RSI Buy & Sell Signal

generates Buy and Sell signals using the Relative Strength Index (RSI) indicator on TradingView. The indicator allows users to customize the RSI period length, overbought level (default 70), and oversold level (default 30). A Buy signal is triggered when the RSI crosses above the oversold level, indicating a potential price reversal from a bearish trend, marked by a green triangle below the candlestick with the label BUY. Conversely, a Sell signal is generated when the RSI crosses below the overbought level, signaling a potential price reversal from a bullish trend, marked by a red triangle above the candlestick with the label SELL. The script also includes automatic alert notifications through the alertcondition() function, helping traders receive instant updates without constant chart monitoring.
