Technical analysis principles
- Technical Analysis Principles
Technical analysis is a method of evaluating investments by analyzing past market data, primarily price and volume. It's based on the premise that historical trading activity and price patterns can be indicators of future price movements. Unlike fundamental analysis, which examines economic factors to determine an asset’s value, technical analysis focuses solely on the market data itself. This article provides a comprehensive introduction to the core principles of technical analysis, aimed at beginners.
Core Assumptions
Technical analysis rests on three primary assumptions:
- Market discounts everything. This means all known information about a security – including fundamental factors – is already reflected in its price. Therefore, analyzing fundamentals is unnecessary, as the price already incorporates them.
- Price moves in trends. Trends are the driving force in the market. Identifying and following these trends is key to successful trading. Trends aren’t random; they tend to persist for a period. Understanding trend types is crucial (see section below).
- History repeats itself. Patterns observed in the past are likely to reappear in the future. This is based on the idea that investor psychology doesn’t change drastically over time, leading to similar reactions to similar market conditions. This is the foundation of chart pattern recognition.
The Tools of Technical Analysis
Technical analysts use a variety of tools to interpret market data. These fall broadly into two categories:
- Charts and Chart Patterns: Visual representations of price movements over time are the cornerstone of technical analysis. Common chart types include:
*Line Charts: Simplest form, connecting closing prices over time. *Bar Charts: Display open, high, low, and closing prices for each period. *Candlestick Charts: Similar to bar charts but visually more appealing and provide more information about price action. Candlestick patterns are particularly significant. *Point and Figure Charts: Filter out minor price movements to focus on significant turning points.
Chart patterns are recognizable formations on price charts that suggest potential future price movements. Examples include: *Head and Shoulders: Reversal pattern indicating a potential trend change. [1] *Double Top/Bottom: Reversal patterns indicating potential trend changes. [2] *'Triangles (Ascending, Descending, Symmetrical): Continuation or reversal patterns depending on the breakout direction. [3] *Flags and Pennants: Short-term continuation patterns. [4]
- Technical Indicators: Mathematical calculations based on price and volume data designed to generate trading signals. Indicators are generally categorized as:
*Trend Following Indicators: Help identify the direction of the trend. *'Moving Averages (MA): Smooth out price data to identify the trend. ([5](https://www.investopedia.com/terms/m/movingaverage.asp)) Different types exist (Simple, Exponential, Weighted). *'Moving Average Convergence Divergence (MACD): Indicates the relationship between two moving averages. ([6](https://www.investopedia.com/terms/m/macd.asp)) *'Average Directional Index (ADX): Measures the strength of a trend. [7] *Momentum Indicators: Measure the speed of price changes. *'Relative Strength Index (RSI): Identifies overbought and oversold conditions. ([8](https://www.investopedia.com/terms/r/rsi.asp)) *Stochastic Oscillator: Compares a security’s closing price to its price range over a given period. [9] *'Commodity Channel Index (CCI): Identifies cyclical trends. [10] *Volume Indicators: Analyze trading volume to confirm price trends. *'On Balance Volume (OBV): Relates price and volume. ([11](https://www.investopedia.com/terms/o/obv.asp)) *'Accumulation/Distribution Line (A/D Line): Similar to OBV, focusing on where price closes within its range. [12] *Volatility Indicators: Measure the degree of price fluctuation. *Bollinger Bands: Plots bands around a moving average, indicating volatility. ([13](https://www.investopedia.com/terms/b/bollingerbands.asp)) *'Average True Range (ATR): Measures the average range of price fluctuations. [14]
Understanding Trends
Identifying the prevailing trend is fundamental to technical analysis. There are three main types of trends:
- Uptrend: Characterized by higher highs and higher lows. Prices are generally moving upwards. Buying is favored in an uptrend. [15]
- Downtrend: Characterized by lower highs and lower lows. Prices are generally moving downwards. Selling or shorting is favored in a downtrend. [16]
- 'Sideways Trend (Range-bound): Prices are fluctuating within a relatively narrow range, with no clear upward or downward direction. This indicates indecision in the market. [17]
Trendlines: Lines drawn on a chart connecting a series of highs or lows to visually represent the trend. Breaking a trendline can signal a potential trend reversal.
Support and Resistance
Support levels are price levels where buying pressure is strong enough to prevent the price from falling further. These are areas where demand exceeds supply.
Resistance levels are price levels where selling pressure is strong enough to prevent the price from rising further. These are areas where supply exceeds demand.
Prices tend to bounce off support and resistance levels. Breaking through these levels can signal a continuation of the trend. Support and resistance levels are not precise price points, but rather zones or areas. [18]
Fibonacci Retracements
Fibonacci retracements are horizontal lines that indicate potential support and resistance levels. They are based on the Fibonacci sequence, a mathematical sequence found in nature. Commonly used retracement levels are 23.6%, 38.2%, 50%, 61.8%, and 78.6%. Traders use these levels to identify potential entry and exit points. [19]
Japanese Candlesticks
Japanese candlesticks are a visually rich way to represent price movements. Each candlestick represents the price action for a specific period. The “body” of the candlestick represents the range between the open and closing price. The “wicks” or “shadows” represent the high and low prices. Different candlestick patterns can signal potential reversals, continuations, or indecision in the market. Doji, Hammer, and Engulfing patterns are a few examples. [20]
Volume Analysis
Volume refers to the number of shares or contracts traded during a specific period. Analyzing volume can confirm price trends and identify potential reversals.
- Increasing volume during a price trend usually confirms the trend's strength.
- Decreasing volume during a price trend may indicate a weakening trend.
- High volume during a breakout of a support or resistance level suggests a strong move.
- Divergence between price and volume can signal a potential reversal. For example, if the price is making new highs but volume is declining, it may suggest that the uptrend is losing momentum.
Combining Indicators & Risk Management
No single indicator or pattern is foolproof. Successful technical analysis involves combining multiple tools and indicators to confirm trading signals. For example, a trader might use a moving average crossover to identify a trend, an RSI to confirm overbought or oversold conditions, and volume analysis to confirm the strength of the trend.
Crucially, technical analysis *must* be combined with sound risk management practices. This includes:
- Setting stop-loss orders: To limit potential losses.
- Using appropriate position sizing: To avoid risking too much capital on a single trade.
- Diversifying your portfolio: To reduce overall risk.
- Understanding your risk tolerance: And trading accordingly.
Limitations of Technical Analysis
While powerful, technical analysis isn’t without its limitations:
- Subjectivity: Interpreting charts and indicators can be subjective, leading to different conclusions among analysts.
- False Signals: Indicators can generate false signals, leading to losing trades.
- Lagging Indicators: Some indicators are lagging, meaning they confirm a trend after it has already started.
- Market Efficiency: The efficient market hypothesis suggests that all available information is already reflected in prices, making technical analysis ineffective. However, behavioral finance suggests that market inefficiencies do exist and can be exploited.
- External Factors: Unexpected news events or geopolitical factors can override technical patterns.
