CapeTools Technical Analysis - Volume Indicators function list

Key TAGs | Excel Index | API Index



Chaikin A/D Oscillator : This function is contained within the Volume Indicators set of indicators.

Returns a 1-Column range.

outReal (Doubles).

(Reference - http://www.tadoc.org, http://www.ta-lib.org).

The Fast_Period and Slow_Period parameters determines the number of data points that the function will conduct it's analysis upon before moving on.

Thus if the value of the Fast_Period or Slow_Period parameter is 30, the first 30 points will be read, the analysis performed, then the 1st point is dropped and the 31st point added, analysis performed once again, then the 2nd point dropped and the 32nd point added, analysis performed etc... Both the Fast_Period and Slow_Period parameters act as sliding windows, where the window size determines the amount of data that the analysis will be conducted upon.

This function requires the input of a Technical Analysis memory data table object key, which must have been produced via a call to MakeHistoricalDB(). This function would have returned a string 'KEY' which is to be passed to the 'Key' parameter of this function.



Note: Within Excel, the function is named - CT.TA.ADOSC

Example function usage


The C# example below contains all the sub-function calls leading up to this function call. As a result, the example can contain a lot of code.

The VB.NET, J#, C++.NET, Java, Excel VBA, Visual Basic 6 (via COM) and C++ examples below contain function code stubs for the calls leading up to this function call. However, the function call for this function is displayed.
You can easily reproduce the stub functions code from the C# example.


If you are accessing this functrion via the MiniXL libraries, this function is present within the CT.QL.TechnicalAnalysis20 MiniXL Excel Addin.

Within our Excel Example Addin Generator, we have used the following QuantTools sub-functions in order to prepare the arguments needed to call the TA_ADOSC() function. If you are executing this function via the MiniXL libraries, the module addin name, (in brackets, to the right of the sub-functions listed below), indicates the MiniXL library in which the sub-function is held. You will need to load this library into your Excel session (along with any other libraries that the sub-function call within the addin requires (ie - CT.QT.Utils20 addin in almost all cases) in order for the example to compute successfully.

These are the financial QuantTools sub-function calls that are used within the examples :





The objects generated by these sub-functions are inter-connected in the following way :
