The platforms via internet allows to trade live for most brokers. Global forex trading is possible with the development of the technology. A great advantage of the forex market is Margin trading, which is basically trading with borrowed money from trader. Since you can only make profits by selling thousands of units of currencies it is impossible for traders to trade without margin trading. For example, if you want to make profits from the small fluctuations of the pound (GBP) you’ll need to buy 1 lot (which is about equal to 100,000 US dollars) and then wait for it to go up. When the pound goes up a little forex traders sell it and profit from the small gap between the original price and the sell price. Forex traders use small amount of money such as $1,000-$5,000 to invest and reap profits. If the pound decrease will lose money.
Basically this is forex – manipulating earnings on the small fluctuations. Some would say that forex is similar to gambling with money on money but the truth is that there are many forex trading systems that predict within a minute error range the future fluctuations of foreign currencies.
