The network disconnection we usually say is generally divided into several situations, such as man-made, natural server refresh, network reasons and so on.

1. Man-made: it will be disconnected frequently, and it will not be able to connect automatically after disconnection or the connection will be slow.

2. The server is naturally refreshed: under normal circumstances, the server is refreshed every 3 hours in turn, and there will be no connection during the refreshing process, and this will automatically connect soon, generally within 10, depending on the network. 3. Network: If the user's network has problems or the network speed is too slow, it will also cause network disconnection. Sometimes the slow response is a computer configuration problem. Usually mt4 requires more computers than ordinary ones.
