This script is a custom indicator for use on the TradingView platform, which combines the Relative Strength Index (RSI) with a moving average applied to the RSI itself to smooth its movements and potentially identify trends or reversals more clearly.
The RSI is a momentum oscillator that measures the speed and variation of asset price movements. RSI values range from 0 to 100 and are generally considered overbought when above 70 and oversold when below 30. In our indicator, we adjust these levels to 80 and 20, respectively, to avoid premature or delayed signals. Furthermore, we have inserted customizable options within the script that allow the user to define their own overbought and oversold thresholds, thus improving compatibility with different strategies and market conditions.
The overbought metric means that the price may be at a point of downward reversal, while an oversold state may indicate an imminent upward reversal point. These levels are visualized as dotted horizontal lines on the indicator chart for guidance.
To capture the behavior of the RSI over time, we apply a simple moving average (SMA) to the RSI values, thereby smoothing the RSI graph and highlighting the broader trend of oscillator movement. This helps filter out the noise from smaller price movements and provides a clearer representation of trend momentum.
Regarding alerts, the indicator is programmed to send notifications when the RSI value crosses the defined overbought and oversold levels. This means that when the RSI drops below 20, the indicator triggers an oversold alert, while an RSI above 80 triggers an overbought alert. These levels, however, are user adjustable in code, allowing custom levels to be defined to match individual strategies.
Visually, the indicator plots two lines on the chart below the main price chart: a blue line for the RSI values and an orange line for the RSI moving average. The red (oversold - 20) and green (overbought - 80) horizontal lines delimit the critical levels, although these are also customizable. These are the fundamental features of this indicator that make it a useful tool for analyzing momentum and potentially identifying price reversals.
