Technical Analysis: Chart Patterns and Indicators
Technical analysis is a method of evaluating securities by analyzing statistics generated by market activity, such as past prices and volume. Technical analysts use charts and other tools to identify patterns and trends that may indicate future price movements. This approach assumes that market psychology and historical price action can predict future market behavior.
Understanding Chart Patterns
Chart patterns are formations on price charts that technical analysts believe can predict future price movements. They are broadly categorized into continuation patterns (suggesting a trend will continue) and reversal patterns (suggesting a trend is about to change).
Continuation patterns suggest a pause before the existing trend resumes.
These patterns, like flags, pennants, and triangles, indicate a temporary consolidation in price before the prior trend continues. They are often seen as periods of rest for the market.
Continuation patterns are formations that suggest a temporary pause in an existing trend, after which the trend is expected to resume. Common continuation patterns include:
- Flags and Pennants: These are short-term patterns that appear after a sharp price move (the 'flagpole'). Flags are typically rectangular consolidations, while pennants are triangular consolidations. Both suggest a brief pause before the trend continues.
- Triangles: Ascending, descending, and symmetrical triangles can all act as continuation patterns. They represent a period of consolidation where price action narrows, often preceding a breakout in the direction of the prior trend.
- Rectangles: Also known as trading ranges, rectangles form when prices move sideways between support and resistance levels, indicating a pause before continuing the existing trend.
Reversal patterns signal a potential shift in market direction.
These patterns, such as head and shoulders, double tops/bottoms, and wedges, suggest that the current trend is losing momentum and a new trend may be emerging.
Reversal patterns are formations that suggest a trend is nearing its end and a new trend is likely to begin. These are critical for traders looking to enter positions at the beginning of a new trend or exit positions before a significant reversal. Key reversal patterns include:
- Head and Shoulders (and Inverse Head and Shoulders): A bearish reversal pattern formed by three peaks, with the middle peak (head) being the highest. An inverse head and shoulders is a bullish reversal pattern.
- Double Tops and Double Bottoms: These patterns form when a price fails to break through a resistance level (double top) or support level (double bottom) twice, suggesting a potential reversal.
- Wedges: Rising wedges in an uptrend can signal a bearish reversal, while falling wedges in a downtrend can signal a bullish reversal. They represent a contracting price range.
Key Technical Indicators
Technical indicators are mathematical calculations based on price and/or volume data that are used to forecast future price movements. They help traders confirm trends, identify potential turning points, and gauge market momentum.
Moving Averages (MAs) are one of the most fundamental technical indicators. They smooth out price data by creating a constantly updated average price. A simple moving average (SMA) calculates the average price over a specific period, while an exponential moving average (EMA) gives more weight to recent prices. Crossovers between different moving averages (e.g., a shorter-term MA crossing above a longer-term MA) are often interpreted as buy signals, and vice versa.

Oscillators help measure the speed and change of price movements.
Indicators like the Relative Strength Index (RSI) and Stochastic Oscillator help identify overbought or oversold conditions, suggesting potential price reversals.
Oscillators are a class of technical indicators that fluctuate within a defined range, typically between 0 and 100. They are used to identify overbought or oversold conditions in a security.
- Relative Strength Index (RSI): Measures the magnitude of recent price changes to evaluate overbought or oversold conditions. An RSI above 70 is generally considered overbought, while an RSI below 30 is considered oversold.
- Stochastic Oscillator: Compares a security's closing price to its price range over a given period. Like RSI, readings above 80 suggest overbought conditions, and readings below 20 suggest oversold conditions.
Volume indicators gauge trading activity and its impact on price.
Indicators like On-Balance Volume (OBV) and the Volume Rate of Change (VROC) help confirm trends and identify potential divergences.
Volume indicators analyze trading volume to provide insights into market sentiment and the strength of price trends.
- On-Balance Volume (OBV): A momentum indicator that relates volume to price change. It is used to predict future price movements based on volume flow. If prices are rising and OBV is also rising, it suggests strong buying pressure. If prices are falling and OBV is falling, it suggests strong selling pressure.
- Volume Rate of Change (VROC): Measures the change in volume over a specified period. It can help identify shifts in trading activity that might precede price changes.
Combining Patterns and Indicators
The most effective technical analysis often involves using multiple indicators and chart patterns in conjunction. This confluence of signals can provide stronger confirmation of potential trading opportunities. For example, a bullish reversal pattern like a double bottom, confirmed by an RSI moving out of oversold territory and increasing volume, might be considered a more robust buy signal.
Remember, technical analysis is not foolproof. It's a tool to increase the probability of successful trades, not a guarantee. Always consider risk management strategies.
