What is a breakout in trading?
In one line: A breakout is when price moves through a support or resistance level and stays beyond it, instead of turning back.
A simple example
A stock turned down near $25.00 three times last month. That area is resistance — a ceiling.
Today a candle pushes up and closes at $25.60, with its body fully above the ceiling. That's a breakout. The ceiling that held three times has given way.
Often, the old ceiling then acts like a floor. Price may come back down to about $25.00, hold, and move on. Many traders wait for that retest instead of buying the first push.
The body-close test
In our method, only a candle body closing past the level counts. A thin line (a wick) poking through and snapping back doesn't.

Why so strict? Because the poke-and-snap-back is exactly what a fakeout looks like while it's happening. Waiting for the close costs a little price, but it filters out many false starts. It won't filter them all.
Why it matters
Breakouts are where a market often changes gear. A range that went nowhere for weeks can start a new trend after one. That's why so many traders watch the same levels — and why the move through them can be fast.
A common mistake
Buying the very first tick through the level. Price touches $25.01, excitement kicks in, and the order goes in before the candle has even closed. If the candle then closes back below $25.00, the "breakout" was never real.
Before you trade a breakout, ask: where is my stop loss if this fails? If the answer is "far away," the trade gets smaller. Check it with the risk-reward calculator.

Questions
How do you confirm a breakout?
Wait for a candle body to close beyond the level. Some traders also look for higher volume or a retest that holds. None of these make it certain.
Do breakouts work on all timeframes?
The idea is the same on every chart, but a break on a daily chart usually matters more than one on a 1-minute chart.
What happens after a failed breakout?
Price often moves back into the old range, sometimes fast, because traders who bought the break get out.
