I just had to repeat the following because this is really the best way to look at it,,, this is how open source works at its best. Everyone has total free access to the code, everyone feels like they have "ownership" and is motivated to contribute. Many of the motivated people actually will...

"""Based on what I learned, people always talk about Linux being free, but he points out that most people who have Linux buy a distribution in a box. And many of those were "Official" Red Hat Linux. Plus Linus, the creator, gets plenty of funding.""" This is old information and...

"Tickzoom sounds more like fantasy more than reality. I am betting this all BS. We get one of these threads on here about once every year." I don't think so. This guy has too much knowledge on this to be BS. I think he has some code that he has written and has a good idea as far as open...

Hi Big, You are talking about client side. What substantial open source projects are using C# ? I can't name a single one. What major financial exchanges, data feeds and providers, major financial institutions, etc run their servers or processing on MS/C# ?? I can't name a single one...

The system that Wayne has is modular and uses a high performance engine at the lowest level. At that low level there are many math functions and other stream processing functions that will be needed. These already exist in open source code and do not have to be rewritten. They are in C++. I...

Hi Big, The vast majority of high bandwidth back end code for the financial industry (as in stock market, not banks and branch banking) is written in C++ and runs on Linux. Period. If you are talking about front end code and client workstations and client/server systems for banks, etc -...

Both Nvidia and ATI offer C compilers and infrastructure to use their GPU's for Math processing. This is a great idea in case the speed is needed. http://arstechnica.com/news.ars/post/20070219-8878.html http://smart-machines.blogspot.com/2007/02/nvidia-makes-it-easy-to-do-math-on.html...

Also think about compatibility with financial industry systems programmers that may want to contribute. Almost all of the cutting edge development on the latest stream processing and CEP (event driven) systems for the financial industry is being done on Linux and C++ with some Java mixed in...

If you want to look at other large open source projects: OpenOffice - C++ and Java Linux - C and C++ Firefox - C++ and Java Anyway almost all the big ones are C, C++ and Java or a combination of them. There are many of them, just open the Synaptic package manager on a Ubuntu system...

Hi Wayne, As far as speed benchmarks are concerned that is just one concern. Java has been gaining ground but the speed king is C and then C++. If Java keeps improving there may end up being no difference. With the processor speeds now the difference may not be significant, But that is not...

Also, on Linux you can use other free open source software mostly written in C++ (or code chunks from this software) such as Scilab (http://www.scilab.org/), QuantLib (http://sourceforge.net/projects/quantlib/), MonetDB (http://en.wikipedia.org/wiki/MonetDB), Scicos (http://www.scicos.org/)...

Yes, I agree with all your points. Java is great but my thoughts are that for the main engine you want the performance of C++. The main thing as far as environments go is to have the engine and core of TickZoom not be locked into an MS environment. Some additional thoughts on Linux/C++: 1...

Hi Wayne, I have been following this thread but haven't posted anything yet because I wanted to digest all of this and not add to the clutter. I am very interested in supporting this and have several programmers that I work with that would be as well. You are doing a great job so far, and...

I just was checking out Sierra charts and noticed that their data service is provided by Barcharts. I have tested Sierra extensively durring the past week and it runs very well with IB/TWS. In just TWS alone if I open about 6 tick data charts my CPU usage goes up a lot so for effective fast...

Does anyone have experience using Barchart.com data and software? I just looked at the site and it looks very interesting but there is very little about it that I could find on Elite Trader which is surprising because they look like on of the major sites as far as web-charts. I was looking...
