When the value is above 70, it may indicate that an asset is overbought, while a value below 30 suggests it may be oversold.Traders use oscillators to make informed buying and selling decisions. By analyzing the signals provided by these tools, they can anticipate price reversals or continuations, enhancing their trading strategies. Oscillators are particularly useful in volatile markets, where rapid price changes can lead to trading opportunities.In summary, oscillators are key analytical tools that help traders gauge market momentum and make better decisions based on price trends.
