The position fee is a certain fee charged because you hold a position in the contract, which will be generated continuously. It's a bit like transaction fees, which will be lost. For example, it will charge 10 yuan every day (there is no position fee for domestic regular futures, at least I haven't heard of it).

The deposit is the performance guarantee required to hold the variety, not wear and tear. For example, a contract charges you a deposit of 654.38+1 00000 yuan, and after you close the position, all this100000 yuan will be returned to you (profit and loss and handling fee will be calculated separately).
