adding that usually, when
models go wrong, one identifies a couple
of the largest deviations between reality and the
model, and proceeds to find
out why the
heck were they wrong.
In addition, there's a whole mathematical side
of options trading that completely confuses the
heck out of me (like how the Black and Scholes
model works), and I don't claim to understand the extremely complicated equations that explain option decay, option price movement, and so forth.
