Binance updated its fiat trading market maker program today The main update is to change the previous single level to two levels, L1 and L2 The current proportion of pending orders and cost rates for each level are 0.5% and -0.005% for Level 1, and 1.0% and -0.010% for Level 2. And a mechanism for weekly review of market maker accounts has also been added A friend of a market maker said that Binance did not have L1 and L2 levels before, and now it may want to attract more small market makers to compete with large market makers And encourage large market makers to move up to higher levels, receive more commission incentives, and further strengthen liquidity Actually, I don't care about market makers, but it's still necessary to review the market maker account mechanism every week Last time, several market makers maliciously smashed the market to retail investors after the opening, which is still vivid in my memory Binance strengthens market maker monitoring to protect individual investors, which is quite good!
