Error 'Application is already running'

  • This message is displayed if you try running multiple Quantowers in parallel on the same computer or you have closed Quantower a few seconds ago and it did not finish closing yet. In 20 seconds or sooner Quantower can be started again.
  • If even after a few minutes the platform fails to start, go to the Task Manager. Press Ctrl+Shift+Esc to open the Task Manager with a keyboard shortcut or right-click the Windows taskbar and select “Task Manager.” Find the process with the name "Starter", select it and click on End task.

An error occurred during platform initialization: Exception has been thrown by the target of an invocation

  • This issue may occur if you're running the platform on older versions of Windows. The platform is compatible only with Windows 10 and 11. For complete system requirements, please refer to the provided link in our knowledge base.
  • This error occurs due to the removal of the file by the Avast antivirus or AVG antivirus, which is necessary for the correct work of the platform.
Our developers informed Avast and AVG companies that the file CefSharp.BrowserSubprocess.exe is a part of the CefSharp library — HTML5, JavaScript and PDF supported Web browser based on Chromium Embedded Framework. It allows using web browsing services in applications to create the user interface. We use this library in our platform as well. More information about it can be read here https://cefsharp.github.io
We don't know a reason why antivirus sometimes recognizes this file as suspicious, but if you search in Google, you can see that there are already many reports from users about the same problem: https://www.google.com/search?q=cefsharp.browsersubprocess.exe+antivirus In general case antivirus developers recommend reporting a problem as false positive.
To be 100% sure, that this file is not dangerous, you can check it manually using different web services like https://www.virustotal.com They will display your results received from different antiviruses.
CefSharp.BrowserSubprocess.exe is checked by all major antiviruses
As a solution, we recommend you remove Avast or AVG antiviruses (completely) and reinstall the platform.
Sometimes Kaspersky deletes our files.

An error occurred during platform initialization: Object reference not set to an instance of an object

Trendlines are moving on tick charts. How to resolve it?

Currently, there is an issue with the independent movement of drawings (trendlines, rectangles, etc.) on non-time-based chart types such as Tick, Range bars, Volume bars, and Renko.
To prevent changes in drawings, we recommend placing the endpoint of the drawing before the current (forming) bar. Additionally, we suggest enabling the 'Right Ray' option in the settings of the respective drawing.

Data latency (xxx ms) on Chart, DOM Trader

This message appears when there's a delay in data within a specific time interval. The cause may stem from a slow Internet connection or issues on the data provider's end.
Whether the data delay occurs on a Rithmic server, CQG, Binance, or during transmission to the client, we make efforts to identify instances where server-side timestamps start to lag.
Additionally, you have the option to mitigate data load by closing panels, disabling volume tools, or closing unnecessary tabs in your browser (if it's active while using the platform).

Chart Flickering Issue

Users may sometimes experience chart flickering on their PCs while using the platform. This issue is often related to the graphics card and its use in rendering the interface.
  1. 1.
    We recommend updating your graphics card drivers.
  2. 2.
    If there are no driver updates available for your card, the platform offers a 'Use Software Render Mode' setting. This disables the use of the graphics card and switches to software rendering, which may resolve the flickering.
  3. 3.
    Regularly check for Windows updates and driver updates. If the issue resolves after updates, you may disable 'Use Software Render Mode' for better platform performance.
