Using config

Method should
  // be using configurations provided in the {@link}.


I see no config mentioned in the, is this line added by mistake ?

U need to specify the config parameters related to Alphavantage API in files.
Just remeber the QEats sneakpeek ME
In which we were specifying the API Keys in seperate .sh file.
In similar way we can store all the Alphavantage related configurarions in file

wasn’t part of this

I am assuming the API_TOKEN and the URL structure is what you are trying to say ??

Yeah probably. Thats what I meant
