    c. If the character string is not legal, the user_def field will be automatically filled with a null value; the transaction event callback will send a reminder message.

(Note: Even if the user_def field does not conform to the rules, the order will still be submitted, but the field value will be automatically adjusted. Please refer to points b and c above for the adjustment method.)

  1. For Python Market Data Web API, exception handling has been changed to using the Exception mechanism. For details, please refer to the Python code examples in the Market Data Web API documentation.
