Lets say finance company abc is selling shares of wgle they got in a finance deal with wgle. Now they lets say sold 38 million shares to any who wanted them. They sold some at .0001 and .0002. They filled every order that popped up at either the bid or the ask.
Same senario but abc is selling shares at .0002. So all the trades at .0002 could be new shares hitting the market that day. All the trades at .0001 are just that, trades between investors.
