13.4 Technical Analysis
13.4.1 Chart Patterns
Technical analysis involves studying past market data, primarily price and volume, to forecast future price movements. Among the tools and techniques in technical analysis, chart patterns are a fundamental component used by traders to identify opportunities and formulate strategy decisions related to buying, selling, or holding a security. This section will explore common chart patterns including head and shoulders, double tops, and triangles, emphasizing their structure and potential implications for price movements.
Common Chart Patterns
-
Head and Shoulders
- Formation: This pattern consists of three peaks; the middle peak (head) is the highest, with two lower peaks (shoulders) on either side.
- Types: There are two variations:
- Head and Shoulders Top: An indicator of a trend reversal from bullish to bearish. After the formation of this pattern, a price decline is anticipated.
- Head and Shoulders Bottom (Inverse Head and Shoulders): Often signals a trend reversal from bearish to bullish, where a price rise is expected following the pattern’s completion.
- Implications: Widely considered a strong indicator of reversal. The neckline, formed by connecting the lowest points of the two troughs for a top and the peaks of the two crests for a bottom, serves as a critical level. A breakout from this neckline confirms the pattern.

Double Tops and Bottoms
- Formation:
- Double Top: Characterized by two peaks at approximately the same price level, often indicative of an impending downward reversal.
- Double Bottom: Mirrors the double top but in reversal, with two troughs suggesting a potential upward reversal.
- Implications: These patterns imply a weakening of the prevailing trend. A break through the trough (for double tops) or peak (for double bottoms) confirms a reversal.

Triangles
- Types:
- Ascending Triangle: Features a flat top trendline and a rising bottom trendline, often a bullish pattern implying eventual breakout to the upside.
- Descending Triangle: Typically considered bearish, it has a descending top trendline and a flat bottom trendline, signaling potential breakdown to the downside.
- Symmetrical Triangle: Formed by a converging trendline liming lower highs and one marking higher lows; a breakout can occur in either direction.
- Implications: Triangles often precede continuation of the prevailing trend. The breakout direction indicates potential movement: upside for upward breakouts in ascending and symmetrical triangles, and downside for descending triangles or downward breakouts in symmetrical triangles.
