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.
Almost everyone assumes that trading a short and fastest means to make money (well it looks that way), but the reality you'll only get to know when you get involved. For many the long term endeavour towards making profit is embedded in investment alone but little did they think or know that for you to be a successful trader it's not an overnight attainment but years of consistency (building blocks on your failures and experiences) and hardwork on yourself by learning and relearning...
Trading under pressure to make fast money is a wrong concept, I have seen many newbies that rush into trading because they heard somebody on social media that tells them how they made so much money in trading. Due to the high rate of unemployment in my country many young graduates are looking for skills that they will aquire and be making so much money. They will listen to the many misleading information about how they can make a lot of money within a very short time on trading, they wouldn't know that there is higher chances of losing a lot of money on the same short time. The hard truth is that trading is not a get rich quick scheme, you need to learn the technical and fundamental aspects of analysis before starting and don't let greed and pressure for quick profits to dictate your trade.
