The strategies that Market makers are using are much more complicated than it is described in the article.
The same example IBM.
The market maker sold 1000 at 100.3, .2, .1, and then buy 3000 at 99.6, because of stop loss order, may face big loss if it causes more sell in IBM and related stocks and then futures (if orders are big enough). It is gambling, not market making. From time to time one stop loss order can cause more stop loss excutions.
It is good to buy only 1000 instead of 3000. I do not think this kind of opportunities exist in us equity market anymore. Could be in other markets. And also it is not likely legal if it traded by same specialist, I am not very sure.
Anyway, some info is very interesting.
