It seems that no one has a reasonable answer for this, I think it's really odd that suddenly they start with the small trades, and next to that, we also observe a negative spike more frequently, yesterday, today, it falls 6 cents and then gradually climbs up again, but why would you sell for 1.33, if the bid ask is 1.38/1.39. I can not put the finger on yet, but will search into the behaviour of the trades.
Hope we see news today or tomorrow!
