The same absorption in both regimes

This is the central point of the course. It fits in one sentence: your order flow read does not change with the regime. Its meaning does.

Above the flip

An absorption at a level, in a positive regime, is an institutional limit with a hedging flow pushing the same way behind it. Price approaches the call wall, an offer absorbs the buy aggression and reloads; meanwhile, market makers sell ES into strength. Your fade has a tailwind. Two players, one of them mechanical, are working for you.
