What is "Breakdown"?

A breakdown is a breakout to the downside.

Price trades sideways for a while, but it is unable to garner the strength to move higher. When this happens, it signals buyer weakness.

A breakdown happens when there is a breakout downward through support.

The buyers who used to be at this level are gone, but there is still selling pressure.

The price that breaks downwards through a support level is expected to continue to fall.

This is considered a sell signal, significantly if the volume is also increasing.

If the price has fallen significantly since the break, a better price can be achieved by waiting for a reaction back.

Please note that price in an uptrend often triggers false sell signals on breakdowns through support.
