Fig 1.2.1 illustrates the expiry price profile of an upbet. One of the features of binaries is that at expiry, bets have a discontinuous distribution, i.e. there is a gap between the winning and losing bet price. Bets don’t ‘almost’ win and settle at, say 99, but are ‘black and white’; they’ve either (except in the case of a ‘dead heat’) won or lost and settle at either 100 or zero respectively.

1. If the upbet is in-the-money, i.e. in the above example of Fig 1.1.1 the underlying is higher than $101, then the upbet has won and has a value of 100.

2. Alternatively if the upbet is out-of-the-money, i.e. the underlying is lower than $101, then the upbet has lost and therefore has a value of zero.

3. In the case of the underlying finishing exactly on the strike price of $101, i.e. the upbet is at-the-money, then the bet may settle at 0, 50 or 100 depending on the rules or contract specification.
