Trader B’s three possible outcomes are:

1. Trader B has sold 40s and therefore wants to see the underlying below $101 where the upbet is worth zero at expiry and Trader B collects the premium of 40 ¥ $1 = $40.

2. If the upbet settles at-the-money the upbet is worth 50 and Trader B loses $10 having gone ‘short’ $1/pt at 40.

3. The underlying is above $101 at the upbet’s expiry so Trader B loses outright to the tune of $60.
