Online foreign exchange trading is massively popular and many stock traders are making the switch.

The currency market is big, with about $4 trillion traded about each business day. That is more than all of the stock exchanges of the Earth combined. At the same time, the number of currency pairs available for trading is limited with about ninety percent of the total trading occurring in 10-20 currency pairs.

Compare this with the quantity of stocks that can be traded in only 1 country, and it is clear that the major currency pairs have many, many times the liquidity of any stock. However big some of the investment funds of the big global banks might be they do not hold much power individually in a trillion dollar market. It is simply impossible for any institution to regulate the cost of a currency pair in the way that company stock costs can be manipulated. For a similar reason, illegal trading is not the problem that it is in the market.
