%K Line vs Stochastic Oscillator

The %K line is the primary, faster-reacting line of the Stochastic Oscillator, calculated as the percentage position of the current closing price within the period's high-low range.

The Stochastic Oscillator is a momentum indicator that measures where the current closing price sits relative to the high-low range over a specified lookback period, expressed as a percentage between 0 and 100.
