Bear Flag Pattern
Mirror image of a bull flag. Sharp decline (pole) followed by an upward-sloping consolidation (flag). Breaks downward.
Trading rules at a glance
- Entry
- Short on close below the lower flag trendline.
- Stop Loss
- Above the highest point of the flag.
- Target
- Pole length projected downward from the breakdown.
How the Bear Flag forms
Pole: sharp vertical drop on heavy volume. Flag: narrow upward or sideways consolidation on declining volume. Completes on break below the lower flag trendline.
How to trade it
- Spot a strong impulsive decline with wide bearish candles.
- Wait for a tight, rising consolidation — deep retracements invalidate the flag.
- Short on close below the lower flag boundary.
- Project the pole distance downward from the breakdown for your target.
Common mistakes to avoid
- Trading flags that retrace more than 50% of the pole.
- Confusing normal corrections with bear flags.
- Entering too late after the breakdown.
Real-world example
S&P 500 formed multiple bear flags during the 2022 bear market, most notably during the August-September leg down when each countertrend rally resolved in lower lows.
Best timeframes
The Bear Flag works best on 15m, 1H, 4H charts. It can appear on lower timeframes but signal reliability drops significantly below the 1-hour chart.
