Trader A and Trader B now decide to trade a downbet with each other. Trader A is no longer feeling bullish and wishes to buy a downbet (Fig 1.6.1) and since Trader B has conveniently turned bullish, he sells it to him. This is not an aggressive trade that Trader A is putting on; since the strike price is $101 and the underlying is $100 therefore the downbet is already $1 in-the-money and has a better than an ‘evens money’ chance of winning. The price of his downbet has to reflect this probability and the price is agreed at 60, where they trade for $1/pt.
