Works very well when called once or twice. But on third call of this function it scans incomplete data from google. For example -- called this function to gather data for 5 stocks with 5 years. On the third stock it gathers only 3 years worth of data and then halts.
Also, is there a site where I can get list ticker symbols that google uses for its website. I was unable to find ticker symbol for S&P500 index.

Thanks for this great file.
