### Comment:
Can you explain further please? I'd like to know more about this.. Is it even legal though?

### REPLY:
Sure it's legal. Let's say you set a limit for $100. Your broker will find someone selling for $99.99 and buy it from them and then sell it to you for $100 and keep the penny. You paid what you wanted to pay for the stock, the person selling the stock got what they wanted and your broker uses volume to make lots of money. There are no rules that force your broker to get you the best possible price.

### END.
