The chicken or the egg?
Sentiment is cyclical and predetermined by previous hidden cycles, most important of which, is volume..If that is true, then sentiment driven by options are a localized method to derive sentiment..Hence, sentiment/options are a derivative of volume through time, not the other way around and volume in previous demand zones (zoomed out and hidden to naked eye) is the true underlying factor for sentiment . For sentiment occurs as a result of a growing snowball of energy, and VOLUME IS ENERGY. If that is true, then forecasting sentiment CORRECTLY, far in advance, can be quite true..
