I also seen this that percentage of newbie traders in forex is very small. Only a few earns profit but that is not really for their expertise. Most of the newbie like us depends on indicators and on luck. Sometimes they really works but not always. So it's really hard to calculate the percentage. there is a way people have to really understand about trading, it requires a lot of time to understand and you should never just jump to the market like that, thats why most newbeie will just lose the frist round.
