Build a simple tool to add share price information to my site

Hi, I am building a new online forum for the discussion of stocks related to the cannabis industry. I want to be able to list in columns all of the stocks on the various stock exchanges around the world, and what their most recent price movement is. You can use the Yahoo API to do this, see here: [login to view URL] The forum website is [login to view URL] I have used Wordpress to build the website. I want a simple piece of code created where I can enter the stock code and exchange of a new stock and it automatically adds to the list at the top of the forum. I want: -Five columns, each ten stock codes long to display the stocks in. -To poll Yahoo once a minute to update the share price while the stock is trading. -To not poll Yahoo at all when the stock isn't trading, so we preserve the number of queries that we are allowed to make to the Yahoo service every day. -I want to display the stock code (ie. 'ABC') plus the most recent share price movement in percentage change next to it, to one decimal place (ie. '-1.5%' or '+7.5%'). -When the share price move is positive I want the text for the stock code and the percentage movement to display in green. -When the share price move is negative I want the text for the stock code and the percentage movement to display in red. -When the stock is not trading (ie. the stock exchange that the stock is on is closed for the night) I want the colour of the stock code and the share price movement to be grey, so people can tell that the stock isn't trading. -Please write the phrase 'mary jane' in your application for this response so I know you have read this whole job description. -The code should have a form that makes it easy for me to add new stocks to the display on the webpage, for example if a new company IPOs on an exchange, then I can add it to the list. Let me know if you have any questions.
