Free powerful trading tools software for linux

Simply Powerful ToolKit in short SPTK is a powerful widget toolkit based on the Fast and Light ToolKit (FLTK).
The goal of this library is to create the easy-to-use, compact and effective library of controls to extend the abilities of FLTK library.
It is geared for business-style application development with database support (ODBC). All the widgets support database connectivity. A special CDialog class makes editing database records very easy. Every widget can be connected to the field, and CDialog can be connected to the database table.
Most of the controls are database-bound. If you place them on the CDialog-derived window they can load and save information from/to database.
This is the first release version of my controls(widgets) library that was designed to work with FLTK. Im using it for about a year in the production project.
Enhancements:
- Fixed a bug in CField::asString() that cause returning an empty string for some non-empty fields.
- Added couple of small fixes for better error hanling in CRegistry.

Trading-shim is a database driven connector API that provides a persistent store SQL backend database.
The trading shim is a command-line and dbms controlled interface to the socket-based API of Interactive Brokers Trader Workstation, abbreviated as the IB tws socket api, or simply tws api. That api has a number of advantages for our purposes, including the freely available Trader Workstation, comprehensive feeds and archives for tick and history data, a paper account ideal for software testing, and low transaction costs.
The downstream drives the shim by making changes to the database. The shim consults the database at initial startup, and from time to time thereafter when signalled by brief, simple commands. This combination of database and shim integrate persistent database storage with the tws. The command interface also serves as an alternative to the existing tws gui interfaces, to permit you to use downstream programs, whether gui or not, to drive the tws through its api.
The shim is written in C++, and though developed on Linux, should run on any modern Unix-like platform. Its free software; weve released the trading shim in source form under the GNU General Public License in order to reach the widest possible community of users.
Enhancements:
- This is a major release, adding significant documentation, with manual.pdf.
- It has support for IB TWS Build 872.6.
- Full shim binary regression tests have been passed for the Debian testing platform as well as CentOS 4.
- UTF-8 support has been added.

Network UPS Tools is a collection of programs which provide a common interface for monitoring and administering UPS hardware. Network UPS Tools uses a layered approach to connect all of the parts.
Drivers are provided for a wide assortment of equipment. They understand the specific language of each UPS and map it back to a compatibility layer.
This means both an expensive "smart" protocol UPS and a simple "power strip" model can be handled transparently.
This information is cached by the network server upsd, which then answers queries from the clients. upsd contains a number of access control features to limit the abilities of the clients. Only authorized hosts may monitor or control your UPS hardware if you wish.
Since the notion of monitoring over the network is built into the software, you can hang many systems off one large UPS and they will all shut down together.
Clients such as upsmon check on the status of the hardware and do things when necessary. The most important task is shutting down the operating system cleanly before the UPS runs out of power.
Other programs are also provided to log UPS status regularly, monitor status through your web browser, and more.
Enhancements:
- HAL support. IPv6 support.
- Support for many new devices.
- Many driver improvements.
- This release uses automake.
