Day trading means buying and selling in a very short perspective. Normal traders hold their positions for weeks, months or even years. Day traders hold them for about one day at maximum. While normal traders do about one trade per week, a day trader do three to five per day.

Most day traders choose to sell their positions before the day is over. That way they have no positions over night. The advantage with this is that the risk of loosing money over night is gone. It is quite normal that the price for one stock starts at a different price as it closed with the day before. This can of course also be used to an advantage. If a trader now or believe that a stock is going to rise during the night, he will buy close before closure and sell it directly at the opening the next day.

The biggest problem for day traders is the lack of discipline. They start day trading without enough experience from trading. When they realize that they are losing money, they close the position directly. That way they have definitely lost money. Often it is advisable to wait, because the price is going to rise again. But to know this you have to have a large experience in trading. And you have to be disciplined.

Day trading for a living will probably at the best stay a dream for most of us.
