1-10. NK-Fixed CCI

This is a CCI 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.


[CCI]

The CCI (Commodity Channel Index) is an unbounded oscillator that calculates how much the current price statistically deviates from the "average price over a specific past period." Its formula incorporates a constant of 0.015, which the developer intentionally set as a statistical benchmark so that "70% to 80% of CCI values fall between -100 and +100." Conversely, a state where the CCI exceeds +100 or drops below -100 signifies that "an exceptionally strong trend (an outlier) that deviates from the statistical norm is occurring."
