I would like to think that the emotional state of any individual trader varies from person to person, such that, while one trader can learn to control their emotions during and after trade, another may be able to just do that, only when they are happy and occasionally.
Trading could be a career or a lifetime hobby that is a sure source of income and where it gets interesting is when a trader has other means of income, is a master or professional trader and is under no pressure to either trade or not.
If a person/trader can't control their emotions during a hectic situation, I think they will also feel the same when they are profiting. Their happiness can also go through the roof. This is dangerous if they have a heart complication because there are some people who are like that who unfortunately die during the process.
Trading is risky and there is no sure income in here but a well-skilled trader can be able to recover their losses and still ends up in the green side. Being interesting can also/only depend on the attitude of the person/trader and not if they have a source of income other than trading. Same goes when it comes to experiencing a pressure.
