the truth is, EVERY bid whack gets sucked up, and in many cases the bid actually rises after it's hit.. here's why; whenever it appears a big seller is on deck there are also BIGGER buyers waiting for those shares, hence, bidders fall over themselves in an attempt to grab em'..
these buyers could care less about the 50k sells, they'll let those go, BUT let a 500k sell come on deck and WHAM, they'll take those in a flash..
look at time & sales, it's all there for viewing, you'll see EXACTLY what I'm talking about..
EXPH has all the makings of astronomic upward explosion when the time is right, and that time is very close..
