But suppose that when you start trading real money, you find that after your first losing trade, you get into a winner, but don't hold it for 4 points, you just get out at a profit of 2 points because at least you've back to break even. Well what you've done now is completely changed that statistical nature of your trade methods that should make you be profitable.
Biggest error you can make: you did not follow your system!
One of the most important reasons for going sim first is to learn to ALWAYS follow your rules. So it is clear that you should go back to sim again to build confidence to follow the rules.
You also make a big error in your logic: trading is about results on long term. You can NEVER judge or take decisions or conclusions based on 1 or 2 trades. You said yourself "statistical nature". You should know that statistical relevance depends on a statistical number of events, so clearly not on 1 or 2 trades like you posted.
If you would go immediately life, what would you do if you lose three times is a row and lose 50% of your account? Stop forever? Going sim first gives you the opportunity to learn and to make mistakes without financial consequences or rather disasters. If you master all this you can go life and will be much better prepared for real trading.
