It's not just who buys. Where matters.

The same act — buying — can tell two opposite stories depending on where it happens. In the auction, location is the message. To read it you need one reference first: the value area, usually the prior session's.

Responsive: buy cheap, sell expensive

Responsive activity bets that value holds. It buys when price dips below value (perceived cheap) and sells when price pokes above it (perceived expensive). It is the force that keeps balance, pushing price back toward agreement — range-day rotation lives on it.

Initiative: attacking outside value

Initiative activity bets against the status quo: it pays expensive prices above value, or hits cheap ones below, because it believes value itself is misplaced. It is the force that breaks balance — and if it also earns acceptance (chapter 1), new value is born, and with it the trend.

The 2×2 matrix profile readers use

Two questions — who acts, and where — give four stories. Buying below value: responsive (a bet that value holds). Selling above value: responsive (the same bet, other side). Buying above value: initiative (value should sit higher). Selling below value: initiative (value should sit lower).

Now you know who does what, and where. Next: which game is being played — the day types.
