hello.
i am a student from austria in an IT/business college. this year i will write my degree dissertation about portfolio analysis. i have to write a program which performs an analysis on a given portfolio.
therefore, i need the historical prices of the stocks in the portfolio. can you please give me general information how i can access the download interface from yahoo, bloomberg (just to mention the most famous ones), ...? is there any platform which offers the market values for free?
thank you very much!
