New MetaTrader 5 Platform Build 5430: Enhanced Charts Powered by Blend2D

New comment
 

On 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.

  1. 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.


    Charts are now rendered using the new Blend2D engine


  2. MQL5: Added matrix methods that perform level 2 linear algebra calculations (matrix-vector): BLAS Level 2:

    • BlasL2GeMV — matrix-vector product
    • BlasL2GeR — rank-1 update
    • BlasL2GeRC — rank-1 conjugated update
    • 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

  3. 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

  4. MQL5: Fixed WebRequest issue that could, in some cases, cause the connection to a remote host to drop.
  5. MQL5: Fixed a rare crash that could occur when variables were not initialized.
  6. MQL5: Fixed a rare crash that could occur when using the IntegerToString function.
  7. Tester: Fixed duplication of custom events when EventChartCustom was called during visual testing.
  8. Tester: Fixed the behavior of IsStopped during forced test termination.

  1. 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.

  2. Fixed freezing when viewing the order book on mobile devices.
  3. 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.
  4. Enhanced data storage security in the browser. 


The update will be available through the Live Update system.

 
I have a small request. The issue is that I open many charts—more than 24—and I undocked them. However, after I close the terminal and reopen it, only 24 of the charts remain in the positions where I undocked and arranged them the rest are docked back, and the Chart Shift points are also misaligned compared to my original design. As far as I know, this is a feature and a limitation of MT5. If possible, please increase the maximum number of charts to 50 instead of 24. Thank you, everyone.
 

Hi everyone,

After updating to the new MetaTrader 5 build 5403 with the Blend2D graphics engine, I noticed a strange issue when drawing text labels on the chart.

When my EA draws both a line and a text label at the same time, the line appears instantly in the correct position, but the text label first appears slightly off, then “jumps” into the correct place a moment later.

This did not happen before the update (GDI version). It seems to happen only with OBJ_TEXT , while OBJ_TREND works fine.

Here’s the part of my code that creates both objects:

if(!ObjectCreate(0, lineName, OBJ_TREND, 0, startTime, price, TimeCurrent(), price)) return;
ObjectSetInteger(0, lineName, OBJPROP_COLOR, lineColor);
ObjectSetInteger(0, lineName, OBJPROP_WIDTH, 1);
ObjectSetInteger(0, lineName, OBJPROP_STYLE, STYLE_SOLID);

if(!ObjectCreate(0, labelName, OBJ_TEXT, 0, startTime, price)) return;
ObjectSetString(0, labelName, OBJPROP_TEXT, displayText);
ObjectSetInteger(0, labelName, OBJPROP_COLOR, lineColor);
ObjectSetInteger(0, labelName, OBJPROP_ANCHOR, ANCHOR_LEFT_UPPER);

If you have to report a bug you need to provide a minimum source code that compiles to reproduce it. 

I can't reproduce it with what you posted.

 

I feel that I don’t like Blend2D because it seems to smooth out the graphics, making them appear a bit blurry and not very sharp. I’m using a 4K monitor, and I find it looks blurrier and less clear than the GDI version. Please zoom in and look closely at the image—sorry, I don’t have the skills to take a proper screenshot, so it’s a bit hard to distinguish compared to actual usage.

This issue occurs with every ObjectCreate OBJ_TEXT
 
I am on x64 build 5409. I'm unsure if this is a beta build or a specific version based on hardware. I am having issues with charting in the strategy tester specifically when using an event spy for multi-currency testing. Everything functions correctly in the terminal and in visual mode in the tester but for backtests no operations within OnChartEvent occur. I can see that some changes were made to fix duplicate events using EventChartCustom for this update and I believe thats the culprit. My EA's worked as intended before the update and nothing has been changed since.

Is anyone else having this issue?

If possible, please keep the GDI version as well, and during installation give me the option to install either the Blend2D version or the GDI version.

Apparently that has been fixed in build 5413 ...

Confirmed.

My live broker-dealer is still using Build 5370, while my MQ Beta Build is 5411 with another update pending. Therefore, Build 5409 looks like Beta to me.
