Not every chart pattern signals a reversal. Some mark a pause — a short breather before the existing trend picks up where it left off. Flags and pennants are the classic examples, and they're among the most recognisable continuation patterns in technical analysis.
Reversal vs continuation
Most chart patterns fall into two families. Reversal patterns signal a change of trend (think head and shoulders or double tops). Continuation patterns signal that the trend will likely resume after a brief consolidation. Flags and pennants belong firmly in the continuation camp — they're pauses, not turns.
What flags and pennants look like
Both form after a strong, near-vertical price move — the "flagpole" — and represent a short consolidation before the trend continues:
- Flag. A small, rectangular channel that slopes against the prior trend. After a sharp rally, the flag drifts slightly downward as the market catches its breath.
- Pennant. A small symmetrical triangle where the price range narrows to a point, with converging trendlines, before the breakout.
The difference is shape: a flag is a tilted rectangle, a pennant is a tiny converging triangle. Both do the same job — a brief consolidation inside an ongoing trend. (A pennant is essentially a miniature version of the triangle patterns covered separately.)
Trade the breakout, not the pause
The key rule with continuation patterns is patience: the pattern pays off on the breakout, when price exits the consolidation in the direction of the original trend. Trading inside the flag or pennant — before the break — means guessing. Waiting for the breakout means trading the actual signal.
Warning
A "continuation" pattern only continues if price breaks the right way. Patterns can fail — a flag can break against the trend. Wait for the breakout to confirm before acting.
How to trade them sensibly
Because flags and pennants form fast and break quickly, structure matters:
- Confirm the trend first. These patterns only make sense inside a clear existing trend.
- Wait for the breakout in the trend's direction before entering.
- Place a stop loss on the other side of the pattern, so a false breakout caps your risk.
- Beware low-liquidity breakouts, which are more prone to failing and reversing.
Risk
No pattern is guaranteed. Breakouts can be false, especially in choppy or thin markets. Always confirm the break and protect the trade with a stop loss.
