Completed-session volume and underlying-equivalent liquidity
“Last complete” uses the most recent completed calendar session shared by both rows when available; otherwise each row's latest completed date is shown. The 5D and 30D options unlock only when both listings have a full completed window. All averages and the historical chart use the exchange session close to exclude partial intraday volume from the comparison.

Historical matching
How point-in-time parity is built
- 1Each security close is pulled at the interval associated with the selected timeframe.
- 2JPY or EUR prices use the nearest available historical FX bar from the same range and interval. Current FX is used only if that historical FX observation is missing.
- 3Prices are converted into USD per japanese common share using each security ratio.
- 4Each foreign observation is paired with the preceding available japanese observation, then premium/discount is calculated from their normalized values.
Important limitation: market and FX timestamps may not align. Historical parity is indicative, not a synchronized or executable arbitrage series.
Refresh behavior
How and when each section updates
There is no timer-based polling. All visitors share one server-side cache, and concurrent visitors reuse cached data instead of making separate Yahoo requests.
Company overview
Page load + return after 5m
Loads when the page opens or reloads, then checks once when you return to the tab after at least five minutes. Market cap itself is cached for five minutes.
Relative value matrix
Page load + return after 5m
Security prices and current FX refresh together on page load or a qualifying return, keeping the premium or discount within one snapshot cycle.
Historical parity
Page load + timeframe change
Loads when the page opens and reloads only when you select a different timeframe. Returning to the tab does not interrupt the chart.
Trading volume
Page load + return after 5m
Updates with the shared snapshot. The table disables 5D or 30D windows until both listings have enough completed history, while the historical bar chart aligns the last 7 completed sessions. Active-session volume is excluded using the exchange session close.
