First: you should adapt to his current mood.
Second, you should be prepared with both hands. 1. The futures market doesn't have to lose money. You have studied abroad, so your knowledge is natural. You can ask him to study more and help him sum up his studies. You should also know more about this, or tell him some normal investment ideas, so that you may help him make some money (at least lose less) and reduce the financial pressure on your family. If you want to be friends with your father and be good friends, you must not quarrel with him. In this way, he will think that you are helping him, and you must touch him with your heart. No matter how you solve the problem, you can't quarrel. Normal problem-solving quarrels will not bring back results. After a certain period of time, you will slowly tell him to give up futures foreign exchange. Maybe by then, he may be moved by you and give up.
Third: No matter what the result is, you have to do it. Wish you success! ! !
