This is a Stochastic Oscillator 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.
[Stochastic Oscillator]
The Stochastic Oscillator determines overbought and oversold conditions by quantifying the relative position of the most recent closing price as a percentage from the bottom, where the entire range from the "highest high" to the "lowest low" over a specified period is treated as 100%. It utilizes the natural tendency of prices: "during an uptrend, closing prices tend to cluster near the highest high, and during a downtrend, they tend to cluster near the lowest low." It reacts faster than the RSI and is particularly effective in ranging market environments.
