hey guys,
can anyone refresh our memories with the formula for the payoff, please? I remember that it is something involving the notional, some kind of risk factor and the difference between the strike spread and the spread @ expi, but would it be (strike -spread @ expi) or (spread @ expi- strike) from the LONG perspective?
I would go for the second, any idea?
Thanks,
M. |
