// === DESCRIPTION ===
// High-conviction swing bottom entry strategy using optimized MACD(3,10,3) and RSI(21)
// Entry: Point-based scoring system for swing bottoms (divergences, momentum, price action)
// Exit: Inverse scoring system for swing tops (no stop-loss, exit only on swing top signals)
// Position: Single position with 100% allocation, scores displayed only when ≥10 points
// Based on analysis showing 23.7% improvement over standard parameters
