CFDs are complex financial instruments and carry a high level of risk due to leverage. A significant proportion of retail investors incur losses when trading leveraged products such as CFDs. You should carefully consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your capital.
At-the-money (ATM) describes an option whose strike price matches the current price of the underlying asset. If your call option has a strike price of $50 and the stock is trading at $50, it is at-the-money. In this state, the option generates neither a profit nor a loss on its own.
