MetaTrader 5 build 5518 - 22 Jan 2026 Update...

MetaTrader 5 BETA build 5540 - Launch 23 Jan 2026


In this version, we have improved ONNX support in MQL5. Models now run significantly faster on GPUs with CUDA support. In addition, we introduced support for new flags and revised the library workflow: ONNX is now installed only on the first run of a program that uses it, rather than with the platform.

We have also refined the rendering of text and analytical objects on charts for the Blend2D engine introduced in the previous update. In addition, this update provides enhancements to trading reports and stability improvements to the Strategy Tester.

The web version of the platform has received several improvements as well. When adjusting stop levels directly on a chart, you can now see an approximate profit or loss value in monetary terms. We have also fixed the display of certain trading data.
