Quote from AMT4SWA:
I know this by looking at the volume distribution from my experience with delta. I can see evidence that buyers of the lower 840's were compelled to thin out inventory as price rallied from their buy zone (up to a pivot high of 887.00) and then traded back down (to a pivot low of 862.50). The distribution of delta volume formed as price traded the 862.50 pivot area, and then 866.75 pivot area on the 30th of April shows me enough evidence. The distributions show me buyers from the next lower levels lost confidence price would hold (so they dumped inventory with the thought of at least locking in some profits on remaining positions entered from the 840's). The thinning out of inventory was probably done with the thought price WAS GOING TO come right on back down to lower 840's.
In regards to 862's from your question......yes, some bailed at 924's to 927's......and more will thin out on each failure of support as price drops back towards 862's again. Reading the delta volume distribution as this plays out is how I have gained my edge. I use this edge to determine what is or is not a significant zone to pay attention to.....this was developed over time through my experience with delta and auction market theory.
