BearBreakerThe TCB ledger
An honest record of the money you actually spent
The Trading Custom Cost Basis is a pure capital-deployed record. When the system expands, it simply adds the capital spent and increases the unit count. Everything else in BearBreaker reads from this one number.
Contractions raise the bar
When it sells, a specialised formula lifts the average cost of the units that remain. That is deliberate. After a profitable exit it becomes harder to buy again, which locks your discipline in place instead of relying on willpower.
Started from real holdings only
The ledger is set up from your actual Trading holdings when it needs to be, never from the Intent Core.
Only real fills count
The ledger, the cooldown states and the outcome journal update only after a fill is confirmed. Orders that were accepted but never filled, or cancelled, or rejected, leave every record untouched.

Adjust the numbers below. Watch how a profitable contraction raises the average cost of the remaining units, which makes the next expansion harder to justify.

Ledger result
This sale is profitable, so the ledger lifts the average cost of the remaining units from $95.00 to $120.00. Future expansions must clear this higher barrier.

The ledger is one half of the story. The architecture explains where the signals come from, and controls and safeguards covers what stops it from doing too much.
