Tape Reading

["Wooglin" <wooglin.org@xxxxxxxxxxx>]

I am looking for source material on the old 
fashion art of tape reading. As I understand it, someone with a trained eye and 
a good memory could watch the tape and see the accumulation (or distribution) of 
a stock followed by a price change in that direction.
 
I am looking not only for explanation of the 
technique itself but also the trading tactics that go with it.
 
Thanks,
 
Jim Barone
