If we denote by S the FOR/DOM exchange rate (i.e., 1 unit of foreign currency is worth S units of domestic currency) we can observe that paying out 1 unit of the domestic currency if the spot at maturity is above or below the strike is exactly like a cash-or nothing call and put respectively. Similarly, paying out 1 unit of the foreign currency if the spot at maturity is above or below the strike is exactly like an asset-or nothing call and put respectively. Hence if we now take {\displaystyle r_{\mathrm {FOR} }} , the foreign interest rate, {\displaystyle r_{DOM}} , the domestic interest rate, and the rest as above, we get the following results.
Your analysis indicates the S&P 500 will rally for the rest of the trading day and you to buy an index call option. It's currently trading at 1,800 so you're wagering the index's price at expiration will be above that number. Since binary options are available for many time frames – from minutes to months away – you choose an expiration time or date that supports your analysis. You choose an option that expires in 30 minutes, paying out 70% plus your original stake if the S&P 500 is above 1,800 at that time or you lose the entire stake if the S&P 500 is below 1,800. Minimum and maximum investments vary from broker to broker.
