What is OTC trading?
OTC stands for over-the-counter, and refers to a trade that is not made on a formal exchange. Instead, most OTC trades will take place directly between two parties — often two traders, or a retail trader and a provider. Many OTC trades are handled via a dealer network.
When you trade OTC with a trading provider, you'll usually see two prices listed: a single buy price, and a single sell price. This differs from on-exchange trading, where you'll see multiple buy and sell prices from lots of different parties.
