Not exactly, but I do trade based on cycles. I really believe markets are driven emotionally, whether it be in reaction to fundamentals or whatever I don't care. I know it sounds freaky and stupid, but it has served me well. It is pretty scarey how often lunar cycles and other celestial stuff is accurate. It is just hard as hell to trade it. And it requires extreme faith like now. If it is wrong, so be it, I won't stop using it.
Helps with fishing too.
And by the way, I am not some weirdo. I can't even identify the big dipper most of the time. I use Menstrual cycles mostly.
