Flag and Pennant Patterns: A Pause Before the Trend Continues
Flags and pennants are short-term continuation patterns appearing after a sharp move. We explain the structure, the flagpole, the breakout point, and how to distinguish them from a reversal.
Price "catches its breath" in the middle of a strong trend
After a sharp, fast rise (or fall), price often pauses to move sideways or correct slightly before continuing. The two most common forms of this pause are the flag and pennant patterns — both continuation patterns, signaling the trend is likely to continue.
The flagpole — the initial sharp move
Both patterns begin with a "flagpole": a steep, strong move, usually on large volume. This is the "fuel" of the trend.
Distinguishing a flag from a pennant
After the flagpole comes the "pause," and this is where they differ:
- Flag: price corrects within a parallel channel sloped mildly against the trend — looking like a tilted rectangular flag.
- Pennant: price contracts into a small converging triangle — looking like a pennant. This is a small, short version of the triangle pattern.
Both show "temporary consolidation" — the winning side rests, the corrective force fading.
The breakout point and price target
- Breakout point: when price breaks out of the flag in the direction of the original trend — a continuation signal. This is a form of breakout.
- Price target: usually estimated by the flagpole length, projected from the breakout point — expecting the next move to be about as long as the first.
- Volume: contracts within the flag, then surges on the breakout — confirming the signal.
Characteristics and notes
- Short-term: flags and pennants usually form quickly (a few sessions to a few weeks). A pattern lasting too long loses its "continuation" character.
- A break against the trend = a warning: if price breaks against the trend direction, the pattern fails — it may become a reversal.
- Do not confuse with a reversal: a flag is a pause within a trend, different from the double top/bottom (reversal). The trend context decides.
- Always set a stop-loss: just outside the pattern, against false breakouts.
Conclusion
Flags and pennants are short-term continuation patterns appearing after a strong flagpole: a flag is a mildly sloped parallel channel, a pennant is a small converging triangle. A breakout in the trend direction with rising volume is a continuation signal, with the target measured by the flagpole length. Confirm with volume, distinguish from a reversal, and always set a stop-loss.
