comment Switching from Matlab to Python for Quant Trading and Research
I would just add few points on the matlab side: (1) if you buy the compiling toolkit, then you can redistribute your code everywhere without paying more license fees. (2) matlab statistical tools are very good and properly coded.

comment How to normalize different instruments by volatility?
@Freddy, please do not think that formalizing answers to try to be clear is academic arrogance. I try to be as concise as possible, we have the chance to share the formalism of stochastic calculus, I just use it.

comment How to normalize different instruments by volatility?
@Freddy, the question was about normalization and not volatility definition. your generic remark about "there is no single answer" should be on renormalization and not volatility, don't you think? your answer is out of the scope of the question I think.

@Freddy volatility of the price is the multiplier of the normalized random part of the returns. What do you call "returns volatility"?
