the widest spots are where the most trades took place, the most longs vs shorts, so there are leftover shorts or longs, folks who were wrong, at those prices, the market moves up to resistance,down to support, spots where enough buyers or sellers are waiting to stop a move(break even on their previous loser),thats what the wide spots represent,so those spots on the last chart were the wide points today,so as long as we dont break above or below it will bounce to and fro ,those points ,temporarily chart below has arrows showing several wide spots
