News Close Confidence
What it does
Confidence floor that triggers a full position close. When the classifier's confidence for an opposing headline reaches 0.90, the entire position is closed immediately regardless of current P&L or loss depth. Breaking news receives a 0.10 confidence boost (urgency_breaking_boost), so a breaking article at 0.80 effective confidence acts as 0.90 and triggers a close.
When to change it
Raise to 0.95 to require higher certainty before closing. Lower to 0.85 to act on less certain signals. The high default prevents noise from triggering closes.
Safe range
0.80 (sensitive) to 0.95 (only very high confidence).
Example
Classifier returns confidence 0.88 on a negative MSFT article (non-breaking). Below 0.90 close threshold. No close. Same article tagged breaking: effective confidence 0.88 + 0.10 = 0.98. Close fires.
