Hi, I've read two Dalton books and basically feel the way you do, lots of good knowledge but not really any info on how to trade effectively. I'll put a link to a recent interview Dalton did with Peter Reznicek at shadowtrader.net;

I think you'll find that the use of Market Profile is most useful in context of other technical indicators like Support/Resistance, trend analysis, etc. I've also listened to Steidlmayer and I was surprised in listening to Dalton's interview that they sound very similar in that you can listen to them talk for hours about MP, but at the end you will hear that things aren't the same as they used to be, that MP is used differently now. That there isn't a single solution that you can use MP and make money, you have to be able to adapt.
One thing I picked up and like from Steidlmayer is that you no longer trade TPO's so to speak, you trade time now. When TPO's start to stack up in one area, time is slowing down and you want to wait. You are waiting for volume to pickup at the same time price is breaking out of the consolidation, this is when you will wind up with the P or B profiles, and this is when you will see time speeding up. You want to have your position on before time speeds up and get out when time slows down again. Good luck!
