Technically speaking, it isn't the time-frame that determines what type of trader you are, it is the length of time you hold a trade.
Generally speaking
1) Day Trader: Opens and closes a trade on the same day. Usually during cash market hours.
2) Swing Trader: Opens and closes a trade within a few days.
3) Position Trader: Holds a trade open for weeks or even months.
After a while you will realise that there isn't a clear demarcation between 2 & 3 but strictly speaking, a day trader should always close a position on the day it is opened, whether it is in profit or loss. However, most day traders will ignore this rule if it looks like the momentum is strong enough in their favour to continue holding overnight. The flip side is day traders who will hold a losing trade in the hope it will recover the next day. Also, being a day trader does not mean you must trade everyday!
