Going Long

Buying a security with the intention of profiting from its rising value is known as going long in trading.

For example, in the context of forex trading, a trader may decide to go long on the EUR/USD currency pair if they think the value of the euro will rise relative to the US dollar. This simply means that they are buying euros and selling US dollars expecting that eventually they will be able to sell the euros for a greater sum.

The opposite of going long is going short — a trading strategy used to take advantage of markets that are falling in price. When going short, a trader sells a security first and then buys it back later, expecting that the price will drop and a profit can be made.
