EnsembleV2Strategy — 修复版集成策略
基于 EnsembleLooseStrategy(时间窗口共振逻辑)全面升级:
修复的 BUG:
- BUG1:旧版 populate_buy_trend / populate_sell_trend → 改为 populate_entry_trend / populate_exit_trend
- BUG2:卖出条件 min > max(永远不满足)→ 修复为正确区间
- BUG3:'buy'/'sell' 列名 → 改为 'enter_long'/'exit_long'
新增功能:
- UMACD + Volume 时间窗口共振(核心创新保留)
- ATR 动态止损
- 全部参数 hyperoptable
- custom_stoploss 动态止损
- 中文注释
作者:基于 EnsembleLooseStrategy 重构
版本:V2.0

EnsembleV2 集成策略
核心创新:时间窗口共振
- UMACD 信号出现后,在 N 根 K 线的时间窗口内
- 如果出现 Volume 突破确认,视为有效共振信号
- 这比要求同一根 K 线同时满足两个条件更灵活
