Also know that more than 85% of traders are losing. Especially those that going long and short position.
I found this to be true when I started trading because I discovered that the people who think that all traders are successful are those who do not trade at all and look at traders from the outside but the moment you begin trading and you understand what it's about and the risk involved, you begin to see for yourself that most traders that appear successful actually have their success from other means and not trading itself. The number of successful trader is very few, but it is still very possible to be among the very few successful traders.
