OK, sorry to keep posting one after another here,..
but as I'm reading through the above site, I realized a potential "gotcha" that would be good to stay aware of.
The Liquidity Quote can just be a summation of what's in the book. It "may" contain additional shares from the crowd or specialist, but then again it may not.
So, at least for my setup, I'll have to do some fast math/estimating to see if there are additional shares being bid or offered at that level. It may just be a repeat of what I'm already seeing in the book.
For example, looking at JPM right now, (midday doldrums), it's trading at the point (36.00) and the offers in the book show 1800 at .02, 1200 at .03, 2500 at .04, and 2300 at .05, with a liquidity quote of 13,200 at .05.
So, that tells me there's currently 7800 offered in the book, with another 5400 coming from the floor and specialist.
Watching this for a while shows that it will bounce all over the place--right now, it's down to 2200 shares by the crowd/spec...
I guess the value of this, and my ability to do fast comparisons, remains to be seen.
