There's insufficient interest to make this a viable commercial enterprise, and LonghornBoy's wariness of reliance on a black box is sensible. But I'm not aware of any set of commonly available combination of indicators which replicate what this strategy attempts to measure. Perhaps LonghornBoy does not describe which indicators he's identified out of respect for an undisclosed approach, but he's under no obligation to keep what he's found secret.

I'll leave readers with two ideas which may be useful to further explore if they haven't already done so. It is terribly easy, at least for me, to assume that shorting is merely the opposite of adopting a long posture. It isn't. With this in mind, an area worth a careful perusal is the phenomenon which occurs as prices change at 'low' and 'high' extremes. For want of a better term, I call this phenomenon 'strain.' Those who look carefully at prices at extremes will notice that there's often useful information that may be missed in merely dwelling on standard deviation plots, and common, not especially useful measures such as 'volatility of volatility' in the volatility realm or far messier technical concepts such as support and resistance.

As an aside, it's peculiar how traders fixate on the latter concepts, using trappings such as Fibonacci retracements or whatever, even as price-action seemingly abruptly disregards any given previous support and resistance levels. It's strangely easy to repeatedly fall back on concepts or metrics which appear to function only elusively or that tend to sputter at inconvenient junctures. That's been my experience with indicators and combinations of indicators prepackaged for technical platforms, in any case.
