Haven't seen any hidden stuff in Wyckoff.
From my understanding of Wyckoff, one should avoid identifying particular bars and focus on the action of numerous bars — more wave orientated. A bit like the Weis wave concept. Extreme bars and volume are noted and depending on the following action could be potential changes in trend. That is just my view of it, others may have a different interpretation. I don't practise VSA.
Have seen those courses on Dayton's site but never coughed up for them. Are you finding them helpful?
