Tips & Best Practices

Tip Keep your payment method up to date to avoid service interruptions — failed renewals will suspend access to premium features within 24 hours
Tip Review the proration preview before upgrading mid-cycle to understand the exact amount you will be charged for the remainder of the billing period
Tip Monitor your Credits usage weekly to avoid unexpected depletion, especially when running multiple AI-powered backtests or code generation tasks

Frequently Asked Questions

What happens when my subscription expires?
When your subscription expires, premium features such as AI model access, advanced backtesting, and code generation become unavailable. Your saved strategies and historical data are preserved and will be accessible again once you resubscribe.
How does proration work when upgrading mid-cycle?
When you upgrade your plan mid-billing-cycle, Stripe calculates the prorated difference between your current plan and the new plan for the remaining days. You only pay the difference, and the new plan takes effect immediately.
What is the 7-Day Risk-Free Guarantee?
New subscribers are eligible for a full refund within the first 7 days if they have used less than 15% of their first-month credits quota. This guarantee applies once per account and is processed automatically upon request.
Can I update my payment method while my subscription is active?
Yes, you can update your payment method at any time while your subscription is active and set to auto-renew. Click the 'Update Payment Method' button to open the secure Stripe portal where you can add a new card.

Important Notes

Warning Subscription payments are processed automatically through Stripe. Ensure sufficient funds are available to prevent service interruption. Contact support if you experience billing discrepancies or need assistance with refund requests.
