You won't even think about trading under pressure if you are learning to trade the right way. You cannot trade under pressure if you read trading books, have mentors, be a part of peer group of traders. The people who are likely to trade under pressure are those who are greedy and want to make it a get rich schemes. Trading for them is short term and not a long term endeavor.
Even with trading the right way people still want to get that cool cash quick so they hasten up the process to achieve that and end up trading under pressure, so no one is exempted and that's because there are alot of money problems so they think trading can give them the money in no time forgetting that it requires patience. Another thing is seeing that it favours another and you want to go into it as well and end up handicapped under an pressure to do so and lose everything.
When someone wants to get quick profits from the trades they make, of course they will go through the analysis stage before deciding to choose the assets they will trade and this will certainly be very risky for them because they go through the analysis before deciding to trade, patience in trading is certainly needed so that they can know the right time to enter in order to get profit from the trade, so everyone who wants to trade of course they must be able to control themselves so as not to do things that are detrimental to themselves when trading because everyone who wants to trade certainly hopes for profit, so they must be able to do it well in order to make a profit, of course there are many things they must prepare before deciding to trade, don't just see other people can make a profit from their trades then we decide to trade of course that is very wrong.
