Pressure, Friction, Participation
Framework
The entire Book Duplex system can be compressed into three variables:
- pressure
- friction
- participation
That compression is useful because every primitive belongs to one of those buckets or refines one of them.
Pressure
Pressure is the directional tilt in the system.
It is mostly expressed through:
Pressure answers whether one side is structurally or aggressively dominant.
Friction
Friction is what makes movement hard.
It is mostly expressed through:
Friction answers whether the market can actually absorb a directional push.
Participation
Participation is whether real capital is present.
It is mostly expressed through:
Participation answers whether the move is being funded right now.
Deterministic Rules
RULE:
IF pressure up
AND friction low in the direction of the move
AND participation confirms
-> continuation probability increases
RULE:
IF pressure up
AND friction high near the execution zone
AND participation remains strong
-> absorption question, not immediate breakout
RULE:
IF pressure ambiguous
AND friction collapsing on both sides
AND participation quiet
-> liquidity vacuum, wait for the next flow impulse
What This Framework Prevents
It prevents single-metric thinking. For example:
- high displacement alone is not bullish or bearish
- strong buy flow alone is not continuation
- positive net imbalance alone is not immediate support
The read only becomes stable once pressure, friction, and participation are evaluated together.
