Great Review! One great tool you can find here is the Metatrader!, LINK: sourceforge.net/projects/metatrader4/ Very COool Tool For traders!
Python users should check out github.com/mrjbq7/ta-lib for a Cython wrapper. Much easier to install and faster than the default SWIG wrapper. It supports Python 2/3.
Easy to install and use.
ta-lib works great
ta-lib is small and works nicely
Seems advanced and useful but, is it in active development?
