Flags and pennants are short-term continuation patterns that form after strong price moves. They represent brief consolidations before the trend continues in the original direction.
Understanding Flags and Pennants
Key Characteristics
Both Patterns:
- Form after sharp move (flagpole)
- Brief consolidation
- Continue in original direction
- Short-term patterns
Difference
Flag:
- Rectangular consolidation
- Parallel boundaries
Pennant:
- Triangular consolidation
- Converging boundaries
Bull Flag Pattern

Trading Bull Flag

Target:
- Height of flagpole projected from breakout
Bear Flag Pattern
Structure

- Strong downward move (flagpole)
- Upward or sideways consolidation (flag)
- Parallel trend lines
- Breakdown continues downtrend
Formation

- Above flag high
- Or above flagpole start
Target:
- Height of flagpole projected from breakdown
Bull Pennant Pattern
Structure
Components:
- Strong upward move (flagpole)
- Triangular consolidation
- Converging trend lines
- Breakout continues uptrend
Difference from Bull Flag
Pennant:
- Triangle shaped
- Lines converge
- Often tighter pattern
Trading Bull Pennant
Same Principles:
- Entry on breakout
- Stop below pattern
- Target = flagpole height
Bear Pennant Pattern
Structure
Components:
- Strong downward move (flagpole)
- Triangular consolidation
- Converging trend lines
- Breakdown continues downtrend
Trading Bear Pennant
Same Principles:
- Entry on breakdown
- Stop above pattern
- Target = flagpole height
Flagpole Requirements
What Makes a Flagpole
Characteristics:
- Sharp, impulsive move
- Strong momentum
- Clear directional thrust
- Significant distance
Weak Flagpoles
Problems:
- Gradual, grinding moves
- Multiple legs
- Overlapping candles
- Doesn't qualify
Flag/Pennant Proportions
Ideal Proportions
Guidelines:
- Flag retraces less than half of the flagpole, often about a third
- Not too deep
- Not too long in time
Too Deep
Problem:
- More than 50% retracement
- May not be flag
- Different pattern
Too Long
Problem:
- Extended consolidation
- Loses momentum
- Pattern may fail
Volume Characteristics
During Flagpole
Volume:
- High volume
- Strong conviction
- Impulsive buying/selling
During Flag
Volume:
- Decreasing volume
- Less interest
- Consolidation phase
At Breakout
Volume:
- Volume should increase
- Confirms breakout
- Shows renewed interest
Measuring Targets
Height Method
Process:
- Measure flagpole height
- From start to end of pole
- Project from breakout point
Example - Bull Flag
Setup:
- Flagpole: $40 to $50 (height $10)
- Flag forms $48-$50
- Breakout at $50
- Target: $60 ($50 + $10)
Conservative Target
Alternative:
- Use 75% of flagpole
- More realistic
- Higher probability
Pattern Quality
High-Quality Flags
Characteristics:
- Clear flagpole
- Tight consolidation
- Low volume in flag
- Volume on breakout
Low-Quality Flags
Characteristics:
- Weak flagpole
- Deep or long flag
- Messy consolidation
- No volume confirmation
Common Mistakes
Forcing Patterns
Problem: Seeing flags everywhere
Solution: Require clear flagpole
Trading Counter-Trend
Problem: Expecting bull flag in downtrend
Solution: Trade with larger trend
Too Tight Stops
Problem: Stop inside flag
Solution: Stop below/above flag boundary
No Confirmation
Problem: Entering before breakout
Solution: Wait for confirmed break
Flag Pattern Checklist
Before Entry
- [ ] Clear flagpole exists
- [ ] Flag is proper proportion
- [ ] Volume decreased in flag
- [ ] Breakout confirmed
- [ ] Volume on breakout
- [ ] Stop properly placed
- [ ] Target calculated
Flags vs Rectangles
Difference
Flag:
- Counter-trend slope
- Short duration
- After sharp move
Rectangle:
- Sideways only
- Can be longer
- May not have flagpole
Key Takeaways
- Flags and pennants are continuation patterns
- Form after strong moves (flagpole)
- Brief consolidation before continuation
- Flags have parallel lines
- Pennants have converging lines
- Volume decreases in pattern
- Volume increases on break
- Target = flagpole height projected
