Hi, I fear I may ask a dumb question, but I don't really understand how to get the historical quotes from Yahoo for all the quotes on NYSE and NASDAQ... I looked at http://www.amibroker.org/userkb/2007/11/09/setup-a-custom-database-nasdaq/ but it is still not too clear for me...
To Howard: at long term I will use DTN, but DTN is 100$+/month with canadian quotes, so it is somewhow expensive for now... And I think that the EOD data should be quite the same... I'm still figuring how I can integrate intraday-EOD data in the same interface, so right now I have an EOD database with DTN and an intraday database with DTN. I would only add a Yahoo EOD database to the whole thing. Thanks!
