The psychological aspect of trading is “extremely important”, and the reason for that is fairly simple. A trader is often
darting in and out of stocks on short notice, and is forced to make quick decisions. To accomplish this, they need a certain
‘presence’ of mind. They also, by extension, need discipline, so that they stick with previously established trading plans.
They also must know when to book profits and losses. Emotions simply can’t get in the way.
