RSI Buy/Sell Signals
This indicator generates buy and sell signals based on the Relative Strength Index (RSI). It works by calculating the RSI value over a 14-period length and then checking if the RSI drops below 30 (oversold) or rises above 70 (overbought). When it’s oversold, the indicator plots a green upward arrow suggesting a potential buy. When it’s overbought, it plots a black downward arrow suggesting a potential sell. In essence, it helps traders spot possible reversal points using RSI levels directly on their charts.
