Users only need one subscription. Users can switch between subscription types or billing periods, annual or monthly, at any time. Existing subscriptions are prorated and discounted against the new subscription at the time of the switch. A video detailing the upgrade or switching process is here: {% embed url="" %} ### Additional notes Optional free trials are available on all tiers except Premium. [More information about the free trial can be found here](/welcome/free-trial.md). If a user is on the Premium tier and wants to downgrade to another tier, they should remove broker connections, pause opening new trades, and close existing trades first. The automation system will not manage trades without an active Premium subscription. Users with subscription questions can email `billing@optionomega.com`. ### Tier Comparison
