Session boundary
Store UTC and derive Europe/London and Tokyo labels with correct DST. Temporary seasonal overlap shifts must remain in the record.

A cross carries two regional clocks
FIELD 31EURJPY spans European and Japanese policy calendars, while its hourly liquidity shifts across Tokyo, London, and their transition. Define these windows historically and test one unchanged rule across them before claiming a session advantage.
Cross rates can inherit movement from both component legs, but EURJPY has its own spread and executable quote. Use direct instrument data, pair-specific costs, equal account risk, and predeclared event tags. Do not reconstruct fills from EURUSD and USDJPY mid prices.
Store UTC and derive Europe/London and Tokyo labels with correct DST. Temporary seasonal overlap shifts must remain in the record.
Choose ECB, euro-area, BOJ, and Japanese event categories before results. Report overlapping event windows separately.
Use EURJPY bid-ask or a disclosed cost model. Algebraic cross prices describe value, not necessarily available fills.
A regional story is useful context only after the clock and executable price are fixed.
EURJPY is algebraically related to EURUSD and USDJPY, yet tradable cross quotes include their own spread and timing. Synthetic reconstruction should be labelled and synchronized; direct execution results should use direct quotes when possible.
Tokyo and European participation, ECB and BOJ information, and global risk conditions can change the distribution. Use fixed session and event definitions without assigning a story after the result.
| Measurement | How to define it | Why it matters |
|---|---|---|
| Cross quote | Direct or synthetic source, timestamp, bid/ask, precision | Defines the executable instrument |
| Pip value | JPY quote precision and account-currency conversion | Keeps risk accurate as price changes |
| Dual-session clock | Tokyo and European local times converted historically | Prevents DST misclassification |
| Policy tail | ECB/BOJ event costs, gaps and excursions | Shows behaviour outside ordinary ranges |
Do not infer a direct cross fill from two mid-price leg candles. Synthetic bid/ask construction and timestamps must be consistent if direct EURJPY quotes are unavailable.
Minimum evidence label: publish the rule version, instrument and feed, timezone, dates, opportunity count, quote and cost model, unresolved-trade policy, holdout status, and uncertainty with the result.
