What happens if you do not use a stop loss?

Let's assume your trading account size is 10,000 AED and you want to achieve a 300% net profit increase, which means you will exit the market with 40,000 AED if you are right. If you do not use a stop loss in this case, if you are wrong and the market moves in the opposite direction, you will lose everything you have. Therefore, you will have only one opportunity to achieve profit, and if you lose this opportunity, you will not be able to succeed. In this way, your chance of success becomes only 50%, and it cannot be increased since you will not be able to re-enter the market later and correct your mistake.
