<summary>Internet connection</summary>

Level2 is a web based application so you will normally need to have an active internet at all times. The minimum internet connection speed we support is **2 Mbit/s**. But this is unsuitable if you work with large datasets and complex strategies. A fast internet connection will provide the smoothest experience and the most accurate trading conditions.

<summary>Browser recommendations</summary>

Google Chrome is the preferred browser. All other browsers are compatible but please keep in mind that some browser extensions and add-ons can interfere with Market Dynamics.

<summary>Performance issues</summary>

In the unlikely event that you experience slow performance or unexpected behavior when using Market Dynamics try the tricks below. If you have tried all the below and continue to experience performance issues, please contact technical support.

* **Empty your browser's cache** The process for clearing the cache varies, depending on which browser you use. Refer to the browser's support documentation for instructions.
* **Try using incognito mode or private mode**. In incognito mode, browser plug-ins do not run and plug-ins can sometimes interfere. If Market Dynamics works as expected in incognito mode, you can disable your plug-ins one at a time until you identify which one is causing the problem. You can then disable it when working in Market Dynamics in future.
