One good piece of advice from Wyckoff's day trading bible, is to save th tape to study it later.Quote from Don Bright:
I think I have all the books on tape reading...and I agree with Maverick...not much help at all. There is a black book, written decades ago, that was pertinent at the time....but even the guy who wrote it says that things have changed so much that his own book lacks value.
Mav is right about watching the actual prints, all the while looking at the bid/offer spread and size...but the prints are the most telling.

The way I see it, if you study the tape long enough you're gonna start catching patterns [like a buyer or a seller for example; or particular ways in which the specilist for that market makes money] once you see the patterns you can test them, and then study your results at the end of the day and try to see patterns on the historic tape [a lot easier cause you know what happens next, kinna like watching the sixth sense for a second time, you see alll this things that give away bruce willis being dead...]
About the squad box, I think it's a great tool once you start listening to what's being said and you start using that information to your favor... It's a lot easier to spot a buyer/seller there, since you can hear "Bear is buying 200" or "Solly is seling 50"...
