One issuer of binaries may stipulate that there are only two alternatives, a winning bet whereby the underlying has to finish above $101, or a losing bet whereby the underlying finishes below or exactly on $101. A second company might issue exactly the same binary but with the contract specification that if the underlying finishes exactly on the strike then the bet wins. A third company may consider that the underlying finishing exactly on the strike is a special case and call it a ‘draw’, ‘tie’ or ‘dead heat’, whereby the upbet will settle at 50. This company’s rules therefore allow three possible upbet settlement prices at the expiry of the bet.

N.B. Throughout the examples in this book the latter approach will be adopted whereby in the event that a bet is a ‘dead heat’, or in other words, where the underlying is exactly on the strike price at expiry, then it is settled at 50.
