The brain and psychological research would say that a blend of conscious and unconscious competence is what you want. You can also use your conscious to to help your unconscious - ie sleep, breaks, tracking the feeling of sensing when you see a pattern develop as well as other feelings and emotions.
With trading, I am not so sure this is the right way to parse it though.
Relentless uncertainty causes your brain, thinking and feeling to react in a different way than something more precise. I think that working with the reality that you can never know for sure - all you can do is sense patterns. And, the fact that you will perceive patterns BEFORE your conscious tells you, is the place you want to shoot for.
In other words, your objective should be to know the difference between an intuitive feeling and an impulsive one. You can consciously work on this. In doing so, you add a layer of knowledge that you can learn to integrate into a process.
I don't mean to be vague - but it is a case of rethinking what it really means to think. We do half of that (not precisely, I say half to make a point) with our bodies. We haven't been taught however to use that in school and in fact have been taught the opposite.
