breakdown

When price falls through a floor it had been staying above.

The fuller meaning

A decisive close below support or a pattern's lower boundary, the downside version of a breakout. Traders look for a close rather than a wick, rising volume and follow-through; a breakdown that quickly reverses back above the level becomes a failed pattern.
