Liang Xi Yue's trading volume is 1.5 billion dollars, and many people are eager to offer Liang Zi a rebate, which makes me want to laugh. What does this level of trading volume mean? It's equivalent to a small market maker, and the limit orders at this VIP level have a negative fee rate. What does a negative fee rate mean? It means that not only do you not pay a fee when you open an order, but the exchange also pays you money.
