watching btc ticker had a ?

does mt gox or another exchange have market makers? i see huge limit orders on the bid side at just about every dollar amount. were talking 500 coins and up. that is one of the golden rules of trading not to use limit orders because you either miss on the way up or your trying to catch a falling knife when falling. for example  I just cant comprehend someone buying 500 X $85 =$42500 worth of coins on a limit bid with such little volume. Or is this Mt gox putting in stop gap measures to prevent a freefall? It is in their best interest to keep this thing going and being orderly about it. I have watched the ticker pretty closely over the last few days and its been trading a pretty tight range seeing there are supposedly thousands and thousands of people waiting in line to spend their money?

those huge blocks on the bid have to be mt gox covering their shorts. there is no uptick rule here.
