A breakout happens when price leaves a range or pattern it has been stuck in, crossing resistance to the upside or support to the downside (a breakdown). The idea is that the orders defending the level have been absorbed, so price can travel more freely. Breakouts are the trigger for many chart patterns, from the ascending triangle to the cup and handle.
How it works
Traders usually look for three things:
- A well-defined level. Several touches make it clear where the break is.
- A close beyond it. An intraday poke is not enough; the candle should close outside the level on the chosen timeframe.
- Participation. Volume noticeably above average, and often an expansion in volatility after a quiet, compressed period.
Two entry styles are common: entering on the breakout close, or waiting for a retest where the old resistance acts as support. Stops typically go back inside the range, because a return inside means the breakout failed. Measured-move targets often project the height of the range or pattern from the breakout point.
Example
A stock has traded between $30 and $34 for six weeks, with three tops at $34. On Monday it closes at $34.80 on volume 1.8 times its 20-day average. A trader buys at $34.80 with a stop-loss at $33.20, inside the old range, risking $1.60 per share. The range height is $4, so the measured-move target is $38, a potential reward of $3.20, for a risk/reward ratio of 1 : 2. If price closes back below $34 two days later, the setup has become a false breakout and the stop limits the damage.
Common mistakes
- Chasing extended moves. Buying far above the level leaves no room for a normal retest.
- Ignoring volume. Breakouts on thin volume fail more often.
- Stops too tight. A stop just above the level gets hit by the routine retest.
- Trading every break. Breakouts against the higher-timeframe trend are weaker.
