Trading requires having a solid guidlines and discipline. One of the hardest thing to overcome in trading is emotions because it mostly lead to many losses. This is a bigger problem than trade going against you. An important thing is to only trade with what you can afford to lose, accept that trading is not getting a quick rich scheme. When you deposit money on an exchange, you accept losing it all but also you’ll do your best for it not to happen knowing how much it will take for you to get that money. Fix your risk per trade percentage and don't go all in a trade with your full capital. Do not be pushed to increase your trade stake when you are in profit to maximize it or recover your losses. This is the emotion that you should curb to make it in trading.
It is good when you have your emotions under control; it helps you in trading. If you are very composed and emotional balance; it helps you to stay calm during a huge profit cap in trading; and helps you to stay even more calm when you run into losses. Your stable mindset reminds you its time to take profits when you unnecessarily fall in love with a certain investment.
