US vs European Options Markets
"American vs European" describes when an option can be exercised; "US vs European" is a different question — where the option is listed and traded. For a European investor that second question decides the currency, the settlement, the trading hours and how easily you can actually trade it. Here is how the two markets compare.

Two different questions: style vs market
It is easy to confuse two distinctions that share the same words. American-style vs European-style is about exercise timing — any time versus only at expiration — and depends on the underlying, not the country. US-listed vs European-listed is about the market: which exchange the contract trades on, in what currency, and under whose rules. A US-listed and a European-listed option on the "same" company can differ on almost every practical axis.
This guide is about that second question. It matters because most online options tools — including this one — price US-listed options, while a European trader may also have access to euro-denominated contracts on Eurex or Euronext that behave quite differently.
The US options market
US-listed options trade on US exchanges and are cleared by the OCC, which all but removes counterparty risk. They are overwhelmingly American-style on single stocks and ETFs, quoted in US dollars, and extraordinarily liquid — tight spreads, weekly and even daily expirations, and a vast choice of strikes. That depth is why US options dominate online education and tools.
Crucially for Europeans, many familiar European companies also trade as US-listed options through their US listing — ASML on Nasdaq, Shell, Novo Nordisk, SAP and others — in dollars. Those chains are deep and are exactly what the OptionProfit calculator prices. The trade-off is USD exposure and US trading hours.
European-listed options (Eurex and Euronext)
Europe’s own options trade mainly on Eurex (Euro Stoxx 50, DAX/ODAX and single names) and Euronext (the AEX in Amsterdam, the CAC 40 in Paris, the BEL 20 in Brussels). They are euro-denominated and trade in European hours. The big index options are European-style and cash-settled — no early assignment, and the payoff is settled in cash rather than delivering the index.
The practical catches: retail liquidity is generally thinner than in the US, and you need a broker that offers these markets (Lynx / Interactive Brokers, DEGIRO, Saxo). Live euro option chains are also not freely redistributable the way US data is, so few free tools display them — which is why this site prices the US-listed versions and treats euro/Euronext options as something you trade through your broker.
- "American vs European" is exercise style; "US vs European" is where the option is listed and traded — different questions.
- US-listed options: USD, mostly American-style, OCC-cleared, extremely liquid, US hours — what most tools (including this one) price.
- European-listed options: euro-denominated on Eurex/Euronext, the big index options are European-style and cash-settled, European hours, thinner retail liquidity.
- Many European companies (ASML, Shell, Novo Nordisk, SAP) also trade as liquid US-listed options — euro-name exposure in dollars.
Frequently asked questions
What is the difference between US and European options?
It depends which difference you mean. "American vs European" is about when you can exercise (any time versus only at expiration). "US-listed vs European-listed" is about the market — US-listed options trade in dollars on OCC-cleared US exchanges, while European-listed options trade in euros on Eurex and Euronext, often European-style and cash-settled.
Can a European investor trade US options?
Yes — most European brokers offer US-listed options. You take on USD exposure and trade during US hours, but you get far deeper liquidity and weekly expirations. Many European companies (ASML, Shell, Novo Nordisk, SAP) are themselves available as US-listed options.
Why do most options tools only show US options?
Because US options data (OPRA) is widely and cheaply licensed for redistribution, while Eurex and Euronext license their data more restrictively. Free tools — including this one — therefore price US-listed options and leave euro/Euronext options to your broker’s platform.
