One core word that i feel has not been discussed is the fact that after learning trade through demo; you still have to relearn when you are trading a live market; because they are glaringly 2 different things. Also, either demo or live trading; do not practice or learn trading with huge sums of money; learning takes time and needs consistency
Demo and live trading are the same in all angles except that emotion is involved in live trading... Lol. In live trading , you are scared to take certain risk or not to allow your orders to roll on because you don't want to lose your money. Decisions you freely take in demo, you are not free that way in live trading because you know is real money. So the difference is that one is fake money in practice and real money in business.
In the setup, strategy you apply, indicators, all are the same with emotional difference.
