What does WMA with period = 1 mean?

Hi all,

I happen to read an article where it tells to use a WMA indicator with period = 1. Is this a nonsence? This means no smoothing and it is the same as the price itself. Right?

1. Yes. EMA(1) = SMA(1) = WMA(1) = Price.
2. It is sometimes used in code as short cut, to select which price:

   input ENUM_APPLIED_PRICE    Price = PRICE_CLOSE;
   :
   double price=iMA(NULL,0,1,0,MODE_SMA, Price, i);
   line[i] = function(price);
