International futures are legal. If domestic futures investors do international futures, they should try their best to choose foreign branches of domestic futures platforms, so as to ensure the formal legitimacy of futures platforms and avoid trading losses caused by poor foreign language proficiency. It is not illegal to do international futures. Futures is a legal financial investment and wealth management product recognized by the state, and the development of international futures market is earlier than that of China, so it is beneficial to pay attention to the platform selection when speculating international futures.
