I have a question.

1. In forex trading, I am trading other currencies, so in a spot option, (lets say I am buying Yen) means I will be buying "units" of yen by paying with my RM rite?How long do i get before i am needed to pay this RM ?? So at the same time, I am holding this Yen, how long should I hold?? (assuming that the Yen goes up in 2 weeks time)

2. While i am holding the above units, i can also buy a "put option" to protect my self incase the Yen drops in 2 weeks time rite??

3. Anyone can roughly explain about forward/futures contract? Is it meaning that I can choose to buy e.g Baht in 4 mths time at a "pre-set" rate (could be lower than the current currency rate), and when the time comes, if the Baht appreciate, I actually untung cause, I had already pre-purchased earlier at a lower rate, correct?? for this Can I buy a "call option" to protect myself too?
