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.
Your emotion lies on you especially depression, that's why rationality comes in place at these times especially in trading.
The thing is some people have different mindset in trading.
Some bring their emotions and some do not.
Some invest funds that's worth losing and some, at worse, even do loans just to do panic comeback to their trades.
