Document rollover time, timezone, daylight-saving handling, and whether partial Sunday bars are merged, removed, or retained.

Daily close is a data choice
DESK 13A Daily EURUSD bar may close at New York rollover, midnight UTC, or another server boundary. That choice changes candle bodies, pattern labels, moving averages, and the number of Sunday fragments. Record the feed and daily cutoff before treating D1 patterns as portable rules.
Daily OHLC cannot identify whether a stop or target was reached first, and it cannot model the spread available at a specific intraday entry. Define next-open, stop-order, and gap handling precisely. Use H4 or finer data only to resolve predeclared sequence questions, never to redesign losing entries.
Document rollover time, timezone, daylight-saving handling, and whether partial Sunday bars are merged, removed, or retained.
State how orders fill when Monday or event prices cross an entry or stop. A requested price is not guaranteed by Daily data.
Multi-day trades can incur financing and triple-swap conventions. Model the intended venue or label holding cost as excluded.
The larger the candle, the more execution history it compresses into four numbers.
A Daily candle may close at New York rollover, midnight UTC, or another server boundary. That decision changes candle bodies, moving averages, pattern names, and whether a short Sunday bar exists, so the source and cutoff belong in the rule sheet.
D1 strategies produce fewer observations and often hold through rollover, weekends, and macro events. Measure opportunity count and effective independence; a handful of trades spanning one trend cannot establish robustness.
| Measurement | How to define it | Why it matters |
|---|---|---|
| Calendar construction | Cutoff time, timezone, DST treatment, Sunday-bar policy | Defines the exact D1 series under test |
| Gap execution | Requested price, first executable price, gap slippage | Stops favourable fills at unavailable prices |
| Carry cost | Swap or financing convention and holding nights | Converts gross multi-day return into a comparable net result |
| Regime concentration | Trades and P&L by year, volatility, and direction | Shows whether one macro trend dominates the sample |
Daily OHLC proves only the bar range. If both entry and exit levels fall inside it, use a predeclared lower-timeframe resolution rule without redesigning the setup after seeing the path.
