The Right Data Source

For each market data time series of interest, the user is advised to determine the right data source as the data sources Spearian for Excel provides may return slightly different data sets.


General Guidelines:

1.For financial analysis of historical securities data, Yahoo!'s feed with the Adjusted Close column used is the most suitable source as that column incorporates dividends, stock splits etc.

2.For financial analysis of live securities data, Google feed is the most suitable source as the prices are live without any delay

3.For macroeconomic analysis, Fed's Fred is the most suitable source


The primary data sources by Asset Class are:

1.Currencies - Open Exchange Rates

2.Macro Data - Fed's Fred

3.Equities, Indices - Google, Yahoo!

4.Everything - Quandl
