Iceberg commission refers to the fact that investors, when making large transactions, in order to avoid causing too much shock to the market, automatically break up the large order into multiple orders, automatically place a small order according to the current latest buy/sell price and the price strategy set by the customer, automatically re-commission the order when the previous order is fully completed or the latest price deviates significantly from the current order price. Examples: If the floating point number of a single mean is set to 10, then: Each order is 90% to 110% of its average single order value. The order price is the latest sell price* ((1+ depth of order), a new order is placed after the last order has been fully completed, automatically withdrawn and re-commissioned when the latest transaction price is more than the depth of order*2 from the order. The order is stopped when the total transaction volume is equal to its total order number.
