documenentation error re Moving averages and single values?

[Dave180]

Under EFS Knowledgebase / function ref / built in / Moving Average #2064)
there is an example: "To Retrieve a Single Value"

function main() {
   myVar = sma( 10 ); 

Surely that returns a series, as the documentation above shows that the first argument is the series length?

Given that, as far as I can see, to return a single value you have to actually specify a series as you can't type:

   myVar = sma( 10,, 0 ); 

What am I missing here?

Hello Dave,

Article #2064 has been updated.

The source parameter and the bar index parameter are both optional so if you do not need to specify a source you can just specify the bar index you want to retrieve.

var myVar = sma(10, 0);

The extra comma is not necessary. The EFS2 engine can recognize that there isn't a source parameter specified and uses the close series by default.
