comment where can i get data for foreign exchange order flow
The foreign exchange market is decentralized. There's no one place you can go to get the total order flow. You could get order flow for foreign exchange futures though.

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.

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.

Fill-or-kill orders aren't displayed in the limit order book. They're immediately matched, or canceled.

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.
