Taylor is excuciating to try and follow, but has some good observations on how stocks move in addition to the Buy Sell Selll Short sequence.
I think you would become very unstuck trying to trade Angells LSS as a system. my observation is that the cycle appears and dissapears, I suspect depending on whether longer timeframe players are active, and I cannot even rule out that it is actually random, although volume patterns do sem to confirm that there is orcestrated activity going on.
