Scalping, hedging and news trading are all allowed. You can hold buy and sell positions on the same instrument at the same time, and you can trade around news releases.
What's not allowed:
strategies we consider abusive, including those that aim for risk-free profit
market abuse, such as insider trading or misusing confidential information
If we suspect market abuse, we may cancel the trades involved, close your accounts and end our agreement with you.
During news and in volatile markets, orders may be filled at the next available price, and prices can gap.
Risk warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. Only trade with money you can afford to lose.
