There are a number of GUI package managers such as kpackage for KDE. Just click on the package icon in a file manager and you can install via a GUI. No command line. Install from an ftp URL as well a local files etc. These things have existed for years. Kpackage for example shows a list of...

So which is more difficult: # apt-get install some_package or typing in some wierd activation key ? Even worse having to ring up MS and waste a substantial amount of time obtaing an activation key.

You have a couple of options. 1. Wine. http://www.winehq.org Wine is basically an implementation of Win32 API on Linux/Solaris etc. Some Windows software works and some doesn't. You may have to play around to get something to work. It's possible to replace individual Wine dll's with...

You clearly aren't aware of the Linux software packaging systems such as employed by Debian, RedHat, Fedora, Suse etc etc. Linux software packaging is not perfect and neither is Windows with the abomination that is called the Registry being mangled by all sorts of malware at will. There are...

You are seriously misinformed if you believe MS invented the windowing GUI, or even produced the first commercial implementation. The original research work was done by Xerox and the the first PC style device was the Apple Lisa (Jan '83). The first incarnation of X (The predominant UNIX...

Indeed. I really fail to see why Matrox would lose any competative advantage by releasing full specs for older cards - the G200 MMS for example. The thing is so old it even has a DEC PCI bridge controller chip on it. If HAL were open and specs available I might have a go at seriously tracking...

I am aware that Matrox in the past had a good attitude to open source X11 drivers, but the situation is not the same today. Just scan through the support forums on the Matrox web site to see that there are quite a few issues with drivers for multihead cards. All the specs are not open for...

It seems from the API release notes that you can get up to 6 months of data. If you request 1 min bars you get 1 day's worth per request. For five minute bars, you get 1 week of data per request. For each request you specify the end date for the requested data. By making multiple requests with...

Huh ? Most distributions will install within an hour, autodetect your network, USB mouse, video card etc etc. No more difficult than installing Windows. What special configuration do you need other than possibly Xinerama for multiple monitors ?

Please no more Linux distributions. There are more than enough. However, I can think of one thing that does need attention and that is support for multihead video cards. In particular somebody should put a rocket up Matrox to open source their drivers and open up their documentation...

How are weekly pivots calculated ? Over the previous calendar week (Monday to Friday) ? Or over the last five trading days eg supposing it is now wednesday would the pivots be calculated over the period from last wednesday through tuesday ?

I have had multiple problems today. 1. No SPI (SNFE) streaming data before the HSI open. Backfill fine. View market data connections shows green for HK and all other farms. Restarting TWS did not help. 2. After open of HSI, required restart of TWS to get HSI streaming data even though HK...

This is just from memory so I may only have part of the story, but I think there is an issue if an app via the API attempts to attach a trailing stop to a limit order that has already been filled.

Just for accepting client connection requests, I believe.

You don't need to do this anymore. Have a look at Configure->API->Trusted IP Addresses. You can set a list of client IP addresses from which connections are accepted without manual confirmation.

But what have you gained ? What problem are you solving ? Not CPU utilization and not memory utilization, because they really aren't issues. If 'light' is a virtue, and I agree in general it is a good thing, you want no TWS at all and no local intermediary server. The application binds or...

In principle I agree, but one needs to take a practical aproach which is to pressure IB to fix whatever issues there are in TWS/server side reliability. I havn't seen any issues with the basic GUI features of TWS that in my view contribute to unreliability. CPU utililization is a non issue...

I think it should be based on the account size required to trade the system, not on intraday margin requirements. That is the amount of money tied up in trading the system.
