Bot that buys and sells shares on website.

I"m needing a bot that will monitor a website for prices of shares and buy low and sell high. A picture of the website is attached. You click on invest button then enter your amount. The bot would need to be able to set a random setings so people dont bump up the price if they notice you instantly biding. Also You get paid every month. If you have have a share thats close to the pay date it should wait for the paydate to pass before selling.
