Hi Gcicceri,
It is my understanding that you wish to know an efficient approach to retrieve large number of stocks data of multiple series from the “FRED” data server using the fetch function in Computational Finance Toolbox.
To address your query, instead of using a loop, you can pass the array of series directly to the “fetch” function and retrieve a (1 x number of series) structure from which data of a series can be retrieved as below.
x=fetch(c,series,t0,t1);
x(i).Data;
Here "i" is the index of a series in the series array
Refer to the documentation on how to request data from FRED server as follows
Hope this helps.
