Risk conversion
For a non-JPY account, calculate pip value at the trade timestamp and round size to the venue increment. Store intended and rounded risk.

Separate yen mechanics from the setup
FIELD 15USDJPY pip value in account currency changes with price, so fixed lots do not represent fixed dollar risk across a long sample. Size each trade from stop distance, current conversion, and the intended lot increment before comparing years or volatility regimes.
Policy surprises and suspected or confirmed intervention windows can dominate hourly ranges and execution. Tag them from contemporaneous records, but do not infer intervention solely from a large candle. Report ordinary and event-tagged observations separately with the same strategy rules.
For a non-JPY account, calculate pip value at the trade timestamp and round size to the venue increment. Store intended and rounded risk.
Define Tokyo, London, and New York windows in UTC with DST applied where relevant. Japan itself does not use daylight saving.
Keep extreme hourly bars in the primary sample unless exclusion was declared. Also show capped and uncapped summaries to expose concentration.
A yen backtest can look stable in pips while its dollar risk quietly changes.
USDJPY is quoted with a different conventional pip decimal from many non-JPY pairs. Store raw prices and instrument specifications so pip distance, account-currency risk, and position size are calculated rather than inferred from display formatting.
Tokyo, London, and New York participation can create different H1 distributions. Use historical local clocks, and treat central-bank decisions or intervention-related periods as predeclared analysis groups with wider cost scenarios.
| Measurement | How to define it | Why it matters |
|---|---|---|
| Price precision | Quote digits, pip definition, lot and account conversion | Prevents tenfold sizing and reporting errors |
| Session bucket | Tokyo, London, New York, overlap, rollover | Tests whether a rule depends on a particular liquidity window |
| Tail movement | Adverse/favourable excursion quantiles and gaps | Captures risk hidden by average hourly range |
| Macro tag | Known-at-the-time rate, decision, and intervention-event fields | Stops future information entering the entry decision |
Historical inclusion of a famous intervention does not make it predictable. An event label may describe exposure only if the information was not known before the decision.
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.
