Just like stocks, you can trade currency based on what you think its value is (or where it's headed). But the big difference with forex is that you can trade up or down just as easily. If you think a currency will increase in value, you can buy it. If you think it will decrease, you can sell it. With a market this large, finding a buyer when you're selling and a seller when you're buying is much easier than in in other markets. Maybe you hear on the news that China is devaluing its currency to draw more foreign business into its country. If you think that trend will continue, you could make a forex trade by selling the Chinese currency against another currency, say, the US dollar. The more the Chinese currency devalues against the US dollar, the higher your profits. If the Chinese currency increases in value while you have your sell position open, then your losses increase and you want to get out of the trade.
Oh yeah Tim - once I saw Robs post that he "didn't find second best trader here" and a picture of barclays bank this was a big red warning for me - Rob is so stupid that he can't even see difference between "barclay hedge" and barclays bank - any serious trader wold know this - so I bet with everything I have Rob is NOT a trader and NEVER traded profitably. So cheap of you to attack Jarrett - it is you who look like an idiot not Jarrett rob booker backtesting
A spot market deal is for immediate delivery, which is defined as two business days for most currency pairs. The major exception is the purchase or sale of USD/CAD, which is settled in one business day. The business day calculation excludes Saturdays, Sundays, and legal holidays in either currency of the traded pair. During the Christmas and Easter season, some spot trades can take as long as six days to settle. Funds are exchanged on the settlement date, not the transaction date.
