I'm new to the whole stock thing and am just messing around with software doing paper trading and learning as i go. I'm using software from realfasttrader.com. Anyway, what I'd like to know is, can I place an order, and have it filled before 10 am or can you only buy and sell starting at 10? Say I see a stock at $20 at 9:30..If I put my order in at 9:30 to buy it, will it accept the order then and there, or hold it till 10?
