Sample · the intelligence layer

Coldpine signal scoreA 0-1 composite from four weighted factors: disclosure speed, trade size, cluster activity (multiple members buying the same name), and the member’s track record. ≥ 0.65 is the high-conviction tier; ≥ 0.50 is moderate. Trades from trust-managed members are penalized (× 0.2 multiplier). It’s research, not a recommendation.
