Comparison
Bull Flag vs Falling Wedge
Both are bullish and both can drift downwards, which is why they are easy to mix up. A bull flag has parallel lines and must follow a sharp rally. A falling wedge has converging lines, can form after a long decline or as a pullback in an uptrend, and shows selling pressure fading.
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.
Falling Wedge
bullish bias
A falling wedge has both boundaries sloping downward, with the upper line falling faster than the lower one. Price keeps making lower lows, but each drop loses momentum, and a break above the upper line is the bullish trigger.
Side by side
| Aspect | Bull Flag | Falling Wedge |
|---|---|---|
| Lines | Parallel | Converging |
| Move before it | A sharp rally (the flagpole) | A decline or a pullback in an uptrend |
| Size | Small and brief relative to the flagpole | Often larger and longer |
| Target | Flagpole length from the breakout | Commonly the start of the wedge |
How to tell them apart on a chart
- Measure the gap between the lines. Constant means a flag; shrinking means a wedge.
- No flagpole means it is not a flag.
- Both confirm on a close above the upper line.
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.
Falling Wedge: confirmation and invalidation
Confirms: A close above the upper trendline.
Invalidated: A decisive close below the lower trendline.
Frequently asked questions
Is a falling wedge a bull flag?
Not quite. A falling wedge inside an uptrend plays a similar role, a pause before continuation, but its converging lines make it a different pattern.
Do both need volume to fall during the pattern?
Falling volume during the pause is often seen in both, but it is supporting evidence rather than a requirement.
