How about you FIX the Yahoo Finance so that it works?
For the last several weeks the change for the CAD/USD has been working intermittently - if at all. It seems to have quit working at all the past few days. Yesterday the value of the CAD/USD stopped working at all. How about you go back to the way you had it ten years ago? Every time you made a change - you chose to call them "improvements" - Yahoo Finance became worse.
