I disagree that classic wisdom doesn't work. It merely needs to be appropriately conditioned on actual market structure, scaled appropriately, etc. The roles of supply and demand do not change. The implications of liquidity and leverage do not change.
not sure about wisdom, but most of the classical market theories don't work as such. scaling, conditioning, structuring them differently would not make them classical as such anymore. it's always good to know the basics though and use that knowledge as much as possible.
"The roles of supply and demand do not change. The implications of liquidity and leverage do not change." 100% so. those are some examples that are basic, mostly static fundamentals of economics.
