For example, suppose the soybean meal is 29 14 tons, and you have 3000 yuan in your current account. If you buy primary soybean meal (10 ton), the deposit will be calculated at 14%, and it will cost 29 14 yuan, plus the handling fee (calculated at primary 5 yuan) and 8 1. You should make up the deposit before the opening of the next day. If you fail to cover the position, the futures company will force the position to be closed when they think it is appropriate.
