The problem for a beginner trader in my opinion is skil, emotion, MM. Beginner traders are more likely to have a little knowledge so that many losses are generated, so therefore take advantage of the best demo account to improve skills.
Middle traders are more likely to be unable to hold back emotions and look after MM, I think if you are a beginner trader it is better to learn gradually.
So far I also often lose, even the value is not small but from there I get valuable experience, and experience is my best teacher in trading.
Also the problem is that most people specially newbie or just new to trading do hurry up on doing margin because they do
saw that making money or profits is way too big compared on other system of trading like swings/trends etc. but they do lately
realize that it isnt really that simple and that do really cost them money.
