"""盘中实时扫描
|
||
|
||
盘中 Tushare 的 daily / moneyflow / limit_list_d 等接口尚无当日数据，
|
||
因此盘中扫描采用混合策略：
|
||
- 板块热度：使用前一日 Tushare 数据作为基线（哪些板块是近期热点）
|
||
- 个股筛选：用腾讯实时行情替代 Tushare 的当日 daily_basic / moneyflow
|
||
- 技术面：历史 K 线（Tushare） + 当日实时价格（腾讯）拼接后计算
|
||
|
||
盘中重点捕捉：
|
||
1. 热门板块成分股中，盘中放量拉升的个股
|
||
2. 量比 > 1.5、换手率适中、涨幅在 2%-7% 的活跃股
|
||
3. 用实时价格更新支撑/压力位和技术信号
