00:00:00,362 --> 00:00:01,320 ZAMYLA CHAN: All right. You've finished register, quote, buy, index, sell, and history. The very last thing for you to do is to implement an additional feature of your choosing. You could, for instance, allow users to change their password. You could allow them to deposit more cash into their account automatically, or perhaps you could add a buy/sell button on the index page so that users can buy and sell stocks that they already have without having to look them up every time. Or you could implement something else entirely, as long as it's within the scope of the three examples that I've stated above. Now, there's no check 50 for this problem, so you'll want to make sure to try and break your own website to try and see if there are any work arounds, any corners, any bugs in your code. Or, perhaps, ask some friends and family to break it for you. Ding a ling a ling. The market's open. My name is Zamyla, and this was CS50 Finance.
