comment What is a martingale?
"you can think that all information is in the current price, I think this more comparable to Markov Property" -- I think rather that EMH is saying that the price is an adapted process -- Markov or not.

comment What is a Quant
I would change "develops" to "develops, implements, tests and maintains". Otherwise, I think it's the best definition. Short and to the point.

comment What is the implied volatility skew?
"It shows that OTM puts (high demand) are usually have higher price (for the same expiry) than OTM calls (high supply to buy protective puts)." -- this is incorrect both factually and grammatically.

Please correct the spelling error in the question (it's "martingale" not "martinglane").

comment How to show that this weak scheme is a cubature scheme?
You may try asking this question on mathoverflow.net, it seems to be math-heavy enough.
