Long Position or Open Buy
When we refer to something being long, we understand it as going up. Long position means
buying a currency with the expectation to sell it at a higher price.
Short or Open Sell
When one currency in a pair is rising in value, the other currency is declining, and vice versa. If a
trader thinks a currency pair will fall he will sell it and hope to buy it back later at a lower price.
This is considered a short position, which is the opposite of a long position.
