What Is the Relative Strength Index?

Measures the speed and magnitude of recent price changes to evaluate overbought or oversold conditions. Ranges from 0 to 100. RSI compares the average gain to the average loss over a lookback period (default 14). When gains dominate, RSI rises toward 100. When losses dominate, it falls toward 0. Above 70 is traditionally overbought; below 30 is oversold.

RSI Signals on USD/ZAR

Buy when RSI crosses above 30 from below (oversold recovery). Sell when RSI crosses below 70 from above (overbought rejection). Divergence between RSI and price is the strongest signal — price makes a new high but RSI doesn't = bearish divergence.
