Yes. You can upgrade or downgrade your Social Trader Tools subscription at any time.
When you upgrade your account hosting package, the additional cost is charged on a pro-rata basis for the remainder of your current billing period. Your new package price will then apply from your next renewal date.
If you downgrade your subscription, the unused portion of your current plan is applied as account credit toward your next payment.
This flexibility allows you to increase or reduce your account hosting capacity as your trading requirements change, without being locked into a long-term contract.
