Ya blagodariu Vas, Ivanovich, you will never be a successful trader if you can't follow a logical argument. My point was not that earthquakes are "emotional", but that you can get unpredictable (i.e. apparently irrational) behaviour out of completely deterministic (i.e. totally rational) systems. It's also called chaos theory or complexity theory or computability theory or the "butterfly effect".
Each of us, as a trader, tries to analyse the market rationally and make rational trades. But there are millions of us, each of us has our own theories, and what actually happens is the sum of all those theories, which is unknowable. I think - for rational reasons - that USDCAD is way underpriced and will be back to 1300 or more pretty soon. Other people have their own rational theories, which predict parity by the end of the year. Who's right? Who knows.
Fortunately for our sanity, the behaviour of currencies is not entirely at the mercy of speculators. Unlike stocks, which no-one buys for any reason except to make money, money itself is actually useful stuff, which people need from time to time. You land at the airport at Dubai and you have to turn your loonies into Dubai whatsits, you know you're going to get ripped off, but what choice do you have? Similarly, you're doing business in Canada, and you have a nice lump of loonies that you'd like to hang on to because the loonie is going up and up, but you can't, because you have payrolls to meet etc. You may have American suppliers or subcontractors who want to be paid in USD, and you have to convert your loonies, no matter how disastrous the rate.
Anyway, all the pundits (I mean the serious ones, like the Bank of Canada, not some hack writing in the Mope and Wail) agree that CAD is a resource-driven currency. I have my own model, which correlates 93% with historical behaviour. As a rough indicator, spot oil prices will do: not only is oil our single biggest export item, but what the specs do to oil prices, they tend do to other resources as well. Oil is down to $61-$62, whereas during the big slide it was going from $51 to $66. It is still (a) way lower than it was the last time the loonie was over 90 cents, and (b) way higher than it was when the resource boom started, around 2002. Back then, it was going for $20-30, and even if the fundamentals drive it up at 10% a year, it should still only be around $40, not in the 60s. So the indications are that $60-70 oil was a speculative fad, a bubble which is now bursting as all bubbles do, especially as the US economy slows down. A slower US economy means a lower trade deficit means less demand for the loonie means USD is going up. Remember that during the 2000-2001 recession, USDCAD went over $1.60.
The "parity" bunch I think are just drawing trend lines on their charts and figuring that down, down, down in the past means down, down, down in the future too. Then they find rationalizations for their superstitious beliefs. They seem to be dominating the market right now. But realities will eventually catch up with them.
That's my entirely rational theory, anyway. Like any theory (except evolution) it has a good chance of being wrong. But I've yet to hear another that makes sense to me. Assuming that the market behaves like your 2-year-old is no way to make money.
BTW, despite the fact that everything has gone wrong for me this month, I'm at this point only $300 down. Given average luck, by the end of the month I'll be RICH! RICH! Well, semi-solvent, anyway.
