I am interested in how some of you are determining how large of trades to hold long-term with respect to your capital. I can see how it makes sense to hold trades long-term due to how strong and long-lasting the trends are, but it still seems a bit scary to have those sudden large ups and downs.
I use a fixed ratio MM method for managing my trades, so the bet-sizing aspect is no more than my risk parameters will permit at any particular time. Typically, my exposure does not exceed 2% but I have increased to as much as 5% on strong moves and have held trades as long as 18 days. The sudden ups and downs shouldn't really be that disquieting if you have studied the behavior of your instrument. Currency pairs have statistically consistent max excursions, barring the odd financial or political surprise (outliers)...some pairs are more volatile than others. Knowing your particular instrument's charactristics will aid you in managing the ups and downs -- both in price and in your emotions. Scaling your positions and risk around these characteristics takes the nerve out of most trades if you have a solid plan and statistical edge.

How do you deal with this? When to enter/exit? How many contracts to trade with respect to capital? How large a stop to use? How do you know how much risk to take so you can sleep?
Having said the above, you have to find a strategy and method that work for you when you put everything together. How much risk capital you can begin with and not be nervous about losing, how flexible your broker allows you to be with position sizing (the more flexible the better), the time frames you trade in and the instruments you trade...it all depends. I'm assuming you are just starting out -- and you're starting out well by asking these questions first rather than what people usually ask, which usually centers around how they can find a trading model that will be right most of the time so they can bet the farm on every trade and turn $1K into $10M in two years.
But don't take my word for it. You can answer all of your questions by reading the following:
(1) Trade Your Way to Financial Freedom -- Van Tharpe
(2) The Trading Game -- Jones
(3) The Master Swing Trader -- Farley
There are of course many other fine books, but I'm assuming you've been donig the required reading anyway. You'll find something in each that you can take with you. Note that each has their flaws. I think Farley's book is by far the best all-around, so don't read this one last unless you are hell-bent on scalping. Van Tharpe is not a trader -- or at any rate, there is no evidence of this -- so his models are more theoretical even though he claims they are based on empirical research. Still, the models in his book are some of the best out there for the private trader. Jones offers a concrete method for managing money that I recommend to any private trader with limited risk capital. (I use a slightly adapted version of his model in my own trading.)
