Luck is a small factor in trading but it can make a huge change in some situation. HOwever, in day trade, I believe that skills are the most important things you need to have. If you do not have skill or experience, do not ever make a day trade. It can destroy your balance less than a month. Without any skills or experience, day trade will become the same as gambling. And you know, people are addicted to gambling although they always lose their money. THErefore, I suggest you should learn trading before making your own day trading
