MArtingale and anti martingale combined into same strategy / EA

I am putting information together to build a system that combines martingale and anti-martingale in the same strategy in order to automate it. I wonder if such a system already exists out there.
Please provide me links to any relevant information, both forums where I can discuss mathematical algorithms behin those logic, links to documents, researches or anything of help.
Once the EA is completed and back tested with satisfaction, I am willing to make it available here for free and as a service in specialized forums.
