DislikedInformation-gathering stage and critical decision phase, in other words:

"as emotion-free as possible"
Nevertheless, to quantify and track one's current feelings and emotions seems a safe route. And, most people (1) can use emotions at least sometimes for decisionmaking.
An emotion is a directive built upon a feeling.
Feelings -- a gut or body pattern about the environs concerned in order to project from it -- often have a screen: [list][*]Someone else's...Ignored
Your idea of feeling leading to emotion isn't clear. Is "feeling" otherwise termed "knowledge one isn't confident in and/or sure how one came to have"? If so, it's easier to still term it knowledge.
Based on my observations, study and thought, emotions are a consequence of knowledge; knowledge is anything that one knows.
EDIT: I would subcategorise knowledge by how it was gained. EG. actively, passively, by inference. This will help you banish "feeling" from your vocab and thought: it isn't a helpful term. Passively gained knowledge, that is knowledge that one didn't intend to gain, could be otherwise termed subconscious knowledge: most of this is knowledge gained by experience and I think this is the root of your "feeling". Because this knowledge is passively gained, recollections can be misty and possibly erronous.
More people, traders especially, need to get to grips with the fact that to have any thought/feeling/anything there must be knowledge that leads to it. The term "feeling" suggests "inferior knowledge" to me: knowledge gained passively, vaguely remembered and possibly erroneous.
