What does it mean to say "Your short is 10 and your long is 20"?

I believe I was trying some erroneous anomolous sequence of steps i probably had no business doing, but it left a little text box on the plot with a watchlist name or something and when I clicked it, up pops a buggy looking request to remove the app from silverlight or remove the silverlight app or something, which I selected thinking the app was just the little unwanted text window.  The next thing I know the TC2000 workspace I was in is gone in a flash and so is the desktop startup icon for it.

So I went back to Worden to get started again, thinking it would reload like the first time, but instead TC2000 started up in my Internet Explorer browser.

The lines appear sharper and crisper to me so I kind of like it, and have tabs right at the top for the this discussion forum and other things is pretty good. But I thought you would want to know what happened.

Sorry.

So now I like the way

 (  C / C'08/09/12'  ) 

levels the field in the present,  but I would further like to normalize the normal fluctuations of the market out of the picture with secondary normalization by a similarly normalized market index, perhaps something along these lines which leads to an immediate formula error

 ( C / C'08/09/12' )   /  ( DJ-30 / DJ-30'08/09/12' ) 

Can I get around changing every formula every day by the use of a global environmental constant or variable that I only need to change once a day?

I want to "normalize" the price history of a stock to it's latest closing price.

I thought I could do it with

C / C0

but the C0 was decremented, day by day, same as the C, so all you get for an indicator is 1.000 all the way back to the begining of time, when all I expect is today's indicator value to be unity.

I tried        C / [C0]       and    C / {C0}      and     C / "C0"      but recieved an error in every case.

Isn't ther some way to treat today's closing price, or any indicator value on any day as though it were a constant?   Something like an absolute address vs. a relative address in a spreadsheet?
