"You are correct insofar as that is what the market is for that sale. But odd lots are not reported ie if an odd lot is at the bottom or top of a daily market, the market daily high or low report will not include that trade."

True, but what I'm getting at is the slowdown of momentum that this creates in buyers when they see the sp stalling/dropping.  Instead of jumping in and seeing an accelerated price, sentiment changes and the price shifts downward.  This ultimately affects the top and bottom of the day.  The odd lot is inconsequential other than that.
