This is an RCI 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.
[RCI]
The RCI (Rank Correlation Index) is an indicator that quantifies the degree of correlation (linkage) between the "rank of date (time)" and the "rank of price" within a calculation period, expressing it on a scale from -100% to +100%. It reaches +100% if "the price continues to rise consecutively every day," and -100% if "it continues to fall consecutively every day." Because it ignores the "magnitude of price fluctuations (volatility)" and extracts only the "fact of whether it went up or down (rank)," it produces a uniquely smooth line and is highly resistant to market noise (such as sudden wicks).
