"""趋势突破统一筛选器（自上而下方案，中短线交易定位）
|
||
|
||
三阶段管道：
|
||
Step 1: 板块定位 — 找到有资金流入的热门板块 (3-5个)
|
||
Step 2: 板块内选股 — 在热门板块成分股中筛出有资金流入的候选 (30-50只)
|
||
Step 3: 深度分析 — 供需 + 价格行为 + 趋势 + LLM (10-15只推荐)
|
||
|
||
评分公式：供需关系 50% + 价格行为 40% + 趋势 10%
|
||
板块和资金流作为前置过滤条件，板块涨停数作为情绪奖励。
|
||
|
||
风险乘数：惩罚取最大而非叠加（防过度惩罚），奖励可叠加。
|
||
|
||
数据源：
|
||
- 盘中模式：Tushare 日线 + 腾讯实时行情 + 东方财富5分钟K线
|
||
- 盘后模式：Tushare 当日完整数据
|
||
|
||
止损止盈：基于市场结构（阻力位/支撑MA/近期低点），而非固定百分比。
