The flag and pennant patterns is a continuation pattern - one of the recurring shapes traders watch to time entries with a clear stop and target. Below is how to spot the clean version, trade it with defined risk, and prove it works before you rely on it.
What it looks like
Both patterns start with a strong, near-vertical move called the pole. A flag is a small rectangular consolidation that drifts slightly against the trend. A pennant is a tiny symmetrical triangle in the same spot. Either way, the consolidation is shallow and brief - a pause, not a reversal - and price usually breaks out to continue in the pole's direction.
These are among the cleaner continuation setups because the pole gives an obvious target: a strong move tends to be followed by another of similar size once the flag breaks.
The structure at a glance
How to trade it
Every version of this setup shares the same three decisions - a trigger to enter, a level that invalidates the idea, and a measured place to take profit:
Where most traders lose with this pattern: forcing it. A pattern that needs squinting to see is not there. Wait for the clean version, let price confirm the break or retest, and size the trade with the position size calculator so a failed pattern costs a fixed, small amount.
Backtest it before you trust it
This pattern is a starting hypothesis, not a signal. The only way to know whether it pays on your pairs is to replay real charts and trade it by hand across a large sample, then read the win rate, risk-reward, and expectancy it produces. Patterns that look obvious in a textbook often behave very differently across a hundred real trades.
Flags & Pennants FAQ
Are flags and pennants bullish or bearish?
They are continuation patterns, so they take the direction of the move that preceded them. A flag after a strong rally is bullish and breaks up; a flag after a sharp sell-off is bearish and breaks down. The consolidation is just a pause before the original trend resumes.
How do you set a target for a flag pattern?
Measure the length of the pole - the sharp move before the flag - and project that same distance from the point where price breaks out of the flag. Because flags form mid-move, this pole-based target assumes the second leg roughly matches the first, which often holds.
What is the difference between a flag and a pennant?
A flag is a small rectangular channel that usually slopes against the trend, while a pennant is a small symmetrical triangle that converges to a point. They form in the same place - after a strong pole - and are traded the same way, so the distinction is mostly cosmetic.
