AXCEL.XTRADE.EMA function

This function is part of XTRADE functions group which is a collection of several technical indicators for creating technical trading rules. XTRADE.EMA calculates an exponentially-weighted mean EMA), giving more weight to recent observations. Since EMA indicators are calculated using their own previous values, the estimates are unstable in the short-term. As the indicator receives more data, its output becomes more stable.

Syntax

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


The AXCEL.XTRADE.EMA 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 two columns, the first column for time/date index and the second column is the values. Here is an example:

DatePrice
08/24/2020120.10
08/25/2020121.65
08/26/2020119.88

AXCEL.XTRADE.EMA function uses the second column for its calculations.

n Required. Number of periods to average over. 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 dateFormat 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 security price and exponentially-weighted means (EMA).

Here is an example:

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

In this example, we have:

=AXCEL.XTRADE.EMA(A1:B300, 10,, TRUE)

which means that our data is located at cells from A1 to B300, we set the number of periods for EMA calculation at 10 days. Also, since we use Excel standard date format, we skipped the date format entry and we would like to have visualization by setting the plot to TRUE. Here is the outcome:

As presented above, Axcel generates exponentially-weighted means and reports them in column EMA. 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 10, the first 9 EMA records show NA after execution.
