Note
- Market Orders/Limit Orders
According to the price limit rules, buy and sell orders have maximum and minimum prices, respectively. The price limit rules for market orders are consistent with those for limit orders. In cases of low market liquidity, market orders may not be fully executed and may be partially canceled. Limit orders exceeding the price limit rules will be canceled.
- TP/SL and Conditional Orders
After the TP/SL and conditional orders triggering, if the limit orders and market orders hit the price limit rules, these market and limit orders will be canceled.
