The best benefit of Forex trading is that you can trade any time of the day and night. The Forex market remains open for 5 ½ days in a week. Hence even if you are working you can still trade in Forex after your office hours and even early in the morning.
The Forex trading system works on a network of computers that are linked to each other globally. When the particular bank open in the day for business it joins the computer network through the internet. The bank’s asking price and the bid then becomes a part of the currency market. The compute system then combines the bids form all over the world and organizes all data in a form which people can understand.
When people can see the currency prices moving it is actually the different banks that are bidding and asking for prices. The banks are located in different parts of the world. When banks in Asia are awake and doing business, the banks in the US close. When the Asian banks are about to close the European banks open. This is a continuous process and it stops only during the weekends.
When you engage your broker to buy or sell currency, he will route your order to the computer network of the bank and the order is procured at the price that you have mentioned. Your broker wont tell you where in the world the order was filled but it should not matter to you as long as your order is filled.
