WHAT DOES IT MEAN HAVE LONG OR SHORT POSITION ?
A trade is an exchange, where one currency is given up or ‘sold’ against another one which is received or ‘bought’. The act of selling the base currency is called going ‘SHORT’, the investor believes that its value will drop relative to the counter currency in order to buy back and close his trade. In the reverse case, the buyer goes ‘LONG’ the base currency, expecting a rise in its value to sell at a higher price.
