MetaTrader 5 Platform Update Build 5660: Improvements and Fixes

MetaQuotes, 2026.02.27 08:48

On Friday, February 27, 2026, an updated version of the MetaTrader 5 platform will be released.

This version improves operations with proxy servers. We have enhanced HTTP and SOCKS5 protocol support to reduce connection errors. The outdated SOCKS4 protocol is no longer supported.

We have also revised operations with the OpenBLAS linear algebra library. Its implementation is now delivered as a separate file: openblas.dll.

• The size of the trading terminal and tester executables has been reduced, helping you save bandwidth during platform updates. Since OpenBLAS is updated far less frequently, you will not need to download it each time.
• If multiple platform instances are installed on a computer, they will all use a single shared library file. This saves disk space.
• If OpenBLAS functionality is not used, the library is not loaded into memory, reducing resource consumption.

The update will be distributed via Live Update.
