A Trade Leader only requires a Trade Leader plan to create a strategy on C2.
The price for each plan, plus its features, is listed on this page: https://trade.collective2.com/home/pricing/
The Trade Leader plan will automatically renew on a 30-day billing cycle charged to the credit card on file at C2.
Annual Trade Leader plans are also available if you want to take advantage of a 15% discount.
