something I noticed this morning about 10-15min before open the buyer side and seller side where stacked well above current like starting at 18 on sell up to 25 and 18.5 on buy down to 13. Exactly one minute later it was cleared and as we see it now. I say this only because I believe brokers use the market depth as a way of communicating imminent news to each other. I have shares all be it as a gamble (that didn't pay off) in TPT and exactly the same thing happened each day before three sets of ann but not on any other day. This is just a theory I have and I didn't pay attention to it until i saw this happen this morning and not on other mornings.
