Thanks for the kind words @alpacho78. 
When I refer to Market Makers, I'm referencing whales on various exchanges that drive price in one direction or another. They often do this by putting legitimate orders on the books, or false order walls (only put up for show, but never executed) to create a perception of reality. Sometimes that perception is accurate, other time's it's not. Remember, trading is a zero sum game. For 1 person to win, someone else must loose.
