To avoid extreme conditions and protect the interests of traders, KuCoin introduced Immediately Executable Price Range (IEPR) in both the spot market and futures market.

KuCoin has set a Price Range for all trading pairs to limit the impact of large taker orders on the market to a certain range. Once a taker order is to exert an influence beyond that range, the unfilled parts of the order will be immediately canceled and will not influence other orders in the order book.

In the spot market, if the final execution price of your order deviates beyond the Price Range from the order price you placed, then IEPR will be triggered. In the futures market, if the final execution price of your order deviates beyond the Price Range from the mark price in your order placing, then IEPR will be triggered.
