The finance charts on Yahoo! Canada do not seem to be working correctly. They seem to be pointing to the US web site and do not work.
Example:
1. Go to ca.yahoo.com
2. Click Finance on left nav
3. Look up a symbol, e.g. KO for Coca Cola
4. Go to Basic Tech. Analysis chart
5. Try to change some of the parameters, e.g. select 20 on moving average

At this point you see that the browser spends a long time trying to load something. Eventually it fails and if you look at the address bar, there appears to be an invalid URL there, looking something like this:

https://us.rd.yahoo.com/finance/chart/sma/20/*http://ca.finance.yahoo.com/q/ta?s=KO&t=1y&l=on&z=l&q=l&p=m20&a=&c=

I'm pretty sure that URL is malformed.

Please fix :)
