Hi Jack,
Yes, that works well for Canadian stocks, but it wouldn't work for other non-US (e.g. UK or Australian) stocks. I'm looking for one source that allows all historical data to be retrieved and right now Yahoo! is the best.
By adding suffixes, you're able to retrieve quotes from all types of exchanges. I remember an AI user sending me an email telling me how excited he was that AI worked with his exchange (an exchange that I'd never even heard of).
The workaround right now is to use the CA: prefix, however I'll be working to move the Fundamental Analyzer over to Yahoo! for SP1. Then the syntax for all quotes will be the same.
I'll look for your email about the data source you mentioned. Anything that will reduce the need for patches is a good thing in my book. Thanks!
BTW, my email address is mhing@automaticinvestor.com
