Comparison
Bull Flag vs Bear Flag
They are the same pattern pointing opposite ways. A bull flag is a sharp rally followed by a small pause that drifts down, with a break up expected. A bear flag is a sharp drop followed by a small pause that drifts up, with a break down expected.
Bull Flag
bullish bias
A bull flag forms when a sharp rally (the pole) is followed by a short, controlled pullback in a small downward-sloping channel (the flag). It suggests the market is pausing rather than reversing.
Bear Flag
bearish bias
A bear flag forms when a sharp drop (the pole) is followed by a short, controlled bounce in a small upward-sloping channel (the flag). It suggests a pause before the decline may continue.
Side by side
| Aspect | Bull Flag | Bear Flag |
|---|---|---|
| Flagpole | A sharp rally | A sharp drop |
| Pause drifts | Down or sideways | Up or sideways |
| Confirmation | A close above the upper flag line | A close below the lower flag line |
| Invalidation | A close below the flag's low | A close above the flag's high |
How to tell them apart on a chart
- The direction of the flagpole decides it.
- The pause usually leans against the flagpole: down in a bull flag, up in a bear flag.
- In both, the flag should be small relative to the flagpole.
Bull Flag: confirmation and invalidation
Confirms: A close above the flag's upper line.
Invalidated: A close below the flag's lower line, or a retracement that eats most of the pole.
Bear Flag: confirmation and invalidation
Confirms: A close below the flag's lower line.
Invalidated: A close above the flag's upper line, or a bounce that recovers most of the pole.
Frequently asked questions
Are bear flags as common as bull flags?
They are common in downtrends. Falls are often sharper than rises, so bear flags can form and resolve faster.
Do flags work on all timeframes?
The shape appears on every timeframe. Lower timeframes produce more of them, and more failures.
