A Contract-For-Difference account is illegal in the United States. These are offered by international brokers and for non-US residents. When you buy a CFD, you aren’t actually buying shares of a stock. You are buying a contract to buy x number of shares of a stock. You can then sell back the contract as the price goes up. Instead of buying actual shares, you buy contracts to buy shares. The advantage is that in theory you could buy a contract to buy 1mil shares, even if there were only 100k shares available to buy at that price at the time.
