News Reduce Confidence
Setting key
news_confidence_threshold_reduce
Default
0.75
What it does
Confidence floor that triggers a 50% position reduction (halve the contract count; remainder stays open). A 1-lot position cannot be halved; it is fully closed instead. The reduce tier has a loss-depth cap: positions already underwater by more than 2x the credit collected are not reduced (left to stop/DTE/delta rules instead of panic-reducing).
When to change it
Lower to 0.65 to reduce on less certain signals. Raise to 0.85 to reserve reductions for stronger signals only.
Safe range
0.65 (more reductions) to 0.85 (fewer, higher confidence only).
Example
Classifier returns 0.77 confidence on opposing news, above the 0.75 reduce threshold but below 0.90 close. 2-contract position: close 1 contract, keep 1. The remaining position continues under normal management.
