Hello, trigger order may fail to be placed due to price limit, position limit, lack of margin, contracts in not-allowed-trading-status, network issues, system issues, etc.  Therefore, to avoid trigger order failure due to price limit mechanism, it’s highly suggested not to pre-set the trigger price too close to the limit price.
