Hi Members Couple of quick questions please.
These questions refer to End Of Day Data please. 1) I am setting up my EOD stock database for the first time. I am given the opportunity to download 7700 stocks into my US-Stocks database using AmiQuote as a downloader from Yahoo historical data. The AmiQuote downloader will download EOD data on any time frame I input. Ideally it would be nice to download all available data from all stocks and indices. However not only would it take a couple of days but would probably take up a ton of space as well. I have the time and the space for this procedure but is this the correct way to start building a data base? Or would I be better off only downloading 2 years of EOD data for each symbol and then if I need more data for a specific symbol then I would simply go back and download it from Yahoo. I understand that the time frame I should download is dependent on what i am trying to back test. Can someone please explain the mind set of setting up a stock database? In other words, its the time frame for each symbol I'm deciding on. 2) I downloaded historical EOD data on The Dow Jones Industrial Avg. ^DJI. The data goes back to 10/1/1928. The download was successful but when I brought up the chart, I noticed between the years of 1928 and 1930 there are dashes (something like open or close markers without the bars). From 1930 onwards to Dec. 2007 the chart is normal(shows OHLC Bars). Why are these dashes present instead of OHLC Bars? Thank You Walter
