Ah, so Mr. Zones has a champion in Mr. Neck. Let us address "always in the market." Procedurally, you will agree, this is easy to do. I assume that you question whether one can actually make money that way. Clearly on a timescale of months, one can, reversing at bubble blowoffs on the upside and at excesses of panic on the downside. I even believe you can do it on a timescale of weeks, using our revered Mr. MurrayTTurtle's 50 day ema. But can one do it intraday? I have a very accurate algorithm that finds every high and every low. If one reverses at every high and low, regardless of the timeframe, the system is a big loser. So clearly the trick is to find a filter that says "reverse on this extreme but not on that one," that is, to pick the "real" highs and lows. Mr. Hershey observed and codified the P-V relation for that purpose, augmented by classical trendline and channel trading. On any time frame. For any trading instrument with sufficient liquidity. Sometimes his P-V relation is so clear as to be axiomatic. Other times, in my opinion, not. But that is probably due to a deficit of perceptual skills on my part. I think the trick that makes it all work is the bracket order waiting for breakout of congestion. Consider an up day. At the probable peak of the morning, Mr. Hershey will reverse to short. If his congestion, convergence and centering (CCC) occurs, he does not care if he is right or wrong being short. He will get right, if necessary, with the bracket trade on the CCC breakout. If CCC does not occur, he just keeps trading the P-V relation. Clearly from the journals of Mr. Hershey's adherents, this is not always an easy thing to do, especially on a narrow range day. That is what separates the Nwbprops from the Spydertraders. Can I do it? I would not even try, as I have a diametrically opposed view of market action based on support and resistance. But that does not prevent me intellectually from seing the truths in the Hershey method. So can one make money "always in the market?" I can't. Doesn't sound like you can, either. Why is it so hard to believe he can? Perhaps a little faith and willing suspension of disbelief is in order. As Sam Clemens wrote, "A Christian is a man who believes in what he knows ain't so."
