RSI is important because it provides valuable insights into market momentum and helps traders identify potential entry and exit points. When an asset’s RSI reaches extreme levels (above 70 or below 30), it may indicate that the asset is due for a price reversal. For example, an RSI above 70 might suggest that the asset is overbought and could be due for a pullback, while an RSI below 30 might indicate that the asset is oversold and could be poised for a rally. Traders often use RSI in combination with other indicators or chart patterns to confirm trends and strengthen their trading strategies.
