Waitedg: Pretty sure you have to open an account, $500 mininum? I tried to buy at $4.75 today when the ask was $4.75 (but last sale was $4.80). Didn't fill, so changed to $4.80 and they raised it to $5.00 ask as my order went in! Basterds! LOL!
waitedg.. with ameritrade try going to the trade page and enter an order to buy the bid ask should come up, it has been a while since I useed ameritrade so not sure... If you do alot of trading alphatrade works for me but it costs $40. / month although it does pay for itself with the trading i do, pinksheets dot com also has bid ask sometimes but not very accurate..
