fast, Cyber apparently only monitors margin accounts to see whether the term "pattern day trader" applies to account holders. (...require T+3 settlement in cash accounts.) I'm having trouble getting the same answer twice from Cyber. My current understanding of their policy is that cash accounts, whether above/below $25K, can daytrade until they "use up" their cash. For instance, you start the day with $30K, buy/sell 500sh of a $25 stock, you've "used up" $12,500 leaving you $17,500 to trade with. You then buy/sell 1000sh of a $17 stock using up $17K, leaving you with $500 to trade with, no more. The next day you start fresh with $30K (adjusted for your gains or losses the previous day). I'm told the T+3 Settlement rule applies to you withdrawing funds from your cash account, not daytrading within the account. So if I follow Cyber's thinking for cash accounts, you have no margin, you can't short, you can daytrade until you "use up" the funds that day (that is, you can only use funds once), you start fresh the next day, you can only withdraw funds after waiting 3 days for settlement. If anyone is sure of something different, please post what you know for certain.
