This is great advice. Emotions can trip you up when moving from demo to live, and this means you have to be careful even if you had good results on a demo account.Unfortunately, no articles will help you out.
I think that the most efficient way to use your first days is to observe yourself and your psychology. You'd better start with small sums and you can try to implement all the trading strategies that you used in your demo trading and see how they work. You should pay attention to the slippages, spreads and all other kinds of commissions, so that you will be able to understand whether your trading strategy needs some adjustments and alterations. More than that, you should pay attention to your psychology and your feelings. You've got to understand whether real trading is different for you in the emotional aspect or it is quite the same. If it is different, then what exactly makes the whole thing different. Later on you can increase the lot sizes gradually so that you'll feel calm and avoid any stress along with the increase of your deposit.
