I have been playing the simulator stock "game" with $1000.00, which "charges" $19.99 a trade. It seems to me that if I had a real account, and any time I had a profit of say even $10-15, and could trade for the $4.95 price Tradeking advertises, I would amass little daily profits with which I could play/buy more. Is there some rule I don't know about that one has to keep a stock for a certain period of time? Is what I'm suggesting "daytrading"? Thanks for any info!
