In this article we show a simple but important relationship between
the put-call transformation and the put-call symmetry as well as extend
the relationship to also hold for single and double barrier options. These
new barrier transformations give new insight in barrier option valuation.
Using the transformation it is possible to value a barrier put option from
a barrier call option formula and vice versa. Our results also extend the
possibilities for static hedging and closed form valuation for many new
exotic options. The new relationships also make us able to value a double
barrier option in a simple and intuitive way, only using a few single barrier
options.
