Resistance zone at 24940-24950 tested twice and rejected. Support at 24905-24915 held twice. Eventually resistance breaks — watch the pullback to the broken level (role reversal) where old resistance becomes new support.
You already know what support and resistance are from Reading Charts — price floors where buyers step in, and ceilings where sellers step in, drawn as zones rather than exact lines. This lesson goes deeper: what happens AFTER a level breaks, how to trade the role reversal, and how volume confirms which levels actually matter.
