Here the great advantage is that you can trade with small amount of money. With some brokers, as little as 100$ which allows you to control
up to 1000$.
comparing that with purchase stock. If suppose you purchased $10,000 stock, you would have to have a minimum margin of $5,000. That's a great and huge advantage.
the another advantage is that the currencies are often trend for weeks, months and sometimes even years too. just catch and understand the trend and you are on way to some nice profit.
The one more advantage i.e, third advantage is that currencies suddenly don't gap up or down with news of the day as stocks do. There are no problems likes accounting, scandals, earning rumors, insider trading or take over bids etc.
The another big advantage is that you can trader 24hrs a day, almost 6days a week or a week....... :-)
