Yes you are correct about the origins of the
indicator

Its not something I can easily comment on as people will assume its commercial rivalry!
Actually I really wish Wackena had something special...
I WOULD BUY IT AND PUBLISIZE IT
Developing EA's is such HARD WORK, that I wish someone else would find that Holy Grail...
Looks like I keep on adding to my own portfolio!
Nothing wrong with including open-source in a project - its almost unavoidable in a professional EA as at least part of it will need to do what others (which might have been you, as an author) have done before.
After all, a lot of my code is published!
Issues are:-
Claiming & naming an EA as NN - when it's (effectively) a Slow Stochastic on fixed parameters
Everyone assuming that success in the Autotrade Championship must mean something in the real world
I think the Championship is an excellent idea & should continue but...
Keep in mind the Championship runs on MT data, which is kind to EA's, also
the rules favour near-scalping
