dotnetCHARTING Namespace > FinancialEngine Class > ChaikinMoneyFlowOverPeriod Method : ChaikinMoneyFlowOverPeriod(SeriesCollection,Int32) Method


sc
A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.
lengthOfPeriod
An integer which represents the number of periods over which the indicator is calculated.
Iteratively evaluate the Chaikin Money Flow (CMF)indicator over all (sub)collections of periods of a given length for all periods for which data is provided.

Syntax

Visual Basic (Declaration)  
Public Overloads Shared Function ChaikinMoneyFlowOverPeriod( _
   ByVal sc As SeriesCollection, _
   ByVal lengthOfPeriod As Integer _
) As SeriesCollection
Visual Basic (Usage) Copy Code

)

Parameters

sc
A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.
lengthOfPeriod
An integer which represents the number of periods over which the indicator is calculated.

Remarks

In particular, this method returns an array where the 1st term of the CMF indicator for the latest period, the second term of the CMF in the previous period and so on. Please note that the CMF will be evaluated for all periods for which there is sufficient data (see example below for more details).

Remark: The form in which the Chaikin Money Flow (CMF) in provided here is particularly suitable when wishing to integrated this functionality within a Client side GUI Charting Application.

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.

Evaluation

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[0]: CMF calculated over the last four periods
  • result[1]: CMF calculated over previous four periods
  • ...
  • result[7]: CMF calculated using the periods between the earliest period and the fourth from earliest period.
