RSI Basics: Theory
What Is the RSI?
Developed by J. Wilder in the 1970s, the RSI is an oscillator that measures price momentum. By default, it calculates price changes over 14 periods (e.g., 14 days on daily charts). The formula compares average gains to average losses, plotted on a 0–100 scale.
How Does the RSI Work?
- Overbought (70+): Potential sell signal
- Oversold (30–): Potential buy opportunity
- Neutral Zone (30–70): Indicates market balance
Practical Application in Trading
Key RSI Strategies

Neutral Zone (50 Level)
- Acts as dynamic support/resistance
- Breakouts above/below 50 often signal trend continuations
Divergences
- Bearish: Price makes higher highs while RSI makes lower highs
- Bullish: Price makes lower lows while RSI makes higher lows
