How to declare an empty Financial Time Series ?

I want to populate a FinTS in a for loop.

Before the for loop, I need like to declare an empty FinTS (with only the data names) that will contain the data parsed by the for loop.

I tried things similar to :

myFTS = fints([],[],{'Open','Close'})

But none worked. Any help appreciated.

Ok found it:

myFTS = fints();
