Keep in mind, many of the trades that are going thru may be in the 5 digit range..meaning .00012 to .00018, so unless you have L3 quotation platform and you're a MM, there no way to really tell. Personally, I believe many of the trades that have been showing up @.0001 are really buys but we just cant see it because of the 5 digit range in which L3 is needed.
