| BTC/HKD | 20% |

The buy order price must be greater than 80% or less than 120% of the latest market price.
For example, if the latest market price of the BTC/USD trading pair is US$70,000, a limit buy order for BTC priced at US$91,000 will fail because the price is 130% of the current market price, which exceeds the 120% price limit defined by the trading rules.
