Multicurrency basis
The system is designed on a multicurrency basis. It means that any currency can serve as a general currency used in the operation of the whole complex in any country and with any national currency.
Economy and productivity
Implemented data transfer and processing protocols are notable for their economy. It makes it possible to support several thousands of traders through a single server with the following configuration: Pentium 4 2 GHz, 512 DDR RAM, 80 GB HDD. New protocols reduce both the demands on datalink and their operational cost.
Reliability
In the case of damage to the historical data, the complex has backup and restoration systems. Also, the implemented synchronization allows to restore damaged historical databases within several minutes with the help of another MetaTrader4 server.
Safety
To provide safety, all the information exchanged between parts of the complex is cripted by 128-bit keys. Such solution guarantees safekeeping of information transferred and leaves no chance for a third person to use it. A built-in DDoS-attacks guard system raises the stability of operation of the server and the system as a whole.
A new scheme of system working operation was created especially for DDoS-attacks resistance. With its help, you can hide the real IP-address of the server behind a number of access points (Data Centers). Data Centers also have a built-in DoS-attacks protection system; they can recognize and block such attacks. During distributed attacks at the system, only Data Centers are attacked; MetaTrader4 Server continues its operation in regular mode. Thus, Data Centers increase the system's stability to DoS and DDoS attacks.
The implemented mechanisms of rights sharing make it possible to organize the security system with more effectiveness and to reduce the probability of ill-intentioned actions of company staff.
