Re. B/A size - it is my favorite pseudo TA tool (sort of demand-supply measure) You are right. Larger the block size at Ask, more likely it will go down. The opposite is also true. Of course, if it were that simple every one would be rich! -g-
I have noticed that these larger blocks appear even larger at $1 increments for most stocks. For example, if Dell B/A was 40 7/8 and 40 15/16, the next time B/A move by 1/16, (ask at 41) you will invariably see a much bigger block than the one at Bid. FWIW, I think this should be a secondary measure to FA.
