Market Makers have certain trading codes (signals as such) relaying information to other maker platforms.
100 I need shares. 200 I need shares badly, but do not take the stock down. 300 Take (or I am taking) the price down so I can load shares 400 Keep trading it sideways. 500 Gap the stock.
These are examples. A trade of 911 is a signal for "incoming news". I find it curious that that there were 5 of these 911 trades during the last few minutes of the trading day.
There is a possibility that we may be hearing something shortly. It doesn't mean its for certain however.
