A trade goes on from all around the globe during various countries’ business hours. Thus, you will be capable of trading major currencies any time, 24 hours a day. Because of the fact that there are no any set exchange times, this means that there is always something happening any time of the day or night.
Not like the other several financial markets where it could be really hard for you to sell short, there is no limitation in any shorting currencies. Whenever you think that it is going to go up, you can buy it. Whenever you think it is going to fall, you can sell it. In forex, this means that there is no such thing like a “bear market.” In this world, you can lose or make money any time.
Since forex is a $4 trillion market a day, and most trading focused only in a few currencies, chances are there are always several people trading. It makes it generally very easy in getting in and out of trades any time, even at large sizes.
