My formal education is in economics. My programming skills and computer knowledge are self-taught. I have an uncanny ability to find answers to questions outside my immediate expertise. I have a deep love of learning and I enjoy building / fixing all kinds of things -- software, computer hardware, engines, etc.

It's a flow, not a stock; like the difference between income and wealth.

comment Microstructure effects for a market maker?
@statquant: of course you have something valuable to share. You're here because you do this for a living. So you could ask a question where the answer would be directly related to how you make money. Then you answer your own question, providing details on what gives you an edge over other market participants.

comment Microstructure effects for a market maker?
@statquant: That's rather hypocritical coming from someone who has yet to share valuable information themselves.

comment Microstructure effects for a market maker?
This is not a discussion forum. Questions asking for a "lists of things" are not a good fit for the Q&A format of this site.

comment Are proof-of-work systems used by exchanges?
Connections to exchanges aren't public. The exchange knows who is sending the requests, even if they don't publicize it. Many exchanges (e.g. US futures) have messaging limits and penalize you if you violate them.

comment Where do these Orders come from and what do they mean?
Fill-or-kill orders aren't displayed in the limit order book. They're immediately matched, or canceled.

comment Downside deviation
I'm sure many have worked with it. It's utility depends on what you need to do. Yes, it can help with risk management.

comment Where do these Orders come from and what do they mean?
This question appears to be off-topic because it is about the rules of a specific exchange, not mathematical/computation finance.

comment Normality assumption in Sharpe ratio
@MattWolf: so you would argue that there's no normality assumption? Even if you account for upside/downside deviation, the Sharpe Ratio still has issues if the distributions are non-normal.

comment Normality assumption in Sharpe ratio
This is a basic statistics question. The Sharpe ratio is calculated using the mean and variance of a distribution, therefore it is a less descriptive measure the more the mean and variance do not completely describe the distribution.

comment What R-packages for SOCP problems are there?
There's at least one in the Optimization Task View. You can probably find more by searching via rseek. I'm not sure if it's the same here, but questions asking to recommend or find a tool, library or favorite off-site resource are off-topic on StackOverflow.
