After we receive your order, it takes a certain time (usually a few hundred milliseconds) to transmit the order to the international settlement network and complete the settlement, and finally feedback the processing result to your trading account. During this period, market prices are still fluctuating（market price remain volatile）.
Therefore, we will evaluate the possibility of maximum fluctuations within the estimated time required for clearing and set the minimum distance for pending orders. Some prices fluctuate more drastically, so they will be larger. And some products have low volatility, and we will impose very few restrictions.
