Technical Analysis explained
- Technical Analysis Explained
Technical Analysis is a method of evaluating investments by analyzing past market data, primarily price and volume. Unlike Fundamental Analysis, which attempts to determine a security's intrinsic value, technical analysis focuses on *predicting* future price movements based on historical patterns and trends. It's a cornerstone of trading for many, especially short-term traders, but can also be used by longer-term investors to refine entry and exit points. This article will provide a comprehensive overview of technical analysis, geared towards beginners, covering its core principles, tools, and common strategies.
Core Principles of Technical Analysis
Technical analysis rests on three key assumptions:
- Market Discounts Everything: All known information about a security is already reflected in its price. This means trying to find "undervalued" stocks based on news isn't the focus; the price *is* the information.
- Prices Move in Trends: Prices don’t move randomly. They exhibit trends, which can be upward (bullish), downward (bearish), or sideways (ranging). Identifying and capitalizing on these trends is the primary goal. Understanding Trend Following is crucial.
- History Tends to Repeat Itself: Market participants often react to similar situations in similar ways. This creates recognizable patterns in price charts that can be used to predict future price movements. This is where concepts like Chart Patterns become important.
These assumptions aren't universally accepted, and criticisms exist (discussed later), but they form the basis of the technical analyst's approach.
Tools of the Trade
Technical analysts employ a variety of tools to interpret market data. These can be broadly categorized into:
- Charts: The visual representation of price data over time. Different chart types are used, each offering a unique perspective.
* Line Charts: The simplest form, connecting closing prices for each period. Good for identifying long-term trends. * Bar Charts: Show the open, high, low, and closing prices for each period. Provide more detail than line charts. * Candlestick Charts: A more visually rich type of bar chart, using "candles" to represent price movements. Popular for their ability to highlight potential reversal patterns. Understanding Candlestick Patterns is key. * Point and Figure Charts: Filter out minor price fluctuations, focusing on significant price changes. Useful for identifying support and resistance levels.
- Indicators: Mathematical calculations based on price and/or volume data, designed to generate trading signals or confirm trends. There are hundreds of indicators, each with its own strengths and weaknesses. We'll cover some common ones below.
- Trendlines: Lines drawn on a chart to connect a series of highs or lows, visually representing the direction of a trend. Breaking a trendline can signal a potential trend reversal.
- Support and Resistance Levels: Price levels where the price has historically found support (buying pressure) or resistance (selling pressure). These levels can act as potential entry or exit points.
- Volume: The number of shares or contracts traded during a given period. Volume can confirm trends – rising prices with increasing volume suggest a strong bullish trend.
- Fibonacci Retracements: Using Fibonacci ratios to identify potential support and resistance levels. Based on the Fibonacci sequence, these levels are often used in conjunction with other technical tools. Investopedia - Fibonacci Retracement
- Elliott Wave Theory: A complex theory that suggests prices move in specific patterns called "waves." Elliott Wave International
- Moving Averages: Smoothing price data over a specified period to identify trends and potential support/resistance. School of Pipsology - Moving Averages
Common Technical Indicators
Here’s a look at some of the most popular technical indicators:
- Moving Averages (MA): Calculated by averaging the price over a specific period (e.g., 50-day MA, 200-day MA). Help smooth out price fluctuations and identify the direction of the trend. Common types include Simple Moving Average (SMA) and Exponential Moving Average (EMA). CFI - Moving Average
- Relative Strength Index (RSI): An oscillator that measures the magnitude of recent price changes to evaluate overbought or oversold conditions. RSI values range from 0 to 100. Generally, an RSI above 70 suggests overbought conditions, while an RSI below 30 suggests oversold conditions. Investopedia - RSI
- Moving Average Convergence Divergence (MACD): A trend-following momentum indicator that shows the relationship between two moving averages of prices. Signals are generated when the MACD line crosses above or below the signal line. Fidelity - MACD
- Bollinger Bands: A volatility indicator consisting of a moving average and two bands plotted at standard deviations above and below the moving average. Prices tend to stay within the bands, and breakouts can signal potential trading opportunities. BabyPips - Bollinger Bands
- Stochastic Oscillator: Similar to RSI, it measures the momentum of the price. It compares the closing price to its price range over a given period. TradingView - Stochastic Oscillator
- Average True Range (ATR): Measures market volatility. Higher ATR values indicate higher volatility, while lower values indicate lower volatility.
- Volume Weighted Average Price (VWAP): Calculates the average price a security has traded at throughout the day, based on both price and volume.
It's important to note that no single indicator is foolproof. Technical analysts often use a combination of indicators to confirm signals and increase the probability of success. Indicator Combinations are a crucial aspect of a trading strategy.
Chart Patterns
Chart patterns are visually recognizable formations on a price chart that suggest potential future price movements. Some common chart patterns include:
- Head and Shoulders: A bearish reversal pattern that signals a potential downtrend.
- Inverse Head and Shoulders: A bullish reversal pattern that signals a potential uptrend.
- Double Top: A bearish reversal pattern.
- Double Bottom: A bullish reversal pattern.
- Triangles: Can be ascending, descending, or symmetrical, and can signal either continuation or reversal patterns.
- Flags and Pennants: Short-term continuation patterns.
- Cup and Handle: A bullish continuation pattern.

Trading Strategies Based on Technical Analysis
Many trading strategies are based on technical analysis. Here are a few examples:
- Trend Following: Identifying and trading in the direction of the prevailing trend. Requires identifying trendlines, moving averages, and other trend indicators. Investopedia - Trend Following
- Breakout Trading: Entering a trade when the price breaks above a resistance level or below a support level. Often used in conjunction with volume confirmation.
- Range Trading: Buying at support levels and selling at resistance levels in a sideways market.
- Swing Trading: Holding trades for a few days or weeks to profit from short-term price swings.
- Day Trading: Entering and exiting trades within the same day, relying heavily on short-term chart patterns and indicators. The Street - Day Trading
- Scalping: Making very short-term trades, often lasting only seconds or minutes, to profit from small price movements.
Each strategy has its own risk profile and requires a specific skill set. Risk Management is paramount in all trading strategies.
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: Many indicators are based on past price data and can lag behind current market movements.
- Self-Fulfilling Prophecy: If enough traders believe in a particular pattern or indicator, it can become a self-fulfilling prophecy, influencing price movements.
- Doesn’t Account for Fundamental Factors: Technical analysis ignores fundamental factors that can influence price, such as company earnings or economic news.
- Market Manipulation: Prices can be artificially manipulated, invalidating technical patterns.
Combining Technical and Fundamental Analysis
Many traders use a combination of technical and fundamental analysis to make informed trading decisions. Fundamental analysis can help identify potentially undervalued or overvalued securities, while technical analysis can help refine entry and exit points. This approach, known as Combined Analysis, can potentially improve trading performance.
