(defun calculate_stochastic_oscillator (data-points k-period d-period)
  (let* ((lowest-low (reduce #'min data-points))
         (highest-high (reduce #'max data-points))
         (%k-values '())
         (%d-values '()))
    
    (dotimes (i (- (length data-points) k-period))
      (let ((current-data (subseq data-points i (+ i k-period))))
        (let ((current-lowest (reduce #'min current-data))
              (current-highest (reduce #'max current-data))
              (%k-value (/ (- (car (last current-data)) current-lowest) (- current-highest current-lowest))))
          (push %k-value %k-values))))
          
    (dotimes (i (- (length %k-values) d-period))
      (let ((current-data (subseq %k-values i (+ i d-period))))
        (let ((%d-value (/ (reduce #'+ current-data) d-period)))
          (push %d-value %d-values))))
    
    (list %k-values %d-values)))

;; Example usage:
(setq data-points '(14 15 16 17 18 19 18 17 16 15))
(calculate_stochastic_oscillator data-points 5 3)

In this code snippet, we define a function calculate_stochastic_oscillator that takes in a list of data points, the K-period, and the D-period as input parameters. The function then calculates the %K and %D values based on the Stochastic Oscillator formula. The function returns a list of %K values and %D values.

You can call this function with your data points and specify the K-period and D-period to get the Stochastic Oscillator values.

The provided code snippet in Lisp calculates Stochastic Oscillator values based on the input parameters for data-points, K-period, and D-period. The calculation involves finding the highest high and lowest low within the data points, computing %K values, then further computing %D values. The result is a list containing %K values and %D values.

You can use this code snippet by copying it into your Lisp environment and calling the calculate_stochastic_oscillator function with your desired data points along with the specified K-period and D-period values. The function will return the Stochastic Oscillator values accordingly.
