If the variant, target, and goals for an experiment are defined you can start an experiment ahead of its scheduled start date and time by clicking the Start button in the header panel on the experiment configuration screen. This gives you the option to either start the experiment immediately and sets the end date 28 days from the time that the experiment started, or to define a schedule for the experiment. Please refer to the Configure the schedule section of this document for more information.

To stop an experiment that is currently in progress, click on the Stop button for the experiment on the In Progress Experiments page or on the experiment configuration screen. This stops the experiment with immediate effect, updates the end date and time for the experiment and moves the experiment to the Completed panel on the Experiments dashboard.

You can also stop an experiment that is currently in progress by clicking on the Stop button in the experiment configuration panel Detailed Results screen for the experiment.
