期货网格交易研究分析工具（带主力合约切换）
研究期货网格交易策略在不同配置下的表现，支持多种交易场景的对比分析
核心功能包括主力合约自动切换、强制平仓和重新建仓逻辑

本程序实现完整的网格交易分析流程：
1. 主力合约监控与切换 - 自动检测主力合约变化并处理切换
2. 合约选择逻辑 - 基于主力合约选择算法
3. 基础头寸交易 - 价格-数量网格配置，支持合约切换时重新建仓
4. 网格交易策略 - 限价订单网格买入卖出，合约切换时根据价格条件重新建仓
5. 网格对冲策略 - 带止损的增强网格交易，合约切换时根据价格条件重新建仓
6. 统计分析对比 - 四种交易场景性能分析

主要特点：
- 主力合约自动监控：每日检测主力合约变化
- 强制平仓机制：合约切换时立即平掉旧合约所有头寸
- 智能重新建仓：根据价格条件在新合约中重新建立头寸
- 标准期货盈亏计算：使用正确的合约倍数和期货盈亏公式
- 最终持仓结算：分析期结束时对所有未平仓头寸进行市值计价
- 完整交易记录：记录所有交易包括合约切换引起的强制平仓

期货盈亏计算公式：
- 多头：(出场价格 - 入场价格) × 合约倍数 × 数量
- 空头：(入场价格 - 出场价格) × 合约倍数 × 数量

注：程序支持多个核心商品同时分析，生成详细的交易记录和统计报告
