Yes, you can control the amount of quota an experiment consumes. Customers holding a Professional subscription to Nelio A/B Testing can indicate the maximum number of PageViews that an experiment can spend when running. Just go to the Advanced tab in Settings and modify the option Quota Limit. Then each experiment will be automatically stopped once surpasses the amount of Page Views indicated.
In addition to it, customers holding an Enterprise subscription to Nelio A/B Testing can modify this behavior when creating an experiment. They just need to indicate that the Finalization Mode of the experiment will depend on the number of page views, and then select the maximum amount of page views allowed to be spent by that experiment.
