I guess I am trying to say (clumsily, perhaps) that you need to be aware of other instruments and their pricing. It's not necessarely YOUR hedging; you should consider MY position as well.Say you offer my a forward deal OTC where the underlying is currently at x and the rf interest rate is r, then you will need to be aware of the synthetic positions out there if there is a functioning options market - otherwise I just buy all you have if you are offering the forward at <<100exp(rT); ceteris paribus, MY hedge would be to buy a put and sell a call and arbitrage you ... no matter what your quant/strat arb model is saying, you are leaking money in the long run!silly example but can't be bothered making up a proper one.Alk
