The SMA of RSI is a technical indicator that combines the Relative Strength Index (RSI) and a Simple Moving Average (SMA). The SMA is applied to the RSI values to provide a smoother, more stable indicator to help traders identify potential trend reversals. When the SMA of the RSI crosses above 50, it indicates that the average RSI value over the specified period is above the 50 level, suggesting bullish momentum. When the SMA of RSI crosses below 50, it indicates bearish momentum.
