The Greatest Currency Trades Ever Made

The foreign exchange (forex) market is the largest market in the world because currency is changing hands whenever goods and services are traded between nations. The sheer size of the transactions going on between nations provides arbitrage opportunities for speculators, because the currency values fluctuate by the minute. Usually these speculators make many trades for small profits, but sometimes a big position is taken up for a huge profit or, when things go wrong, a huge loss.
