When a breakdown occurs, the level where price breaks below support often turns into resistance on the next pullback. This happens because traders who bought near the old support and got trapped now try to exit at breakeven when price comes back up, creating selling pressure at the same level. At the same time, fresh sellers see this retest as a low-risk selling opportunity, reinforcing supply. As a result, the breakdown point acts as a resistance zone, confirming a change in market polarity from support to resistance and signaling that the trend remains weak unless price decisively moves back above it.
