Exchange vs. over-the-counter (OTC)

You can tell whether a trade happens on an exchange or over the counter and explain what that means for prices and risk.

Not every trade meets an exchange

The last lesson followed an order to an exchange. But a large share of all trading never goes near one. It happens directly between two parties, by phone, over a dealer's platform or inside a trading app.

That is called trading over the counter, or OTC. Many popular products for private traders work this way, often without the trader knowing. And it changes two important things: who sets the price, and who you are relying on if something goes wrong.

Two ways to trade

On an exchange, orders from many participants meet in one central order book. Prices are public, every trade is reported, the products are standardized, and a clearing house stands between buyer and seller.

Over the counter, two parties trade directly with each other. Usually a dealer quotes two prices, one at which it buys and one at which it sells, and you trade at one of them. The other party in your trade is your counterparty.

This has consequences:

Prices are less transparent. There is no central order book. You see the dealer's quote, not the whole market. The SEC warns that in retail forex, dealers act for their own account and may not offer the best price available.
Counterparty risk. Without a clearing house, you depend on the other side being able and willing to pay.
Flexible products. OTC contracts can be tailored, which is why large companies use them to hedge. For private traders, the offer is usually set by the provider.

For private traders, the most common OTC products are spot forex, CFDs and many crypto offers on trading platforms. Some shares also trade OTC, especially those of small companies that are not listed on an exchange, often with little information and thin trading.

Two trades, two structures

A share on an exchange. You buy 20 shares of a fictional company at 50.02. The price came from the order book, where many buyers and sellers compete. After the trade, the clearing house settles it.
Euro against dollar with a broker. Your app shows EUR/USD at 1.0850 to sell and 1.0852 to buy. These are the broker's own prices. You buy at 1.0852, and the broker, or a firm it works with, is on the other side of your trade. When you close, you sell back to the same provider.

In the second case there is no public order book to compare with and no clearing house. The quote is still often close to the wider market, but you rely on the provider for both the price and the payout.

Common mistakes

"OTC means shady." Huge parts of the currency and bond markets trade OTC between banks every day. OTC is a structure, not a warning sign.
"The price is the same everywhere." OTC quotes differ between providers, especially when markets move fast.
"A crypto exchange is like a stock exchange." Many crypto platforms act as broker, exchange and custodian at once, often with fewer protections than a regulated stock exchange.
"Counterparty risk is only for big banks." If your provider gets into trouble, it is your money that is at stake.

The takeaway

On an exchange you trade with the market, through a clearing house. Over the counter you trade with someone. Always know who is on the other side of your trade.

Quick quiz

4 questions. Instant feedback, nothing is saved.

1In an over-the-counter trade, who is on the other side?

OTC means two parties trade directly. For retail traders the other side is usually the dealer or provider.
2Tap your counterparty in an OTC trade.

Tap the chart.

The dealer or provider is your counterparty. If it fails, there is no clearing house in between.
3Which of these is usually traded over the counter for retail traders?

Retail forex is typically traded with a dealer, not on an exchange. Shares on Xetra and exchange futures are traded on exchanges.
4Why can OTC prices be harder to judge?

Without a central order book, you see the dealer's quote, not the whole market. Comparing quotes is harder.
