Wow!  The text editor for Agora really sucks.  If you enter a link for first text you type in, you're at Agora's Blue Screen of Death.  Not quite - you just can't enter anything more.  Hint - type a bunch of random text below what you're going to highlight, so that you're not Volesofted.

Okay - the OBV came up on the KXL forum - credit to fdrake for it.  Leading indicator based on volume, from Joe Granville.

OBV still positive for SGX, although decaying a bit.  But still positive
