Choosing the best data centre in MT4
Icons showing Data Center or a direct connection.
If your broker does use multiple datacentres then MT4 will attempt to automatically connect to the datacentre that is closest to you when you login, resulting in faster execution time and consequently less slippage, especially during a volatile market.
It has been known that sometimes traders experience connection issues when connecting to an MT4 server, especially if they are located far away from the main server or are using an ISP that heavily restricts network traffic (such as in China). In case issues prevail traders can change the data center they are connected to in MT4 by left clicking on the Connection Status indicator. Upon clicking, a list of available data centers will appear along with the latency to each one. This allows the trader to make sure they are connected to the best datacentre for their location and if not, switch.
