Key Technical Indicators: RSI, MACD, and Moving Averages
Learn how to use the three most popular technical indicators — RSI, MACD, and Moving Averages — to find better entry and exit points.
Why Use Technical Indicators?
Technical indicators transform raw price and volume data into visual signals that help you identify trends, momentum, and potential reversal zones. They are tools — not crystal balls — and work best when combined with candlestick analysis and market context.
Moving Averages (MA)
A moving average smooths price action by calculating the average closing price over a set number of periods.
Simple Moving Average (SMA)
Equal weight to every period. The 200-day SMA is one of the most watched indicators in crypto — price above it is generally bullish.
Exponential Moving Average (EMA)
More weight to recent prices, so it reacts faster to price changes. Common pairs: 9 EMA / 21 EMA (short-term) and 50 EMA / 200 EMA (longer-term).
- Golden Cross: 50 MA crosses above 200 MA → strong bullish signal.
- Death Cross: 50 MA crosses below 200 MA → strong bearish signal.
- Price bouncing off a major MA (e.g. 200 EMA) = dynamic support/resistance.
Relative Strength Index (RSI)
RSI measures the speed and magnitude of recent price changes. It oscillates between 0 and 100.
- Above 70: Overbought — price may be due for a pullback.
- Below 30: Oversold — price may be due for a bounce.
- Standard setting: 14-period RSI.
Divergence is one of RSI's most powerful signals: if price makes a new high but RSI makes a lower high, momentum is weakening — a bearish divergence. The reverse is bullish.
MACD (Moving Average Convergence Divergence)
MACD shows the relationship between two EMAs and a signal line.
- MACD Line: 12 EMA minus 26 EMA
- Signal Line: 9 EMA of the MACD line
- Histogram: Distance between MACD and Signal line
Trading Signals
- Bullish crossover: MACD line crosses above signal line → potential upward momentum.
- Bearish crossover: MACD line crosses below signal line → potential downward momentum.
- Zero line cross: MACD crossing above 0 = overall bullish; below 0 = bearish.
Combining Indicators: A Simple Framework
- Use 200 EMA to determine the overall trend (long only above, short only below).
- Use RSI to find potential entry zones (buy near 30 in an uptrend).
- Use MACD crossover as a trigger to enter the trade.
Remember: indicators lag — they describe what has happened. Use them alongside price action and support/resistance for higher probability setups.
