A Question About The U.S. Dollar

OK everyone... I need your input!!

I have a wee bit of U.S. stashed (not that much... sigh) and I want to sell it when the exchange rates will give me the most profit. At the moment the greenback is worth about $0.09 more than our loonie.

Yesterday it was worth $0.10 more, which makes me think I should sell now because maybe it's sliding? Dunno. Any thoughts?

There are certain things I understand, like dollar cost averaging, for example. I intend to continue with our mutual fund purchases through this market slump.

However the factors which influence the dollar are not something I'm up on. Help!!! Anyone have any ideas where it's going? Up? Down?

Thanks :-)
