What is your rebate?

Look at my friend, he went to work illegally for the exchange, he's using just under 2000 U to trade contracts, and in about 3 months, he racked up over 10,000 U in fees. Now his account has an unrealized loss of over 1000. He’s telling me now that he didn’t open a rebate, which I can only say is really unfortunate. If there was a rebate, it would have been a guaranteed profit, netting several thousand U. My friend is also a typical example; many people, if your account is break-even, then if you open a rebate, you are definitely net profitable. Even if you, like my friend, have a slight unrealized loss, with a rebate, you would still be net profitable.
After my friend opened the rebate, he used another 500 U, and after a month, the fees accumulated to over 1500 U. Considering the rebate, that becomes net profitable. I’ve posted the method to check fee expenditures below, so everyone can check their own fee expenses.
So everyone must absolutely open the rebate; otherwise, you will really lose out. What should have been profit turns into a loss. You must reclaim your own portion, as over the long term, it amounts to a significant sum.
