First of all, you have to see whether the version you use is a simulated version provided by Wenhua Finance or downloaded from the website of the futures company. Obviously, the latter is the most stable. Most of the software provided by Wenhua Finance uses its own servers, and their servers have too many users, which leads to unstable connection, slow speed and sometimes disconnection. Then look at whether your home network is Unicom or Telecom. Choosing the right market server is very important.
