RSI measures the speed and magnitude of recent price changes on a 0-100 scale, identifying overbought and oversold conditions — it is one of the most widely used technical indicators in every market. RSI divergence signals are especially powerful when confirmed by the MACD or volume-based oscillators. Traders in crypto often widen the overbought/oversold thresholds to 80/20 due to higher volatility. Combine RSI with sound trading psychology to avoid chasing overbought entries in trending markets.
RSI = 100 − [100 / (1 + RS)], where RS = average gain over N periods / average loss over N periods. The default period is 14. Values above 70 are overbought; below 30 are oversold.
The Force Index combines price change and volume into a single oscillator that measures the power behind each market move — positive force indicates buying pressure and negative force indicates selling pressure.
