First, I always take my smartphone to bathroom, with a position, using SPLASHTOP application, to just reflect what is on my trading computer, although if necessary, I could place an order thru SPLASHTOP.
2nd: trading when ill, is almost always likely to be costly. But it is not the subconscious that helps there, IMO, but knowing very specific rules. For me, esp with ES is that stops need to be wide. Although I also have the emotional impulse to place close stops, that is just not how the mkts work.
