This is why traders focus on stocks like this one, because they can be volatile and they can herd retail, which is basically what you and a few others do apparently, professionally.
Except the trading action on NWBO is textbook dilution pattern, with volume matching up perfectly with the increase in OS.
There is no extra volume to account for swing traders. It's simply insiders selling into the market. Traders don't focus on low volume stocks like this. You are exactly wrong. When only 0.08% of your OS is trading in a day, swing traders tend to avoid that, because it's too easy to get stuck.
This is quite simple and that you can't see it says a lot about your investment literacy.
