With all the changes taking place in the NYSE (SHO, Hybrid, etc.), is tapereading the specialist and scalping still a profitable strategy? I have added tapereading/scalping as one of my strategies for about 8 months now and currently feel that the introduction of hybrid has made this strategy a lot harder. In fact, it is almost impossible to have an accurate read on a stock now because of all the whipsaws. Any thoughts/opinions?
