Where are open-end funds traded?
Close-end funds just means there's a fixed number of shares available, so if you want to buy some you must purchase from other existing owners, typically through an exchange. Open-end funds mean the company providing the shares is still selling them, so you can buy them directly from the company.  Some can also be traded on exchanges as well.
