Correct KnowProphet. More than 3 round trip daytrades in any stock (not just the same security) will flag ones account as a pattern day trader and be restricted.
Also a word of wisdom as I got caught in this trick bag once. If a person is selling a stock they bought on the same day and if they change their sell order after say 1/2 of their shares sold and then they change the sell price to a different price that will count as two DT's.
