This module introduces the Relative Strength Index (RSI), a powerful momentum oscillator used to evaluate the strength and speed of price movements. Learners will understand how RSI is calculated, its default settings, and how to interpret values to identify overbought and oversold conditions. The module also explains how RSI can signal potential trend reversals, divergence patterns, and help fine-tune entry and exit points. With real chart examples, learners will gain practical skills to integrate RSI into their trading strategies.
