A breach and a confirmed event are different observations
An intraday high beyond resistance proves only that transactions occurred above it. A completed daily close above the same boundary supplies a different observation. Analysts may require a closing-price margin or several closes, but these filters trade earlier recognition for additional delay. No filter eliminates failure.
Define the return condition as carefully as the initial breach. For example, a close back inside the old range during the next two sessions could invalidate a particular breakout hypothesis. Another method might use a different window. Comparing their results requires retaining each original rule.
A 100-dollar ceiling and three possible closes
Assume resistance ends at 100 dollars and the test requires a completed close above 100.50, a 0.5% margin. A high of 101.20 followed by a 99.80 close does not pass. A later close at 100.80 does pass. If the following session closes at 99.60, the predefined two-session return rule records a failed breakout. The later return does not erase the fact that the earlier confirmation occurred.
Confirmation is conditional, not a guarantee
A strong news gap can skip the boundary and leave little opportunity near the assumed price. Thin activity, a wide bid–ask spread and a volatile close can create misleading excursions. A successful historical filter may also reflect the particular sample rather than a durable advantage. Record failures and ambiguous cases alongside attractive examples.
Compare the same candles with one fixed rule
Choose a completed range on an available daily, weekly or monthly chart. Freeze its boundaries, state whether extremes or closes govern the test, and examine the next completed candles in order. Describe each stage separately: inside the range, first breach, confirmation, or return. This disciplined description is more informative than attaching a confident label after seeing the whole move.
