Happy MLK Day! Here are today's updates:

•  Switched out price data sets > The new tickers are ROKU (Roku), NKE (Nike), DIS (Disney), FB (Facebook), BTC (Bitcoin). 
• Optimization > I realized that I was drawing about twice as many objects as was necessary, so I cut it down by half. I haven't tested it yet, but hopefully this will drastically improve performance on laptops and lower end desktops.

I'm going to stick a pin in it for today, but will continue to fix bugs and update this week.
