V8 Changes (fundamental improvements, not just filter toggles):
- Increased ATR multipliers across all timeframes (stickier line)
- Minutes: 3.3→3.8
- Hours: 3.0→3.5
- Daily: 2.8→3.2
- Weekly: 2.5→3.0
- NEW flip threshold (0.5%): Requires price to move beyond line by % before color changes
- Entry buffer enabled by default (0.20 ATR vs 0.15)
- ADX minimum increased to 18 (from 14) for stronger trend requirement
- Core HalfTrend logic modified to require threshold breach before flip
Goal: Reduce flip-flops while maintaining high-quality trend signals
Test against v6 (filtered) and v7 (pure flips) for comparison
