This is an RSI equipped with a feature that allows you to adjust when to start real-time drawing, anywhere from 0 seconds to 5 minutes before the candle closes. It also includes other useful features.
[RSI]
The RSI (Relative Strength Index) calculates the balance between the "average gain" and "average loss" over a specified period, quantifying the relative bullish or bearish strength of the current market as a percentage from 0 to 100. Rather than the absolute price value, it measures the "speed and bias of price movements (momentum)."
