They might not get the best price, but they get the price they are willing to sell (or buy) at. If you don't want to sell your stock at $10, then don't. Nobody is forcing you to.
It might seem odd to us, but the reason that high-frequency trading works is because to someone, somewhere thinks that it is better to buy XYZ at $10 now rather than $9.99 at some unknown time in the future.
I am a UK resident, and I didn't say it was a "charming little English shoppe".
In London I've used both big chain food shops and individually owned ones. The big chain ones are always better in my experience.
There is a "charming little English shoppe" place in the West End that I was in recently. It was expensive, crowded, and had really crap service.
Just across the road from the Earl's Court Tardis is a lovely bakery, the Bakers Oven. As well as doing great food, they also accept any UK banknotes, which I find handy - when I stay in London I stay round there, and I usually have Northern Irish notes on me, which are difficult to get people to accept outside Northern Ireland.
I would turn down an applicant if they HADN'T drunk at least one beer at college. Seriously - would you really want someone on your team that was obviously so self righteous and prissy as to never have cut loose a bit at one time or another?
I don't drink, mainly because I don't like it. I do cut loose in other ways though.
I spend a lot of time at the gym doing bench presses and the like. There are very few real-world applications of that skill. Today I was moving furnature, which was made easier by the fact that I can bench press my own body weight.
Calculus has the same relationship with programming as bench-pressing does with furnature moving. If you are good at one, then it will help with the other, and if you suck at one then there is a good chance you suck at the other.
Persistence is a good thing in the workplace; one of the main things that a degree demonstrates is that someone has had the persistence to get it finished. A degree is not just a piece of paper. It is evidence of hard work.
I follow a lot of people on Twitter that couldn't follow an RSS feed, let alone set one up.
Twitter is just asynchronous IRC with a few conventions like @reply and #hashtag.
Suppose I want to buy a book. I can either go to the publisher of the book, or go to a bookshop.
If I deal directly with the publisher, I might be able to get a discount, compared to the price I pay at the bookshop.
But I personally find it easier to deal with the bookshop. It might be more expensive, but it is more convenient. I pay a premium for that convenience.
If I put a widget on the market for $1, that is what I think the fair value is. If someone buys it from me at that price, I still get a fair deal. If he goes on to sell it for $2, that isn't money I have lost, and if I have "lost" it, it is only because I made the wrong decision. I should have set the price higher.
Now, maybe if I set the price higher, it would have taken longer to get the sale. But in this case I have clearly decided that $1 per widget now is worth more to me than $2 per widget later.
High frequency trading is based on exploiting knowledge that isn't available to everyone.
No it isn't. Once the data is published on the data feed, it is available to everyone who buys that data. Just because a computer can make decisions faster than someone waiting for their evening copy of the FT doesn't mean the computer has access to data the guy waiting for his paper doesn't.
a high frequency trading program will see these orders getting ready to be placed
No it doesn't. A high-frequency trading program sees the orders being placed at the same time as everyone else. It doesn't see them getting ready.
A lot of the market data feeds are sent out on multicast, specifically to avoid one subscriber getting it "first"
Not all subscribers need the data to be so fresh. I guess (but don't know) that some data feeds are available at different prices, a low-latency price and a not so low-latency price. It would make sense. Market segmentation et cetera.
Yup. The latency for some feed handlers that NYSE Technologies produces can be as low as 10-20 microseconds. Or even nanoseconds for transport latency. The feed handler is the software that takes the input form the data feed and converts it to something the trading apps can use.
Its a lot of work to get software to go that fast, and it wouldn't be done unless it was worth it.
Disclaimer: I work for NYSE Technologies. Actually, I'm the manager of the tech pubs team, and before I left the office today I was writing a manual about this stuff.
"Ireland" is the island. The Republic of Ireland is the country in the south. Northern Ireland is the bit in the north. I've lived in East Belfast all my life, except when I was a student, and I don't know anyone who would say that Northern Ireland isn't in Ireland.
If I was writing professionally and this came up I'd use the terms "Republic of Ireland" and "United Kingdom" to describe the two countries in the British Isles. The only time I'd use "Ireland" is when I mean the island. "Ireland" as short for "Republic of Ireland" is confusing (and arguably offensive in some cases).
Don't tar all religious people with the same brush. I'm religious (I self-label as liberal Christian) and I don't mind[1] when people blaspheme Christianity
[1] In the sense that although I disagree with them, I don't think I need to take any action to prevent them from expressing their opinion.

Just citizens? Why not when they beat-up anybody?

The same could be said about radiotherapy. It is when it is used by people who don't know what they are doing that the problems arise.

Abortion is illegal in Northern Ireland, "except in limited circumstances where the mother's life or mental well being are considered at risk". It is one of those unusual things where there is cross-party agreement.
FWIW, I'm in Ireland and the UK right now.
