Optimize Matlab Code - Cointegration

I am looking for two primary things from this project: **Part 1** I am looking for someone to optimize the code highlighted in this webinar. [login to view URL] The scripts which they use are available for download here: [login to view URL] I would like to be able to give an input stream of data to this script in real time. The script should be able to input the data and output buy/sell/neutral signals accordingly. I would like to see a couple of graphs which update in real time. For example: Price, Profit/loss, sell signal, etc **Part 2** In addition to the above, I would like to see a script use the Johansen procedure in the determination of cointegrating relationship in multiple-assets. This means a basket of stocks, for example 3 stocks instead of the two used in this webinar. This part of the project will need a brief write up explaining to me how this works in principal. I understand cointegration, and can conceptualize it when in pairs. I however need someone to educate me on how the principle works when applied to 3 or more variables. All code is expected to be very well commented.
