I figure you have a couple of choices.
One of the things I use is ATR(1) -- the avg. true range for one
period, or the true range between today and yesterday. I like to know
that number, and you can also simply use
(c - ref(c, 1))/ref(c, 1)
For part of my chart title, I include:
"ATR: " + NumToStr(ATR(1), 4.2) + " ( " +
NumToStr((C - Ref(C, -1)), 4.2) + " / " +
NumToStr((((C - Ref(C, -1)) / Ref(C, -1)) * 100), 2.1) +
"% )
It's a snippet, so look out for unbalanced parantheses, quotes, etc.
