You're missing some cases though...

@MarcoBreitig It's true that the conclusion is not very clear, but I've seen much worse here.

comment How to price exotic options using Monte-Carlo?
It is claimed that... where did you see that? because I'm not sure what you mean by using log values. Plus, what are you looking for exactly? Implementation of Monte-Carlo methods for geometric Asian and discrete barrier options? Or some example relating to your claim?

Why would bank deposits be more tradable than S&P futures? You mean cash?

We usually group all data in this question, but this specific request is interesting and quite uncommon so I'll leave it open see what the community thinks

comment How to assess stock price movement from implied volatility?
@Richard yeah I mean he has to estimate $\mu$ historically or get it somewhere obviously...

comment How to assess stock price movement from implied volatility?
I'm not sure I understand the "trick". One important thing though: the answer is only correct if the expected return of the stock is $\mu=0$, other wise he needs to add $\mu$ to +/- his result.

It's the last time I let you post question with bad formatting. I already asked you nicely to pay attention in your last question. Next one like this will result in a ban.

What is the assume correlation between $B_\mu$ and $B_x$?

Also, it would be interesting to see where you got this model from (or did you come up with it)? Didn't this source provide any clues on how to calibrate? What have you tried so far?
