Johnny Walker and fader, and anyone else I may have missed, thanks for your kind comments!
The NN CCI is my abbreviation for my neural network commodity channel index indicator based trading system. It is my own work based on 1 year of ZB data. By my own work I mean I designed the criteria, not the software.
In my regular working hours (I'm not being specific on purpose) I work on data mining and data analysis involving just under a terabyte of data. I use WEKA (open source machine learning software) for this analysis plus wrappers I've written myself in python and java.
For my trading work, I rely on a third party vendor for the foundation and create my own stuff on top of that. The main issue is that, while I could write everything myself using WEKA and my own java classes, it would take too long. It is better to work on the inputs and the data rather than building the foundational clases yourself.
