The order amount is less than the predefined average amount of 500 contracts, so the bot buys 488 contracts of sliced order at 10130.29 USDT. If the order is not fully filled, it will be canceled directly, which means the sliced order is an IOC order. The bot will place orders constantly based on the predefined time intervals*random ratio (0.5~1) until the total filled amount reaches the predefined total order amount.
