How I predict tomorrow's price for any portfolio

I have been calculating next day pricing for the Dow and S&P for years. There is no real magic to it, and the same can be done for any portfolio stocks, as long as there are at least six companies; the more the better, but not really necessary above a couple dozen companies within your portfolio. I'll give you very accurate pricing for the upcoming day, both for a good day up or a not so good day down. This is a new blog which I've just created and am currently constructing a website in order to provide subscribers both next day pricing and high probability entries on that next day. That information will be helpful for individuals on both extremes of the spectrum, from day traders to long term investors. More to come. Let me know if this may be of interest to you.
