Bull & Bear Flags
Overview
Bull and bear flags are continuation patterns consisting of a sharp price move (the flagpole) followed by a brief, counter-trend consolidation channel (the flag). Bull flags slope downward after an upward pole; bear flags slope upward after a downward pole. These patterns represent a pause in strong momentum before the trend resumes, and they are among the most commonly traded continuation setups.
Key Concepts
Flagpole: a strong, near-vertical price move on high volume. Flag: a parallel channel sloping against the trend direction. Volume contracts during the flag formation and expands on the breakout. Duration: the flag typically lasts 1-4 weeks on daily charts. Measured-move target equals the length of the flagpole added to the breakout point.
Entry Signals
Enter on a breakout from the flag in the direction of the flagpole with volume confirmation. Aggressive entry near the lower boundary of a bull flag or upper boundary of a bear flag. The flag should retrace no more than 38.2-50% of the flagpole. Momentum indicators should remain in bullish or bearish territory during the flag consolidation.
Exit Signals
Primary target equals the flagpole length projected from the breakout point. Place stops below the flag's low (bull flag) or above the flag's high (bear flag). Trail stops using the flag's trendline once the breakout confirms. Exit if the flag retraces beyond 61.8% of the pole, as this weakens the pattern.

Pro Tips
The strongest flags form after impulsive, high-volume moves that break through significant levels. A flag that trades sideways rather than slightly against the trend shows even greater underlying strength. Volume contraction during the flag is essential — without it, the pattern may evolve into a reversal.

Ascending & Descending Triangles
Ascending triangles form when price creates a horizontal resistance line at the top and a rising support trendline at the bottom, indicating buyers are becoming more aggressive. Descending triangles feature a horizontal support floor with a declining resistance trendline, suggesting sellers are gaining control. Both patterns are typically continuation patterns that resolve in the direction of the prevailing trend with a measured move target equal to the triangle's height.
Rounding Bottom
The rounding bottom (also known as a saucer pattern) is a long-term bullish reversal formation characterised by a gradual, U-shaped transition from a downtrend to an uptrend. The pattern reflects a slow shift in sentiment from bearish to neutral to bullish, typically forming over weeks or months. A breakout above the pattern's resistance (the left rim level) confirms the reversal.
Inverse Cup & Handle
The inverse cup and handle is a bearish continuation or reversal pattern that mirrors the bullish cup and handle formation. It consists of a rounded top (the inverted cup) followed by a brief upward consolidation (the handle). The pattern indicates that buying attempts fail to sustain higher prices, and the handle's upward drift represents a final weak rally before sellers take control, breaking price below the handle's support.
Broadening & Expanding Patterns
Broadening patterns, also called megaphone or expanding patterns, form when price creates progressively higher highs and lower lows, diverging rather than converging. These patterns reflect increasing volatility and disagreement between buyers and sellers, often appearing during periods of uncertainty or at major market turning points. Broadening patterns are among the most challenging formations to trade because they lack the contracting structure of typical chart patterns.
