Update data ajax api -- 3

Currently, I have a table a table which new data stock price data is being put in every 2 mins I need to make that page update every second and be delayed by 15 mins I also need to box overlay that goes over the price when the price has changed I need this done by today [login to view URL] and [login to view URL] page do not bid if you can't finish before 16:00 Data should be cached or stored somewhere on server so we don't make a crazy amount of api calls on refresh Also change the chart to candlestick chart
