MetaTrader 5 Platform Update Build 1045: New WebRequest

Trading Terminal

1. Preparatory works for virtual hosting support in MetaTrader 5 platform. Virtual hosting service allows you to rent a terminal that operates around the clock with no interruptions directly from your MetaTrader 5. One of the main features is selection of a server located closest to the broker's server minimizing network latency.
   

   
   
   

   
   

2. Tester agents now can work only in the 64-bit systems. This decision is driven by the need to follow the development of the IT industry. Switching to the new technologies increases computing performance and enables further development of MQL5 Cloud Network.

   
   
   

   Changes in the platform components:
   

   • Remote agents and MQL5 Cloud Network agents are no longer available for use in the 32-bit terminals. Instead of the agent list, "Available only in the 64-bit version" message is displayed.
   • MetaTester 5 Agents Manager is available only in the 64-bit version. Thus, it is possible to install the agents only on the 64-bit systems.

   
   

3. Fixed news filtration by language when the language list is specified manually in the terminal settings.
4. Optimized work with a large number of open orders.
5. Accelerated sending trade requests.
6. The interface has been adapted for high resolution screens - Full HD and higher.

MQL5 Language
