Also known as: Bearish flag
A bear flag is a bearish continuation pattern made of a sharp, steep decline, the flagpole, followed by a brief, weak bounce inside a small channel that slopes slightly upward, the flag. A break below the bottom of the flag suggests the selling pressure is returning and the downtrend may continue.
It is the mirror image of the bull flag and is widely used in falling markets to time entries with a tight, well-defined risk.
What the pattern looks like
The flagpole is a fast drop, often on heavy volume and often triggered by bad news or a breakdown from support. Price then pauses and drifts higher in a narrow, roughly parallel channel as short sellers take profits and bargain hunters step in. The bounce lacks conviction, and when price breaks the lower boundary of the channel, the pattern completes.
The flag should look small, slow and orderly compared with the pole. A bounce that is as forceful as the drop is a different story.
How to identify it
- Flagpole. A steep decline over relatively few candles.
- Flag. A tight bounce that drifts up or sideways inside a parallel channel.
- Shallow retracement. The bounce recovers only a modest share of the drop.
- Short duration. The flag lasts noticeably less time than the pole took.
- Light volume. Volume tends to fall during the flag.
- Breakdown. A close below the flag’s lower line, ideally on a volume pickup.
How to trade it
Entry. The standard trigger is a close below the flag’s lower trendline. Some traders sell near the top of the flag on a bearish candle such as an evening star, accepting more risk of a failed pattern.
Stop. A typical stop sits above the flag’s highest high. Because flags are narrow, the risk is usually small relative to the pole.
Target (measured move). Measure the flagpole from top to bottom and subtract that distance from the breakdown point.
Worked example: a stock falls from $70 to $40 (a $30 pole), then bounces to $49 in a tight rising channel. It breaks below the flag at $45. The measured-move target is $45 − $30 = $15. That would be a deep move, and the full target is often not reached, so many traders cover part of the position at the pole’s low ($40) and trail a stop on the rest. With a stop above the flag high at $49.50, the risk is $4.50. Use the position size calculator to size the position and the risk/reward calculator to compare targets.
Confirmation: volume, RSI, sentiment
- Volume. Heavy volume on the drop, light volume on the bounce and a fresh pickup on the breakdown is the textbook profile.
- RSI. The RSI often reaches oversold readings during the pole, recovers modestly during the flag and turns down again at the breakdown. An RSI that stays capped below its midline during the bounce supports the bearish read.
- Sentiment. Bear flags often form while “relief” narratives circulate. If the crowd turns optimistic on a weak, low-volume bounce, that contrast is worth noting, though it is not a trigger.
Common mistakes
- No real pole. A gradual decline followed by a bounce is not a bear flag.
- Shorting too late. Selling at the bottom of the pole means a wide stop just before the bounce.
- Deep flags. A bounce that retraces much of the drop undermines the pattern.
- Ignoring the bigger trend. In a strong uptrend on a higher timeframe, a bear flag on a lower timeframe is more likely to fail.
- Overlooking short squeezes. Crowded short positions can produce sharp upside moves; respect the stop.
Pattern statistics caveat
Bear flags are popular for their tight risk, but they fail regularly, especially in choppy markets or around major news. Outcomes vary across markets and timeframes, and any precise success rate quoted online should be read with caution. Compare with the descending triangle and the rising wedge, which also tend to resolve lower.
