/**
 * 🎵 COHERENCE-BASED TRADER 🎵
 * 
 * THE REAL AUREON SYSTEM
 * 
 * Based on README methodology:
 * - Entry: Coherence Φ(t) > 0.938
 * - Exit: Coherence Φ(t) < 0.934
 * - Win Rate: 85.3%
 * - Expected Value: +1.42% per trade (before fees)
 * 
 * Core Formula:
 * Λ(t) = S(t) + O(t) + E(t)
 * 
 * Where:
 *   Λ(t) = Lambda - The unified field state
 *   S(t) = Substrate - 9 Auris nodes respond to market
 *   O(t) = Observer - Self-referential field awareness (Λ(t-1) × 0.3)
 *   E(t) = Echo - Memory and momentum (avg(Λ[t-5:t]) × 0.2)
 *   Γ    = Coherence = 1 - (variance / 10)
 * 
 * Run: npx tsx scripts/coherenceTrader.ts
