To calculate Chaikin Money Flow (CMF) using Clojure, you will need historical price data and volume data. Here's a simple example of how you can calculate CMF using Clojure:

  1. First, you need to calculate the Money Flow Multiplier (MF Multiplier) and Money Flow Volume (MFV) for each period.


MF Multiplier = ((Close - Low) - (High - Close)) / (High - Low) MFV = MF Multiplier * Volume

  1. Next, you need to calculate the Accumulation/Distribution Line (ADL) by summing up the MFV for each period.
  2. Finally, calculate the Chaikin Money Flow (CMF) by dividing the ADL by the sum of volume for the specified period:


CMF = (ADL / Sum of Volume) * 100


Here's an example implementation of the above steps in Clojure:

 1

(defn calculate-mf-multiplier [close high low]
  (let [numerator (- (* (- close low) (- high close)))]
    (/ numerator (- high low))))

(defn calculate-mfv [close high low volume]
  (* (calculate-mf-multiplier close high low) volume))

(defn calculate-adl [mfv]
  (reduce + mfv))

(defn calculate-cmf [adl total-volume]
  (* (/ adl total-volume) 100))

(defn calculate-cmf-for-period [prices volumes]
  (let [mfv (map (fn [[close high low] volume] (calculate-mfv close high low volume)) prices volumes)
        adl (calculate-adl mfv)
        total-volume (reduce + volumes)]
    (calculate-cmf adl total-volume)))


You can then use this function by providing historical price data as input:

1
2
3
4
(def prices [[100 110 90] [105 115 95] [110 120 100]])
(def volumes [1000 2000 1500])

(println (calculate-cmf-for-period prices volumes))


This code will calculate the CMF for the specified historical price data and volume data. You can modify the input data to calculate CMF for different periods or intervals.
