In general, traders earn money by buying an asset when its price is rising. However, it is possible to profit when a currency or security’s price is falling too – this is known as shorting.Resource : theinvestorscentre.co.uk
Strategies for shorting the dollar
There are a number of different ways to short the Dollar, including trading USD currency pairs on Forex or betting against the dollar using CFDs (contracts for difference). Many brokers offer leverage when you trade currencies, which can amplify your profits and losses.
To open a position, you need to deposit margin into your account with your broker. Once you have sufficient funds, you can then locate a currency pair that has the USD as the base currency, and sell one unit of the base currency for one unit of the quote currency. For example, you could go short on EUR/USD if you expected the euro to depreciate against the dollar.
During the trading process, you will borrow USD from your broker, and sell it against the quote currency (EUR in this case). When the pair’s price falls to a level where you think it should close, you will buy back the dollars from your broker and profit from the price difference, minus any trading fees. This type of trading can be extremely profitable, but it is risky, and you must only invest money that you can afford to lose. You should also always use stop-loss orders and diversify your investments to reduce the risks.
