from what I've read, limit buying/selling does not always guarantee a buy or sale, since the stock might not reach the limit you've set, and unless you're greedy, selling or buying at market price could be just fine if its unlikely the stock will rapidly change in value, or any change that does occur does not harm you. For instance, say you buy a stock at $45 per share, and later on you want to sell it and notice it has gone up and is currently going up that day, and its current per share value is $49.50, so you put in a limit sell for $50. If no one is willing to buy it at $50 per share, and it then goes back down, you've just screwed yourself out of some profit. Had you put in a market sell, it likely would have sold around $49.50.

Unless I've misunderstood the mechanics of all of this...
