New MetaTrader 5 Build 5572: ONNX and Chart Rendering Improvements

New comment
 

The MetaTrader 5 platform update will be released on Friday, January 30, 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.

New MetaTrader 5 Build 5572: ONNX and Chart Rendering Improvements


MetaTrader 5 Client Terminal

  1. Terminal: Fixed text rendering on charts in macOS and Linux environments using Wine.
  2. Terminal: Corrected the drawing of indicators displayed as lines with variable colors.
  3. Terminal: Fixed rendering of Text Label and Button objects.
  4. Terminal: Corrected formatting of certain statistics in trading reports, which could previously round incorrectly.
  5. Terminal: Revised calculation of "Total Profit" and "Total Loss" in trading reports. These values now include commissions and swaps.
  6. Terminal: Fixed saving the toolbar state for undocked charts. Hidden toolbars could reappear after restarting the platform.
  7. Terminal: Fixed loading of custom trading instrument settings from JSON files. In particular, swap settings, trading sessions, and tick values could be imported incorrectly.
  8. Terminal: Added instrument and timeframe display in the window title when running a script on a chart.



    Added instrument and timeframe display in the window title when running a script on a chart.


  9. Terminal: Fixed duplication of trading instruments in the tooltip displayed when searching instruments in the Market Watch.
  10. Terminal: Fixed rendering of Wingdings fonts on charts.
  11. Terminal: Fixed rendering of indicators displayed as colored candlesticks (DRAW_COLOR_CANDLES) and colored lines (DRAW_COLOR_LINE).
  12. Terminal: Added output of a log message indicating that the broker's server is running an outdated version. If the server version is below 5200, released six months ago, a warning will be displayed:
    outdated server build - must be at least 5200, contact your broker please
    The message is displayed for informational purposes only and does not affect the ability to connect to the server.

  13. MQL5: ONNX library now loads on the first run of an MQL5 program that uses ONNX, rather than with the platform. Library updates occur automatically.
  14. MQL5: Added CUDA support for ONNX. If your graphics card supports this technology, model inference performance will be significantly improved. We strongly recommend updating NVIDIA drivers to improve stability and performance.
    CUDA usage permissions can be managed in the platform settings:

  15. MQL5: Updated flags in the ENUM_ONNX_FLAGS enumeration. These flags are used when creating and executing ONNX models:

    Logging
    Instead of the deprecated ONNX_DEBUG_LOGS, the following logging flags are now used:

    • ONNX_LOGLEVEL_VERBOSE — log all messages.
    • ONNX_LOGLEVEL_INFO — log informational messages, warnings, and errors. Replaces the deprecated ONNX_DEBUG_LOGS.
    • ONNX_LOGLEVEL_WARNING — log warnings and errors. Used by default.
    • ONNX_LOGLEVEL_ERROR — log errors only.

    CUDA and GPU Management
    The ONNX_CUDA_DISABLE flag has been removed. Use the new ONNX_USE_CPU_ONLY flag instead. When enabled, only the CPU will be used for model execution.

    Flags have been added to select the GPU device on which the model will be executed:

    • ONNX_GPU_DEVICE_0
    • ONNX_GPU_DEVICE_1
    • ONNX_GPU_DEVICE_2
    • ONNX_GPU_DEVICE_3
    • ONNX_GPU_DEVICE_4
    • ONNX_GPU_DEVICE_5
    • ONNX_GPU_DEVICE_6
    • ONNX_GPU_DEVICE_7

    Use these flags if the system has two or more CUDA-capable devices. If multiple flags are specified, the device with the lowest index will be selected.

    Model Profiling
    We've added the ONNX_ENABLE_PROFILING flag to enable ONNX model profiling.

    When a model is started with this flag enabled, a profiling report file with the name: [EX5 file name]_[date]_[time].json will be created in the /MQL5/Files/OnnxProfileReports/ folder.

  16. MQL5: Increased the limit for files that can be included in a program as a resource. The new limit is 1 GB, allowing you to include large ONNX models in projects. 
  17. MQL5: Improved stability for OpenCL operations.
  18. MQL5: Added ReplaceToZero method. It replaces small values in a matrix/vector with zero values and returns the number of replaced elements.
  19. MQL5: Added new OpenBLAS methods:

    • FactorizationLDLComplexSyRaw — computes the factorization of a complex matrix using the Bunch-Kaufman diagonal pivoting method.
    • LDLComplexSyLinearEquationsSolution — solves a system of linear equations A * X = B with a complex symmetric indefinite matrix using the factorization A = U**T * D * U or A = L * D * L**T computed by FactorizationLDLComplexSyRaw, with multiple right-hand sides.
    • LDLComplexSyInverse — computes the inverse of a complex symmetric indefinite matrix using the factorization A = U**T * D * U or A = L * D * L**T computed by FactorizationLDLComplexSyRaw.
    • LDLComplexSyCondNumReciprocal — estimates the reciprocal of the condition number of a real symmetric or complex Hermitian indefinite matrix A, using the LDLT factorization computed by FactorizationLDLRaw.

