Not being evasive. This is strictly non directional trading, looking for theta. Which you would do if you believe there is expectancy in selling options.
Calculate expectancy by taking the win rate times average win and subtract the losing rate times average loss.
for example...
another perspective is that atr oscillates around a base due to mean reversion. if atr is > or < base then the prediction should be skewed to the oposite. the simple formula is atr/close resulting in an indicator which somewhat behaves as an oscillator. The idea here is the dominant market...
Simply that B-S does not reflect skew, and, in my view, causes the vix to under estimate probability of touch for puts, and at different times, overestimate and underestimate probability of touch for calls.
