I am by no means an expert on this, but we do have to keep in mind that short positions are made up of actual shorts that think the stock will go lower, large long holders that take a temporary short position for part of there holdings as insurance for short term risk and MM that happen to be short because they satified a buy order before they had the actual shares to sell. Some of these price levels are just targets for portfolio adjustments to close short positions and add short positions. there just happens to be 2 sides to a coin at certain price levels. it is easy to set a level at $5, not $4.98 or $5.02.
