Understanding the Simple Moving Average (SMA)
The Relative Strength Index (RSI) is a momentum oscillator developed by J. Welles Wilder. It measures the speed and magnitude of price changes to evaluate whether an asset is overbought or oversold.
RSI values range from 0 to 100. By default, a 14-period setting is used, which analyzes the average gains and losses over that period. The RSI doesn't just show whether price is high or low — it gives insight into how strong or weak recent momentum is.
In crypto trading, RSI is especially valuable because it helps:
- Identify when assets are potentially about to reverse
- Spot weakening trends before price reacts
- Time entries during overextensions
