The technique is known as "running the stops." There's a description here: http://www.mypivots.com/dictionary/definition/121/running-th...

Basically, you don't know the stops are there; you make an educated guess.

Ok, if that is what the OP is describing than I guess I understand. But that trade does not have any part of it where the user of the stop loss order shows their hand to someone with inside access. Further, that trade is far from riskless to the people attempting it.
