Quote from eusdaiki:
I posted an article about the merger on the trading forum. I don't think it approaches the issue of tape reading directly, but it should be a good guide of what we can expect from the merger.
Once the NYSE goes 100% electronic and the specialists are gone, tape reading as we know it will be over. The whole idea about reading the tape has to do with recognizing the patterns of one person, the specialist. Once the market becomes fragmented and electronic, this will simply not be possible. All good things usually come to an end.
