I bought a chunk on the 5th EOD. In fact, i was the one slamming the stock into the close and owned the last trade of the day.
The gap you are speaking of (the following day)was filled. I watched it fill (intraday). My eyes were glued to this stock. The shadow of the candle represents this.
For the MM's to influence any "gap fill sentiment" this would have to be visible on the chart, which it is not.
