Hey Greg,
Thanks for your reply. I know my purchases are really small compared to yours. I thought I read on another page to always use a limit order and I was curious to how people came up with what they wanted to bid.
I guess if you are buying in small quanities to just buy at market price and get the shares.
At least now I know later when I'm buying 20-50 thousand shares to use limit order with the lowest price of the day!!
Thanks for all your help
