Details of Chaikin Money Flow (CMF)
Chaikin Money Flow (CMF) is a volume weighted average of Accumulation/Distribution over a specified period, which is usually taken to be 21 days. The CMF offers a volume weighted indicator on the following two principles:
- The nearer the close is to the high the more accumulation is taking place.
- The nearer the close is to the low the more distribution is taking place.
The CMF indicator is evaluated for the following steps:
- Evaluate the Volume Weighted Accumulation/Distribution over each of the days within the
period considered for the calculation. The Volume Weighted Accumulation/Distribution on each
day is given by:
(((Close - Low)-(High - Close))/(High - Low)) * Volume
- Sum the Volume Weighted Accumulation/Distribution over the period and the divide the result by the sum of the volume over the period.
Example of Application
Within this example we illustrate the way this method works when we consider a given 10 period in which the length of period over which the CHM is evaluated is 4. In this case the result will be an array of 7 elements as follows:
- result: CMF calculated over the last four periods
- result: CMF calculated over previous four periods
- result: CMF calculated using the periods between the earliest period and the fourth from earliest period.
