It is better to trade with a cent or micro account.Real money trading is different from demo trading because of human get emotional when there is money involved and trading psychology will change.
I understand what you're saying. Although I'm hoping to avoid that situation because once I start the account, I am going to try and behave like that money is gone and react as if I am with a demo account. We will see how that works, but I think I have the right personality to do that. I think a cents account wouldn't really work for me, because the losses and gains would be too small vs what I earn in my real career to actually have an emotional response to it.
Live account will certainly test your personality to its limits, that's why it is good advice to start small till you understand your reactions to losses and wins, only trade live with what you can afford to lose while improving,at the same time it has to be worth the effort ,sticking to your Plan is paramount.
