Overconfidence: Success in a few trades can lead to overconfidence, where traders start believing they have superior skills or abilities to consistently make profitable trades.
This overestimation can lead to taking on higher risks or neglecting proper analysis and risk management.
Yes exactly if a person regularly wins so they loss their fear of losing so in this way they try to put whole money which sometimes becomes risky for him so I think that whenever a person achieve the desire success so don't change your rules always put less money and if you have certain amount of profit then take the profit and remaining amount will be better for you to keep for longer time also don't be excited for your success because excitation is also a type of emotions which should be kept in control.
