There are 2 types of fees for AutoTrading:
1) Strategy Subscriptions - Each strategy has it's own monthly subscription price.
2) AutoTrading Plan - Select the plan that supports how many strategies you will be AutoTrading. You can upgrade your plan any time. Discounted annual plans are available. For more details, click here Collective2 Pricing Information (click "Look here" for Investors).
Each C2-related fee will automatically renew on a 30-day billing cycle charged to the credit card on file at C2.
All C2 Subscriptions and plans can be managed from here: Subscription & Plans Management
You can subscribe to a strategy only (no AutoTrade Plan) if you plan on just manual trading.
