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 ±0.30%、ES ±0.30%、CL ±0.30%、ZN ±0.05%、HG ±0.30%、NG ±0.30%、LC ±0.25%、ZS ±0.30%、DXY ±0.15%、BTC ±0.30%、SH ±0.30%、HS300 ±0.30%、AG ±0.30%、ETH ±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 (per-asset thresholds: GC ±0.30%, ES ±0.30%, CL ±0.30%, ZN ±0.05%, HG ±0.30%, NG ±0.30%, LC ±0.25%, ZS ±0.30%, DXY ±0.15%, BTC ±0.30%, SH ±0.30%, HS300 ±0.30%, AG ±0.30%, ETH ±0.50%). Outside band: close ≥ open → Bullish; close < open → Bearish.
