Now my question is
~why can't we relate demo accounts to real accounts
~why do you think people still start making losses on real accounts after long time trading demo successfully
Because of the obvious, demo account is just like that, it's purpose is for you to test how trading, no real money involved just the experience.
But with real account, it's very different, there is this pressure already that you will net to perform just like what you did on a demo, very successful. But then again, this entails real money so just a simple mistake will make you lose money. So we shouldn't compare the two, at least take advantage of the demo account. But it doesn't mean that you can replicate it to real trading account so we have to get that on our mind when we go on real accounts.
