There is a popular saying which goes this way ''The goal of every business man is to maximize profit'' and this saying is the central philosophy of so many trader. Let's be honest, most people get into trading because they want to make profit.
This is the main goal of the people why they are committing with the world of trading, because of the chance to get an extra earnings with the market, and if we check it this is not the reality instead we tooks over time and effort just to perfect our trading execution and not all trades are wins so we need to set our mind, effort, and self to be prepared what will happen with the market movement.
Things like setting stop loss, not putting all of your money in one single trade no matter how sure you are, understanding your risk to reward ratio, knowing when to sit out a trade , all of this makes a huge difference. Its not about being scared but being smart.
Sometimes people says the market can be your friend either an enemy and one of the best thing you need to do is be prepared if this happen having your stop loss and take profit gives you an advantage until where you will make a trade, until when you will hold to prevent over trade and over engage with your position. Always stick to the trading plan.
