The question
What was actually known when the condition was recorded?
- A temporary crossing can disappear before a bar closes.
- Waiting for completion changes timing and the available price.
- Confirmation does not remove uncertainty or guarantee a fill.
State the observation and its timing.
A price can cross a reference while a candle is still forming, then return before that interval ends. A completed candle beyond the same reference is a different observation. The diagram deliberately separates the two instead of treating the unfinished bar as final.
Define the reference, chart interval and condition before looking at later results. A completed observation can still fail, and another test might use a different condition; there is no universal confirmation rule supplied by this guide.
Completion and execution are separate.
Information available at a candle's completion is not necessarily available at its opening price. Notifications, spreads and order handling can introduce additional differences. A simulation that uses a completed candle to justify an earlier fill can create look-ahead bias.
Read the source time, website publication time and current alert state separately. A reported event or a finished bar does not prove a member received information in time or obtained a particular broker fill.
Keep uncertainty after the signal.
Additional conditions can reduce the number of candidates or change their entry distance without improving outcomes. Include failed confirmations and trading costs when evaluating a rule, rather than selecting clean-looking examples.
