n Friday, November 14, 2025, an updated version of the MetaTrader 5 platform will be released.
This version introduces a major upgrade to the charting engine. The legacy GDI framework has been replaced with the modern Blend2D engine, which provides significantly faster and smoother rendering of charts and indicators. With advanced rendering algorithms and hardware optimization support, Blend2D delivers crisp, detailed graphics, accurate handling of transparency, and consistent performance across all systems, including high-resolution displays.
In addition, we've expanded support for the OpenBLAS linear algebra library in MQL5, with around 20 new functions added for working with matrices and vectors.
The web version of the platform has also been improved, offering enhanced stability and security. Users can now change the display mode for volumes directly in the order book.

- Terminal: Updated charting graphics core. The legacy GDI framework has been replaced with the modern Blend2D engine.
Higher Performance
Blend2D uses modern rendering architecture and efficiently utilizes multi-core CPUs, ensuring smooth chart and indicator rendering even with a large number of objects.
Hardware Acceleration and CPU Optimization
Optimized for modern instruction sets (SSE, AVX), Blend2D significantly accelerates visualization compared to GDI, which does not support these optimizations.
Crisp and Smooth Graphics
Advanced anti-aliasing and precise color handling provide smooth lines, soft transitions, and visually clean charts, which is particularly noticeable when zooming or using high-resolution (HiDPI, 4K) displays.
Modern Effects and Transparency
Blend2D supports alpha composition and advanced color operations, enabling semi-transparent elements, shadows, and other modern graphic effects.
Unified and Stable Rendering
Blend2D provides consistent rendering across all systems, independent of OS version or video driver configuration.

- BlasL2SyMV — matrix-vector product for a symmetric matrix
- BlasL2SyR — rank-1 update of a symmetric matrix
- BlasL2SyR2 — rank-2 update of a symmetric matrix
- BlasL2HeMV — matrix-vector product for a Hermitian matrix
- BlasL2HeR — rank-1 conjugated update of a Hermitian matrix
- BlasL2HeR2 — rank-2 conjugated update of a Hermitian matrix
- BlasL2TrMV — a matrix-vector product using a triangular matrix
- MQL5: Added matrix methods that perform level 3 linear algebra calculations (matrix-vector): BLAS Level 3:
- BlasL3GeMM — matrix-matrix product for general matrices
- BlasL3SyMM — matrix-matrix product where the input matrix A is symmetric
- BlasL3HeMM — matrix-matrix product where the input matrix A is Hermitian
- BlasL3TrMM — matrix-matrix product where the input matrix A is triangular
- BlasL3SyRK — symmetric rank-k update
- BlasL3HeRK — Hermitian rank-k update
- BlasL3SyR2K — symmetric rank-2k update
- BlasL2HeR2K — rank-2k conjugated update of a Hermitian matrix
- MQL5: Fixed WebRequest issue that could, in some cases, cause the connection to a remote host to drop.
- MQL5: Fixed a rare crash that could occur when variables were not initialized.
- MQL5: Fixed a rare crash that could occur when using the IntegerToString function.
- Tester: Fixed duplication of custom events when EventChartCustom was called during visual testing.
MetaTrader 5 WebTerminal
- Added the ability to switch volume display mode in the order book. Use the button on the top panel to view volumes in lots or units.
- Fixed freezing when viewing the order book on mobile devices.
- Corrected the display of current price in the trade dialog when an operation fails (e.g., insufficient funds). Previously, a zero price could be shown in such cases.
- Enhanced data storage security in the browser.
The update will be available through the Live Update system.
