If the liquidity is limited then the spread tends to be wide or wild. Real time quotes may be from different market makers. Look at the streaming data from Silicon Investor to see the bid and ask "lot size" offers to tell posted market maker have changed.

You have to look into Nasdaq trading data, to see how many market makers are registered and what volume they trade in each month. Then you want to look at shorts on the stock. If the lead market maker shorts the stock, the party maybe over soon. Each market maker has his own customers; they don't cross each other. If a single large trade occurs, make ready to take profit(usually up 10% on the day).

It is a complex issue, learn philosophy first then learn methodology of trading. Flexibility counts in investment analysis. Good luck on all your investments.
