To compute Chaikin Money Flow (CMF) using Erlang, you can follow these steps:

1. Define the necessary variables:

% High, Low and Close prices
High = [100, 110, 105, 115, 120],
Low = [90, 100, 95, 105, 110],
Close = [95, 105, 100, 110, 115],

% Money Flow Multiplier
MF_Multiplier = ((Close - Low) - (High - Close)) / (High - Low),

% Money Flow Volume
MF_Volume = MF_Multiplier * Volume,

% ADL Array
ADL = lists:scanl(fun(E, ADL) -> ADL + E end, hd(MF_Volume), tl(MF_Volume)),

% CMF Array
CMF = lists:sublist(ADL, length(ADL) - N),

% CMF Calculation
CMF_Result = lists:nth(N, CMF).

1. Specify the length N for the CMF calculation.
2. Calculate the Money Flow Multiplier (MF_Multiplier) using the formula: (Close - Low) - (High - Close) / (High - Low)
3. Compute the Money Flow Volume (MF_Volume) by multiplying the Money Flow Multiplier with the trading volume.
4. Calculate the Accumulation Distribution Line (ADL) by summing up the Money Flow Volumes over time.
5. Calculate the Chaikin Money Flow (CMF) by selecting the last N elements from the ADL array.
6. Retrieve the CMF result by accessing the N-th element from the CMF array.

These steps should help you in computing the Chaikin Money Flow using Erlang. You can adjust the variables and formulas as needed based on your specific requirements.
