In plain English
What Short position means
If you are short, you gain when the price goes down and lose when it goes up. In spot FX, being short EUR/USD means you sold euros and bought dollars, so the position benefits if EUR/USD declines. Short positions are also created through CFDs, forwards, and other derivatives.
Why it matters
Short positions are central to speculation, hedging, and market making. They let traders express a view on falling prices, offset existing exposures, and manage inventory. They also matter because losses on a short can be open-ended if the market rises sharply.
Example
Simplified example: you sell 10,000 EUR/USD at 1.1000. If the rate later falls to 1.0950, the position is 50 pips lower, which is favorable to the short. If it rises to 1.1050, the short loses 50 pips.
