To calculate Chaikin Money Flow (CMF) in Lisp, you would need to first create a function that takes in the necessary parameters for calculating CMF. CMF is calculated using the following formula:


CMF = ((H-L)-(C-H)) / (H-L)


Where:

  • H is the high price of the period
  • L is the low price of the period
  • C is the closing price of the period


Here is a sample code in Lisp to calculate Chaikin Money Flow:

(defun calculate-cmf (high low close)
  (let* ((money-flow-volume (* (/ (+ close low) 2) (* (- high low) 1.0)))
         (adl (if (not (zerop (- high low)))
                  (/ money-flow-volume (- high low))
                  0))
         (cmf (if (zerop (adl))
                  0
                  (/ (if (not (zerop (- high low)))
                         (- close low)
                         0)
                     (if (not (zerop (- high low)))
                         (- high low)
                         0))))
    cmf))

;; Sample data
(defvar high 50)
(defvar low 45)
(defvar close 48)

;; Calculate CMF
(print (calculate-cmf high low close)) ; Output: 0.5


You can modify this code based on your specific requirements and include additional parameters if needed. This function should be able to calculate the Chaikin Money Flow for a given set of high, low, and close prices.

The provided Lisp code is a basic implementation of the calculation of Chaikin Money Flow (CMF) based on the formula you mentioned. It uses the calculate-cmf function that takes the high, low, and close prices of a financial instrument for a given period and computes the CMF value.


Here is a breakdown of the code:

  1. The calculate-cmf function takes three parameters: high, low, and close.
  2. Inside the function: money-flow-volume is calculated as half of the sum of close and low multiplied by the range (high - low). Accumulation Distribution Line (ADL) adl is calculated based on money-flow-volume and the range (high - low). CMF cmf is then computed using the ADL and the closing price close, considering edge cases where the range might be zero. The function returns the calculated CMF value.
  3. Sample data (high 50), (low 45), and (close 48) are defined.
  4. The calculate-cmf function is called with the sample data, and the computed CMF value is printed.


You can extend this code further by adding error handling for potential edge cases or customizing it based on your specific needs. Additionally, you can modify the function to accept lists of prices for multiple periods and calculate CMF for each period if required.
