Santo Mining Corp (SANP)

Walls is a form of slang meaning that the level 2 shows an abnormally excessive amount of shares for sale at a particular given price. Typically walls are put up by either an idiot retail investor trying to sell too many shares at once or crooked market-makers trying to cause intimidation in the price to suppress it back down, because they are trying to trade and make a profit as well. Some investors when they see walls tend to just give up and sell their shares for less. That's playing right into their hands.
