One of the things that affect some traders is that they don't accept their loss and move on, some traders will want to make back all the money they have lost since they started trading, they carry this as their most and only priority, and that leads to them losing more money.
The reason why you will keep losing more money when you don't accept your losses and move on and stop trying to win back all the money you have lost is that, when you want to win all the money you have lost by all means you become aggressive in your trading and when you are aggressive the effective power of your knowledge will gradually decrease leading to you making mistakes in the course of your trading which will lead to lose, so if you keep trading with the same mindset of winning back all your losses you keep being aggressive and keep losing.
So to avoid more lose as a trader accept your losses and move on, keep an open mind and you will start gaining more than you are losing.
Life happens your loss should be used as a lesson and motivation to achieve success.
This mindset has really messed up a lot of traders who think they can do it but at the end they realized they have been nothing but stupid. Whenever someone lose money, definitely they will be angry and agreessive especially when the used what they can not afford to let go but aggressiveness doesn't make them lose power rather they will become mentally unstable, they won't be thinking the way they were thinking before starting the trading because they will be depress and depression always cause a change in emotions and that is what course mental instability. The remedy to this is to have a self discipline and ensure to use what you can afford so that you won't have the thought of trying to get everything back after loss because if you try, you will be doomed.
