使用说明：
[*]参数优化建议：
[*]趋势市场：增大ChannelPeriod(25-30)，降低ADXThreshold(22-25)
[*]震荡市场：减小ChannelPeriod(15-20)，提高ADXThreshold(27-30)
[*]高风险策略：RiskPercent(2.0-3.0) + ATRMultiplier(1.0-1.2)
[*]保守策略：RiskPercent(0.5-1.0) + ATRMultiplier(2.0-2.5)
[*]特殊功能启用：
[*]时段过滤：设置UseTimeFilter=true并配置交易时段
[*]移动止损：设置UseTrailingStop=true并调整倍数和步长
[*]加仓功能：AllowMultiLots=true时自动按倍数加仓
