Speed up loop in webinar

Hi there, by looking at the algorithmic trading webinar and files : http://www.mathworks.com/matlabcentral/fileexchange/29489

I am running algorithmictradingdemo1.m and I realize with larger data sets the code takes forever. If there any ways to speed this up?

I tried to use gpu to speed it up but it actually slows it down.
