dayraider,
Overnight margin in a customer account is 2 to 1. If I own 1000 shares of stock at 50 , I would be required to keep $25,000
in my account. Pattern Daytrader margin in a customer account has been increased to 4 to 1. A pattern daytrader must maintain a $25,000 account. A pattern daytrader is defined as trader who
daytrades 4 or more times in a given week and these four trades
constitute more than 6% of his/her total trades for that week. The
4 to 1 margin is the max allowed for the pattern daytrader in a customer account, individual brokerages do not have to allow 4 to 1 daytrader margin, if they do not want to.
In a trading L.L.C. that is not a member of the NASD, overnight
margin is determined by the firm. There is a max margin allowed
for the firm under SRO and SEC rules, but this is too complex to go into. For individual trading members of our L.L.C. , we allow 5 to 1 overnight(in liquid NASDAQ 100 stocks & S & P 500 stocks) ,
with no more than 3 to 1 margin in one stock . L.L.C. margin is only available to Series 7 licensed traders who understand the risks associated with professional margin.
