most brokerages limit you to three or four round trips (in and out) in a 5 day period on a margin account. Any more than that and they mark you as a day trader. In order to get past that most require you to have minimum of 25,000 capital in the account.
Best to check with your broker to determine their requirements and stipulations as they do vary some.
