For example, there was a spread between the Bid and Ask price but not particularly great...at most, 0.10. I put in a Sell at 2.11 (1000 shs.) and the stock opened at 2.18 and stayed there for at least 1/2 hour at a volume of 6,000+ shares. It's Last was 2.11 on a volume of 9650 shs and it's low was 2.01. It is an OTC-BB stock. I had the same Sell order the previous day when it's Last was 2.12 (however, put in the Sell order after it hit a high of 2.15).

Can anyone tell a dummy exactly how shares are traded when there is a lower Sell price than what is accepted? Why would anyone buy a stock at 2.18 when they could get it at 2.11??

The only way around this is to put in market orders or keep changing your limit.

My basic knowledge is with NYSE securities which are handled differently. This blows my mind!
