What is Technical Analysis?
Technical Analysis is the study of past price movements and trading volume to predict future price direction. Unlike fundamental analysis (which looks at a company's financials), technical analysis focuses purely on charts, patterns, and indicators.The core principle is simple: price reflects everything. All known information — earnings, news, sentiment — is already priced into the stock. By studying how prices move, you can identify patterns that repeat.
The Three Most Important Indicators
1. Moving Averages (MA)
A Moving Average smooths out price data by creating a constantly updated average price. The two most common types are:
Simple Moving Average (SMA): Calculates the average closing price over a specified number of days. - 50-Day SMA: The "medium-term trend." If the stock price is above the 50-day SMA, the medium-term trend is bullish. - 200-Day SMA: The "long-term trend." This is the most watched moving average by institutional investors. A stock trading above its 200-day SMA is considered to be in a long-term uptrend. Golden Cross vs Death Cross: - Golden Cross: When the 50-day SMA crosses above the 200-day SMA, it signals a major bullish trend change. This occurred in Nifty in June 2020, preceding a massive rally. - Death Cross: When the 50-day SMA crosses below the 200-day SMA, it signals a potential bearish trend. This is a warning sign for investors.2. RSI (Relative Strength Index)
The RSI measures the speed and magnitude of recent price changes to evaluate whether a stock is "overbought" or "oversold." It oscillates between 0 and 100.
How to Read RSI: - RSI above 70: The stock is overbought — it may have risen too fast and could pull back. - RSI below 30: The stock is oversold — it may have fallen too far and could bounce. - RSI between 40-60: Neutral territory — no strong signal. Important Note: RSI above 70 doesn't mean "sell immediately." In strong uptrends, stocks can remain overbought for weeks. RSI is best used in combination with other indicators and support/resistance levels. RSI Divergence: When the stock price makes a new high but RSI makes a lower high, it's called a bearish divergence — a warning that the uptrend may be losing steam. The opposite (bullish divergence) occurs at market bottoms.3. MACD (Moving Average Convergence Divergence)
The MACD is a trend-following momentum indicator. It consists of three components:
- MACD Line: The difference between the 12-day and 26-day Exponential Moving Averages (EMA)
- Signal Line: A 9-day EMA of the MACD Line
- Histogram: The visual difference between the MACD and Signal lines
Combining Indicators: A Practical Framework
No single indicator is reliable on its own. Professional traders combine multiple signals:
Strong Buy Signal (All Indicators Align)
1. Stock price is above the 200-day SMA ✅ (long-term trend is up) 2. RSI bounces off the 40-50 zone ✅ (not overbought, still has room) 3. MACD crosses above the signal line ✅ (momentum is turning positive)Strong Sell/Caution Signal
1. Stock price drops below the 200-day SMA ❌ 2. RSI falls from the 70+ zone ❌ 3. MACD crosses below the signal line ❌Common Mistakes to Avoid
- Over-relying on a single indicator: RSI alone won't make you profitable. Combine it with trend analysis and volume.
- Ignoring the timeframe: A stock can be oversold on the daily chart but overbought on the weekly chart. Always check multiple timeframes.
- Using indicators in isolation from fundamentals: Technical analysis tells you when to buy, but fundamental analysis tells you what to buy. Use both.
- Backtesting bias: Just because a pattern "worked" historically doesn't guarantee future performance.
