At present, the handling fee for glass is a one-way fee for closing positions on the same day, and the exchange charges 3 yuan. Futures companies have to add a certain handling fee, and each company is different. Add 3 cents and the money will be even lower. If the capital is large, day trading can be low! This should be discussed with the futures company. I suggest you open an account in a class A company, which has obvious advantages in transaction speed. According to the price of 1350 yuan, the general company will charge a deposit of 10%, which is roughly 1350 yuan *20 tons *10% = 2,700 yuan. I hope it helps you. You can ask me if you don't understand.
