Data Center is a proxy server and designed as connecting-link between the system server and clients' terminals. It is designed as a Microsoft Windows NT/2000/XP/2003 service and can serve queries of client terminals without carrying them to the real server. Thus, using data centers allows you to eliminate the connection from client terminal to main server.
MetaTrader 4 Data Center is intended to:
Enhance the system's ability to change scope and efficiency
Data centers can accumulate historical data which can automatically be accessed by traders.
Thus, the Data Center processes a historical data query without carrying it to the system server. This reduces the load on MetaTrader 4 Server and so it can attend more traders.
Increase the resistance to DDoS (Distributed Deny of Service) attacks
Data Centers can perform as connecting server hiding the real IP-address of MetaTrader 4 Server. In this case, if one of the Data Centers is downed as a result of DDoD attack, the main system server will continue working in regular mode. At the same time client terminals that are linked to the address of the downed server, will be automatically redirected to reserve Data Centers.
Saving of traffic
Using Data Centers you minimize incoming dealing hall traffic. The program downloads data that are common for all traders in the hall: quotations, news and historic data. In this case, the amount of Internet traffic is independent to the number of traders connected to the Data Center.
