How do you cope mentally with ups and downs

You are right every one should think like that , Market not give you profit all the time. You have to loose if you do mistakes or do not follow marker. After loss I will try to do next trading with much care where my loss will be less if I am not in profit. I have to minimize my loss to improve my trading.

you are thinking and emotionally reacting like a employee of a company. you go to work and have a task to complete. the company has all the safe guards and procedures in place to ensure you successfully complete your task, and should you not succeed or need help the company provides it.

As a trader you have to create those procedures " trading style/system" and safe guards “money management”. And after it has been tested with time and you believe it to be successful. then you will find it emotionally easier
