Syntax

AXCEL.XTRADE.RUNCOV(stockprice, n, [dateFormat], [plot])


The AXCEL.XTRADE.RUNCOV function syntax has the following arguments:

stockprice Required. This is a table of stock price or any other values such as volume. The format must be a table of three columns, the first column for time/date index and the second and third columns are the values. Here is an example:

DateSecurity1Security2
08/24/2020120.1045.67
08/25/2020121.6549.88
08/26/2020119.8846.38

AXCEL.XTRADE.RUNCOV function uses the second and third columns for its calculations.

n Required. The number of periods to calculate covariance. Must be between 1 and number of rows, inclusive.

dateFormat Optional. If the date in Date columns is Excel standard date format, you do not need to provide any format, and Axcel will automatically identify the date format and applies the conversion. However, if the date is provided in TEXT format, you should define the date format for appropriate conversion. Here are the elements of the date format:

/ or - : Separators
%d: day
%m: month
%y: 2-digit year (for example 98 or 07)
%Y: 4-digit year (for example 1998 or 2007)

Here are some examples of date format:

for "08/22/2019" : "%m/%d/%Y"
for "19/08/22" : "%y/%m/%d"
for "2019-08-22" : "%Y-%m-%d"

plot Optional. The default is FALSE. If you set it TRUE, Axcel provides you an advanced interactive visualization showing securities values and covariances.

Here is an example:

when you type =AXCEL.XTRADE.RUNCOV the Intellisense guides you through required and optional (shown in brackets []) entries as shown below:

In this example, we have:

=AXCEL.XTRADE.RUNCOV(A1:C255, 20,, TRUE)

which means that our data is located at cells from A1 to B255, we set the number of periods for covariance calculation to 20 days. Also, since we use Excel standard date format, we skipped the dateFormat entry and we would like to have visualization by setting the plot to TRUE. Here is the outcome:

As presented above, Axcel generates covariance between two securities and reports them in column runCov. Also, the outcome is visualized in the task pane and ready to be expanded in your browser. In this example, since we set n to 20, the first 19 runCOv records show NA after execution.
