Hour boundary
Confirm each bar’s opening timestamp and whether the provider labels bars by open or close. A one-hour offset can change every named-session rule.

Hourly does not mean timezone-free
CHECK 14EURUSD H1 supplies enough observations for intraday research without the extreme cost sensitivity of M1, but the result still depends on session definitions, data source, event treatment, and order sequencing. Write those controls before ranking setups.
If a rule references “the London candle” or “New York open,” convert local market time with the historical DST calendar. Europe and the United States change clocks on different dates, temporarily shifting their overlap.
Confirm each bar’s opening timestamp and whether the provider labels bars by open or close. A one-hour offset can change every named-session rule.
Tag ECB, Federal Reserve, inflation, labour, and other chosen releases from a recorded calendar; keep event and ordinary observations separate.
When entry and exit levels share one H1 range, finer data or a conservative rule is required. OHLC alone cannot establish the path.
Session labels are data transformations; undocumented transformations are hidden degrees of freedom.
H1 can support both intraday and short swing rules, but feed alignment determines which sixty minutes form each candle. Record the first bar timestamp and the timezone before using London, Frankfurt, or New York labels.
EURUSD may quote tightly in ordinary conditions, yet spreads, slippage, and gaps can expand around releases and daily rollover. Use a cost series or scenario bands rather than one permanently low spread.
| Measurement | How to define it | Why it matters |
|---|---|---|
| Feed identity | Provider, timezone, quote side, missing-bar policy | Makes the hourly series and indicators reproducible |
| Session clock | Historical local-to-data conversion for every date | Prevents DST drift from moving a strategy between sessions |
| Event exposure | Predeclared release calendar and before/after windows | Separates planned event risk from hindsight narratives |
| Cost sensitivity | Base and stressed spread, commission, slippage | Tests whether net expectancy survives realistic execution |
A large candle count is not a large independent sample when trades overlap or cluster in one regime. Report opportunity-level observations and use block-aware uncertainty estimates.
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.
