My Background : I am a long term software professional who has left his day job to become a full time trader. All my trading systems are developed from scratch using Python and associated technology stacks. I can help with the following -
* Usage of python for data mining
* Integration with a backend DataBase
* Downloading and Converting Data into minable formats
* Usage of Numpy, SciPy, MatPlotLIb, Pandas etc packages to fully utilize and leverage pythons immense power.
* Plotting of back-testing results for easy visualization
* Developing APIs for automated trading via Interactive Brokers.
However, I would not be able to help with PyAlgoTrade. That's a platform I had personally verified for my own usage and have finally decided in favour of using Pythons own packages instead of PyAlgoTrade.
