Day trading rules: I have been buying and selling a certain stock over several days.....?

Question

I have been buying and selling a certain stock over several days, obviously because I am making short term gains. My question is am I considered a day trader if I buy and sell the security in the same day 4 times in a 5 day period. or if I buy or sell the same security 4 times or more in the same 5 days? Like am I considered a day trader if I buy a security once every day for 4 days, would I be considered a day trader or must I buy and sell in the same day every day for four days. Im a little confused. Thanks!
