The RSI, developed by J. Welles Wilder Jr., is a momentum oscillator that measures the speed and change of price movements. Typically ranging from 0 to 100, the RSI is commonly used to identify overbought or oversold conditions in a market. An RSI value above 70 often indicates that an asset is overbought, while a value below 30 suggests it is oversold. This dual capability makes the RSI an essential component in many trading strategies, and with RSI Trader EA v1.0 MT4, traders can execute strategies based on these signals automatically.
