Can anyone explain this to me? When you go to sell a stock to cash out at a high number is there always someone to buy it? Or are you forced to hold it until a buyer comes along? Is there ever a point when you say sell and nobody buys? I've never been involved in stock trading other than mutual funds and am paper trading now to see if I could learn and play the marked with a small amount of money. All my limited assets have always been in material things like real estate, collectibles etc, that's probably why I'm pretty broke.
