A breakdown is a downward price break through an identified support level, the bottom of a trading range, or a chart-pattern boundary. It is the downward form of a breakout and describes price behavior, not a failure of the blockchain or trading platform.
Losing a support area
Suppose buyers previously absorbed selling around 30, and price subsequently trades below that area at 28. Analysts may describe this as a breakdown of support near 30. The move can reflect aggressive selling, reduced buying interest, or both; the chart alone does not identify the cause.
Some traders require a candle close below support, while others consider intraperiod moves. The chosen timeframe, venue, and use of a zone rather than an exact line affect the interpretation. Higher trading volume can add context but does not make continued decline certain.
Failed breaks and retests
After a breakdown, price may return toward the former support, which traders watch as possible resistance. Such a retest is optional and does not guarantee another drop.
If price instead recovers the old range, the breakdown may prove false and trap short sellers. A confirmed candle close still cannot rule out recovery. Breaking support also does not establish an asset’s fair value or justify an unlimited downside forecast.
