OANDA is a currency exchange outfit where you can trade currencies. (For those that do not know)
It is something to keep an eye opened for when a major player in the currency exchange world decides to halt trading just to see what is going to
happen in the Greece elections.
My personal opinion is that the Euro is going to be smacked around and a lot of people are going to lose major funds.
It is also sad that trading is going to be closed as it is an opportunity to rake in some MAJOR pips!
The link below is directly from OANDA explaining their reason for closing.
