A high or low records the furthest value reached during the period. Using that extreme makes a boundary crossing visible as soon as the value trades beyond the level.
Closing value
A close is the final value for the chosen bar interval. Requiring a close beyond the boundary is a stricter definition because temporary excursions that reverse before the close do not qualify under that rule.
Timeframe changes the answer
A move can close beyond a level on a five-minute chart while remaining only a wick on a daily chart. That is not a contradiction; the sampling interval is different.
State the rule before evaluating examples
If you decide after seeing the outcome whether a wick or close “counts”, the definition becomes outcome-dependent. Educational analysis is clearer when the rule is chosen first and applied consistently.
Keep the distinction clear: a chart label describes geometry or past observations. It is not, by itself, a forecast, probability estimate or instruction to buy or sell.
