通达信协议用bar开始时间打时间戳(5min线上午最后一根标11:25、下午第一根标13:00;午休11:30-13:00无bar),而Tushare/同花顺/聚宽用bar结束时间(标11:30/13:05)。新增bar_time参数让用户一键切换,避免自行+5分钟偏移。
- 全部3条K线路径覆盖:A股get_security_bars/get_index_bars、扩展行情get_instrument_bars、MAC get_stock_kline(含同步+异步、get_stock_kline_with_indicators)
- CLI kline新增--bar-time {start,end}选项;Web /bars、/bars/index新增bar_time查询参数
- bar_time=start(默认)保持完全向后兼容;bar_time=end仅对分钟级周期(1/5/15/30/60min)生效,自动按周期时长右移并处理跨小时/跨日边界
- 协议解码层零改动,偏移作为纯展示语义在client层后处理,单一工具函数_apply_bar_time_align_df/_apply_bar_time_align_bars复用于全部路径
- 新增27个单元测试(test_codec_datetime.py偏移逻辑 + test_kline_bar_time.py三路径覆盖),全量700单测通过
- bump 版本号至 1.16.0
