MetaTrader 5 Platform Build 1745

MetaTrader 5 build 1745 will be the last platform version supporting Microsoft Windows XP/2003/Vista.

A few months ago, we announced end of support for older versions of operating systems. Windows 2003, Windows Vista and especially Microsoft Windows XP are outdated operating systems. Microsoft ended support for Windows XP three years ago, because potential hardware capabilities could no longer be realized on this system due to technical limitations.

MetaTrader 5 build 1745 and older versions will continue to work on the above operating systems, but will no longer receive updates. Platform installers will not run on these operating systems.

The minimum required operating system version for running MetaTrader 5 is Windows 7. However, we strongly recommend using the 64-bit version of Windows 10.

Terminal

1. The /auto key has been added to the installer, allowing to install the program in automated mode without additional actions required from the user. When the installer is launched with this key, installation settings will not be shown to the user, and the terminal will be installed at the standard path, with the standard Start menu folder name for the program. Example of such launch:
   
   C:\mt5setup.exe /auto
   
2. Fixed installer operation in cases when the user does not have appropriate operating system permissions.
3. Fixed excessive consumption of CPU resources when no actions are performed in the terminal (when there are no open charts and no actions are performed by the user).
   
4. The new version features automatic compression of *.log files at the file system level. The new functionality allows reducing the amount of disk space used by logs.
   
5. The amount of cache during single test runs has been increased. This provides faster testing in 64-bit operating systems.
   

Tester

1. Fixed optimization of trading robots using the MQL5 Cloud Network. Issues could arise with products purchased from the MetaTrader Market.
2. Fixed calculation of spreads for bars generated in the "Every Tick" testing mode.
3. Fixed selection of OpenCL devices in the strategy tester. Now, the visual tester is allowed to access all available OpenCL devices.
4. The new version features automatic compression of *.log files at the file system level. The new functionality allows reducing the amount of disk space used by logs.

MQL5

1. Fixed deletion of bars of a custom symbol using the CustomRatesDelete method.
