What are Technical Indicators?


Technical indicators are mathematical calculations based on the price, volume, or open interest of a security or currency pair. These indicators are used to analyze and interpret market data, identify trends, and make informed trading decisions. They help traders to forecast future price movements and identify potential buy and sell signals.

Types of Technical Indicators

Technical indicators can be broadly categorized into the following types:

  1. Trend Indicators:
    • Moving Averages (MA): Smooth out price data to identify the direction of the trend.
      • Example: A 50-day MA on a EUR/USD chart helps determine the overall trend. If the price is above the MA, it indicates an uptrend, and below indicates a downtrend.
    • Moving Average Convergence Divergence (MACD): Measures the difference between two moving averages to identify changes in momentum.
      • Example: A bullish signal is generated when the MACD line crosses above the signal line on a GBP/USD chart.
  1. Momentum Indicators:
    • Relative Strength Index (RSI): Measures the speed and change of price movements to identify overbought or oversold conditions.
      • Example: An RSI above 70 on an S&P 500 index chart suggests overbought conditions, while an RSI below 30 suggests oversold conditions.
    • Stochastic Oscillator: Compares a security’s closing price to its price range over a given period to predict price reversals.
      • Example: On a USD/JPY chart, a buy signal is generated when the %K line crosses above the %D line at the 20 level.

  1. Volatility Indicators:
    • Bollinger Bands: Consist of a middle band (a simple moving average) and two outer bands (standard deviations from the middle band) to measure price volatility.
      • Example: On an Apple stock chart, if the price touches the upper Bollinger Band, it indicates the stock might be overbought.
    • Average True Range (ATR): Measures market volatility by calculating the average range between the high and low prices over a specific period.
      • Example: A high ATR value on a crude oil futures chart suggests significant volatility.
  1. Volume Indicators:
    • On-Balance Volume (OBV): Uses volume flow to predict changes in stock price.
      • Example: An increasing OBV on a Tesla stock chart indicates that volume is increasing during price rises, suggesting a bullish trend.
    • Volume Weighted Average Price (VWAP): The average price a security has traded at throughout the day, based on both volume and price.
      • Example: On an intraday Microsoft stock chart, VWAP is used as a benchmark to evaluate whether the current price is fair.

Application of Technical Indicators

Technical indicators are employed to:

  • Identify Trends: Help traders determine whether the market is in an uptrend, downtrend, or ranging.
    • Example: Using moving averages to identify the trend direction in a EUR/USD chart.
  • Generate Buy and Sell Signals: Provide entry and exit points for trades.
    • Example: A buy signal is generated when the RSI crosses below 30 and then rises above it on a GBP/JPY chart.
  • Measure Market Volatility: Assess the level of price fluctuations to gauge risk and set appropriate stop-loss levels.
    • Example: A high ATR on a NASDAQ index chart suggests increased market volatility and potential for large price swings.
  • Confirm Patterns: Validate chart patterns such as head and shoulders, double tops, and bottoms.
    • Example: Confirming a breakout pattern with an increase in volume using OBV on a Bitcoin chart.


Technical indicators are essential tools for traders and analysts, providing insights into market trends, momentum, volatility, and volume. By incorporating these indicators into their trading strategies, traders can make more informed decisions and improve their chances of success in the financial markets.
