Trading is difficult, and more if you are just a newbie and you do not know much how to trade, because you are going to lose a lot of money because of that, actually. The greed is the biggest mistake
Losing maybe part of trading but being a newbie is not a valid reason to lose, you lose because you do not know what you are doing, you did not research well in short you did not made your homework on what to do when you are still starting. We can always minimize our loses if we only know what we are doing.
A new trader can be effective in trading as long as he is packed with the necessary knowledge and wise enough to not be affected by outbursts of emotion. Being a newbie does not excuse one from being too ignorant in trading effectively although experience is an important advantage. Information is already available in many resources and coupled with common sense, one is way to go in good trading.
