The RSI value ranges from 0 to 100, typically calculated over a period of 14 days. When the RSI is above 70, it usually indicates that the market is overbought and there is a risk of correction; below 30 indicates that the market is oversold and there is a potential for a rebound. These are key signals for determining market turning points.
RSI derives the Relative Strength (RS) value by comparing the average gains to the average losses, and then calculates the index using a formula. When the strength of the uptrend is greater than that of the downtrend, the RSI value rises; conversely, it falls.
Traders can use the RSI to determine whether the market is in an overbought or oversold state and predict potential trend reversals through divergence signals (such as a new price high without a corresponding RSI increase). Additionally, the 50 line can serve as a reference for bullish and bearish trends.
RSI is simple and intuitive to operate, making it suitable for beginners, and is often used in conjunction with other indicators to improve accuracy. The downside is that in a one-sided market, RSI can easily remain at high or low levels for an extended period, necessitating a comprehensive analysis in conjunction with trading volume and K-line patterns.
RSI is like a thermometer for the crypto market, quick and intuitive, but one cannot determine the fate of the market solely based on a high fever or low temperature. It should be placed within a larger diagnostic framework: confirming the pulse with trading volume, observing wounds with K-lines, and capturing turning points with divergences, to truly let this 0-100 scale realize the value of “relative strength.”
