You wont understand how to become emotionless unless your own money is up for risk, in my experience with trading i didn’t take it seriously just trading with a demo account. Yes you can get pretty good at trading with fake money but it is not the same as when you could lose all your money.. When using your own balance you are able to think more carefully before placing a trade, you check all your fundamentals are in place before placing the trade and you are more involved with the trade.
Obliviously this isn’t for everyone and i can understand that but in order to be successful you must learn to take risks, the biggest regrets in life come from not taking a risk when its presented to you. You dont have to agree but those are my thoughts on the subject.
The more you trade and fail the more experiences you have to learn from, as long as you analyse why you failed and learn from it you can ALWAYS make back any losses.. I do not recommend chasing your losses but over time you will recover any loss and you will gain a fair bit more in the process.
