You can break a trade into 5 phases. Three are intellectual and 2 are reflex. Emotions Boredom, anxiety, wishing Fear, Indecision Fear, Greed, Hope, Anxiety, Fear, Indecision Too much work, Introspection is hard.
Objectivity is harder.
This part is fun for the first hour of the day. After that I start getting a little bored. Phase 1 is simply looking over charts or reading trade rags or whatever, to find setups for the type of trades you like. This is primarily an intellectual process. However, there are emotions that creep in that can really hose you up.
