#让SDK中打印 submit_timing 的数据( SwqosType和 提交耗时）返回给buy 和 sell 方法。

主要解决问题：
当 wait_tx_confirmed 参数为 false 时，SUBMIT_TIMEOUT_SECS 等待改为2秒，要么全部提交完成返回，要么不等待提交未返回的交易，方便快速创建交易订单。

#Let the SDK print submit_timing data (SwqosType and submission time) and return it to the buy and sell methods.

Main problems solved:

When the wait_tx_confirmed parameter is false, the SUBMIT_TIMEOUT_SECS wait is changed to 2 seconds. Either all submissions are completed and returned, or the unreturned transactions are not waited for submission, which facilitates the rapid creation of transaction orders.
