    Using the Black – Scholes model, i ended up with a negative number for n(d2).

    When doing the final computation for ‘C’, how should i treat this negative n(d2)?

    You cannot end up with a negative number for N(d2). You can end up with a negative d2 and in this case you subtract the number from the tables from 0.5.

    I do explain this in my free lectures on option pricing.
