According to the information provided by the landlord, I infer that the software deposit used by the landlord is 1 1%, and the handling fee for soybean meal is 9 yuan (unilateral).
However, when making a firm offer, both the deposit and the handling fee can be adjusted.
Generally, the margin of an exchange is 8%, and futures companies generally increase it by 2% to control risks, which is 10% for customers.
The handling fee varies according to different varieties.
When making a firm offer, if the customer does not ask for adjustment of the handling fee, the futures company will generally charge twice the handling fee of the exchange.
I wonder if the landlord can understand this.
