Investing in the stock market can feel overwhelming, especially for beginners. With so much data to analyze, how do you know when to buy or sell a stock? Technical indicators are powerful tools that help investors interpret price movements and identify trends. In this guide, we’ll explore three essential indicators: RSI (Relative Strength Index), MACD (Moving Average Convergence Divergence), and Bollinger Bands.
These indicators are widely used by traders globally and are equally effective in analyzing stock markets. By mastering them, you’ll gain confidence in making data-driven trading decisions.
What Are Technical Indicators?
Technical indicators are mathematical calculations based on historical price and volume data. They serve two primary purposes:
- Predictive Analysis: Identifying potential future price movements.
- Descriptive Analysis: Gauging whether a stock is overbought, oversold, or trending.
Think of them as a compass guiding you through market volatility. Below, we break down three cornerstone indicators: RSI, MACD, and Bollinger Bands.
RSI (Relative Strength Index): The Momentum Gauge
What Is RSI?
The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of price changes. It ranges from 0 to 100 and helps identify:
- Overbought Conditions (RSI > 70): The asset may be overvalued.
- Oversold Conditions (RSI < 30): The asset may be undervalued.
How to Use RSI in Trading
- Overbought Signal: When RSI exceeds 70, consider selling or avoiding new buys.
- Oversold Signal: When RSI drops below 30, watch for buying opportunities.
Example: If TCS has an RSI of 75, it might be overbought, signaling a potential price correction. Conversely, an RSI of 25 suggests oversold conditions, possibly a good entry point.

MACD (Moving Average Convergence Divergence): The Trend Tracker
What Is MACD?
The MACD is a trend-following indicator that highlights relationships between moving averages. Its components:
- MACD Line: Difference between 12-day and 26-day EMAs.
- Signal Line: 9-day EMA of the MACD Line.
- Histogram: Visualizes the gap between the MACD and Signal lines.
Trading Signals from MACD
- Bullish Crossover: MACD line crosses above the Signal Line → Buy signal.
- Bearish Crossover: MACD line crosses below the Signal Line → Sell signal.
Example: For HDFC Bank, a bullish MACD crossover could indicate a buying opportunity, while a bearish crossover might suggest exiting the position.
Bollinger Bands: The Volatility Measurer
What Are Bollinger Bands?
This tool consists of:
- A 20-day SMA (middle band).
- Upper/Lower Bands: Set at ±2 standard deviations from the middle band.
How to Interpret Bollinger Bands
- Price Touching Upper Band: Potential overbought condition.
- Price Touching Lower Band: Potential oversold condition.
- Band Squeeze: Low volatility, often precedes a sharp price move.
Example: If Reliance Industries hits the lower band, it may signal a buying opportunity. Conversely, touching the upper band could indicate a sell chance.
Combining RSI, MACD, and Bollinger Bands
Using these indicators together enhances accuracy:
- RSI confirms overbought/oversold conditions.
- MACD validates trend direction.
- Bollinger Bands assess volatility.
Case Study: If Infosys shows:
- RSI < 30 (oversold),
- MACD bullish crossover,
- Price near lower Bollinger Band,
it’s a strong buy signal.