  20. MQL5: Added the ColorToPRGB function. It converts the color type to uint to get a PRGB color representation. This format is used when creating graphic resources, rendering text, and in the standard library CCanvas class when working with the COLOR_FORMAT_ARGB_RAW color format. 
    uint  ColorToPRGB(
   color  clr,          // the color to be converted, in 'color' format
   uchar  alpha=255     // the alpha channel that controls color transparency
);
    The PRGB color is calculated using the following formula:
    R = R * A / 255
    G = G * A / 255
    B = B * A / 255
    A = A
  21. MQL5: Fixed programmatic text setting for OBJ_LABEL, OBJ_TEXT, OBJ_BUTTON, and OBJ_EDIT objects. The text might not be displayed under certain conditions.
  22. MQL5: Fixed setting colors for graphical objects using ObjectSetInteger. The value clrNONE could previously be ignored.
  23. MQL5: Fixed Bars function freezing when no price history is available on the server.
  24. MQL5: Fixed global variable search in scopes. Previously, variables inside a namespace could not have the same names as global-level variables.
  25. MQL5: Fixed operation of the final attribute. Attempting to override a function marked as 'final' now correctly produces a compiler error.
  26. MQL5: Fixed false compiler warnings that occurred when using function forward declarations in included *.mqh files without the #import directive. The compiler now correctly handles such declarations and does not require #import if the functions are not imported from a DLL.

    Example

    File utils.mqh: 
    // Function forward declaration
double CalcLot(double risk, double stop);
    File expert.mq5: 
    #include "utils.mqh"

double CalcLot(double risk, double stop)
  {   
   return risk / stop;
  }
    Previously, the compiler could issue a warning that the CalcLot function in utils.mqh was missing the #import directive, even though the function is user-defined and implemented in the project code. Such code now compiles without warnings. The #import directive is required only for functions actually imported from external DLLs. 

  27. MetaEditor: Fixed out-of-memory errors when working with large source files (megabytes).
  28. MetaEditor: Fixed display of enumeration values and names in the Watch window during debugging.
  29. Tester: Fixed termination of testing for looping Experts Advisors. Even with infinite loops, pressing "Stop" now halts execution immediately.
  30. Tester: Fixed EventChartCustom call during visual testing. Previously, the event could be mistakenly sent twice.
  31. Tester: Corrected freeze level check (SYMBOL_TRADE_FREEZE_LEVEL) when deleting newly placed pending orders.
  32. Tester: Fixed export of forward-testing data. When exporting a test that did not use forward mode, data from previous forward tests could sometimes be saved.
  33. Updated user interface translations.

MetaTrader 5 Web Terminal

  1. Added display of approximate profit/loss in money when setting Stop Loss or Take Profit on the chart.

  2. Fixed display of symbol specifications for instruments with special characters.
  3. Corrected display of negative prices in trade dialogs.
  4. Fixed display of account financial metrics for cases where the deposit currency has precision greater than two decimal places.


The update will be delivered via Live Update.

 
Great to see MT5 evolve into a better version 
 
great, can't wait for the beta version to be release
 
Yes it is awesome to be launch. 
 

Please @MetaQuotes, make the remaining timeframes available in the web terminal.

Pleasr Keep Crosshair Visible, no hide After Mouse Click on Chart (Hide Only via Ctrl+F or  click button Toolbar)


Hello MetaQuotes team,

I would like to suggest an improvement regarding the default Crosshair tool behavior in MetaTrader 5.

Currently, when the Crosshair is enabled using the toolbar button or the Ctrl + F hotkey, it is automatically hidden as soon as the user clicks on the chart. This behavior makes the Crosshair work only as a temporary tool and interrupts the analysis workflow.

For many traders, the Crosshair is not only a measuring tool but also a continuous visual reference for price and time alignment during chart analysis. Having it disappear immediately after a mouse click forces users to repeatedly re-enable the Crosshair, which is inconvenient and inefficient.

I would like to request that the Crosshair remain visible after clicking on the chart, and only be hidden when the user explicitly disables it by clicking the Crosshair toolbar button again or pressing Ctrl + F again.

If changing the default behavior is not desirable, please consider adding a terminal setting option such as “Keep Crosshair visible after mouse click”, or providing an API or configuration flag to control Crosshair persistence.

This would be a small user experience improvement but would significantly enhance chart analysis efficiency for many users.

Thank you for your time and consideration.

Best regards.

I’ve implemented a custom crosshair indicator tailored to my requirements, however, it still doesn’t match the smoothness and responsiveness of MT5’s built-in crosshair. Although the latency is minimal, there is still a slight but noticeable delay.

Thank you for your support.

Nevertheless, I sincerely hope that MT5 will consider implementing this idea of mine.

 
Great update! One issue I noticed is that it looks like ChartTimePriceToXY now takes 100x CPU cycles than before.
 
آندری مورارو # : به‌روزرسانی عالی! یک مشکلی که متوجه شدم این است که به نظر می‌رسد ChartTimePriceToXY تقریباً برابر با چرخه‌های CPU نسبت به مصرف قبل از مصرف می‌کند.
It's true, I have this problem too, and MetaTrader locks up and all CPU cores are involved, to the point that I had to go back to version 5430. This is a really strange problem. This has never happened before.
