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. 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?
