The midpoint rule explained

The core calculation in BearBreaker is simple: how far has current value drifted from the relevant cost basis? When that divergence exceeds the threshold, the system drives the position toward the midpoint between cost basis and live value.

If the value sits significantly above the cost basis, the system contracts toward the midpoint. If the value sits significantly below the cost basis, the system expands toward the midpoint. The direction is always the same: back toward balance, never away from it. Inside the threshold, nothing happens at all, which is what keeps the system quiet during ordinary drift.

Targeting the midpoint rather than the full gap is deliberate. Closing the entire gap in one action assumes the current price is the right price, and it leaves nothing in reserve if the move continues. Halving the distance means every action is a partial commitment, and repeated cycles converge gradually instead of arriving all at once.

When Trading holds zero units of a construct, only a controlled fraction of the gap is closed on first contact. This prevents the system from committing too much capital on a single signal. Once a position exists, full midpoint targeting activates. Additional expansion from pure signals is permitted only when price sits below the current TCB average, reinforcing lower-entry discipline. Mirrored pulses from the Intent Core and forced liquidations ignore this average gate, because those actions come from a higher authority.

The midpoint rule is what keeps BearBreaker from chasing prices. It does not try to predict where the market will go, and it holds no view on any company or ticker. It simply responds to the relationship between what you paid and what the market currently offers, and it does so inside the boundaries you set in your own configuration files.
