My fellow biochemist,
You said you do not need to educate yourself, and then you ask questions that are easily answered. The answer to all of your questions is fairly straight-forward: supply and demand determine the spread, bid, ask, etc. That's the easiest way I can put it. If you want a lesson on exactly what determines the bid and ask, I once again would ask that you educate yourself. Do you own DD on how the market works, or, I should say, how NASDAQ works. Recent changes in the trading laws do not allow the games you speak of. If someone wants is not willing to pay the bid, they can place whatever limit they want as close to the bid as possible and force the spread to narrow. As for large swings in price with small volume, that happens all the time (once again, supply and demand). If there is small volume, but they are all "buys," you will see the price jump.
Reading my original message, I must say it sounds rather harsh and a bit demeaning. I apologize if it came across that way to you. I certainly was not trying to sound that way.
Take it easy,
