I have trouble understanding how those options are priced. To be more specific, I'll give an example. I buy the following option: PUT EUR/USD (Buy USD, Sell EUR) Strike Price: 1.10 Expiry Date: 01 MARCH 2016 Price: $0.02625 Contract Size: EUR 100,000 Actually, if I input price 0.02625 and quantity 1 to my online broker, it presents me as final price: $2.625, so I suppose that I buy 100 contracts (and therefore I have the right to buy 11,000,000 USD for 10,000,000 euros) Now suppose that on 01 March 2016, the current rate is 1.05 USD for 1 EUR. According to the data above, how much should my profit be? I would expect it to be: USD 500,000 from the formula: (100 contracts)*[(100,000 EUR)*(1.10 USD)-(100,000 EUR)*(1.05 USD)] On the other hand, it's impossible to make such a profit with a $2 investment, so what have I understood wrong about those options?

I don't know much about FX options, but I'd say that the multiplier should be 100,000. Those options may cost $2625 each. The 100 contract trade would cost 262,500.
