Are you a sales rep for MS ? This is a truely stupid and untrue assertion. Should we mention all the server side Java development that is going on, or the massive number of web sites built with PHP, Perl, Python, all the open source development happening in C/C++ and countless other examples...

Symbol is $NYSI

Why don't you use one of the third party applications eg QT, Button trader et etc. TWS doesn't limit the number of applications that simulaneously connect using the API. Ask the vendors about it.

Sorry, didn't really answer the question. Yes, virtualization means one host and multiple guest OS running at the same time each in their own virtual machine. Therefore multiple Linux kernels.

Some options for true virtualization under Linux - 1. vmware 2. Xen Probably running a browser under a separate user id is pretty safe. Maybe in a chroot(2) jail - not sure I haven't tried it. When the new CPUs come out Xen will probably support Windows and other OS as well as Linux. Free.

Maybe the exported data file lines are terminated with '\n' (Unix style) rather than \r\n (DOS/Widows style) and TS chokes on them. Find a unix to DOS text file converter and try that. Also check if mysql has an option to export DOS format.

It seems to me that if one desires a high level of protection against security exploits triggered via browser access then the only real protection is to run your browser in a 'sand box'. These types of vulnerabilities will continue to pop up in the future and PCs running browsers will continue...

I have found it to be very reliable but i have written my own downloader. In fact I've found the service to be near to 100% reliable. Mokwit is right about two simulaneous requests either from separate applications or from the same application. TWS does return an appropriate error via the API so...

It might seem a bit paranoid, but I don't think it's a very good idea to install these sort of trinkets on a trading computer. How do you really know it doesn't contain some sort of malware such as a keylogger listening for logins to fx brokers ?

It would depend on the mix of jobs running on the machine and what type of jobs etc. System performance is a complex topic and fiddling with this sort ot thing is probably not a good idea unless you know what you are doing. If you think pageing is slowing down your machine, why not take by far...

And for Globex FX futures via IB data feed:

Here are some live bid/ask spreads from IB IDEAL PRO

QCharts and QCollector. I wasn't much impressed with either, but is probably the cheapest for US stocks. Several years of data for most stocks. anfutures have some emini data very cheap.

I'll have to agree with Nitro. This is getting silly. Common sense says that if modern *nix machines can easily fill a good portion of a gigbit ethernet with FTP transfers then you are kidding yourself looking at this sort of stuff when dealing with T1 or E1 speeds at around 0.1% of gigabit...

And this http://www.ejv.org.au/pdf/tunguopen.pdf gives a figure of 150 msecs with a standard deviation of 50 msecs per trade on Globex.

According to this http://www.computerworld.com/hardwaretopics/hardware/server/story/0,10801,96842,00.html roundtrip trade transaction time is about 350 millisecs on Globex. If there is any point to this thread, then some hard quantified facts need to be cited. In this case concerning...

I really couldn't care less and anybody using internet connection would be completely wasting their time worrying about it. Neither do I particularly care if RH 7 is running on a streaming price data server and introducing a 1 msec extra delay if indeed that is the case. It is irrelevent if it...

You might look into how the system clock is adjusted. I don't know about Windows but on Linux there are a couple of different ways of syncing the system clock to a time server. The preferred way on a running system slews the clock so that time is always monotonically increasing. It does this in...

To get a handle on how this works you need a little understanding of how operating systems schedule processes/threads. I'm very rusty on this but I'll have a go. My background is UNIX, but the principles will be the same for modern Windows (ie NT onwards). I'll refer to processes here, but you...
