delivered in the displayed series; TECHi does not infer older prices or fill missing dates.
