I am analysing some trading strategies, so lots of high quality data is needed. I have been using yahoo finance which provides a lot of high quality daily data on stocks and indices.
Currently I am interested in index data S&P500 total return and so on. I'd prefer total return data sets. Unfortunately yahoo finance doesn't provide data for a wide range of countries or at least not with the quality I want. I couldn't get complete data from danish stock market index from 1988 to 2017 for example.
So do you now any free data provider where I can get high quality data on stock markets? my criteria are:
a) necessary
- Data must be correct
- as few gaps as possible (week ends and holidays is ok)
- daily data
- time frame ranges from approximately 1988 to 2017 (1 or 2 years less is still ok)
b) nice to have:
- Total return of the index
