也许理念并非原创，指标却是自己思考的结果！

原理：个股涨停一段时间后，回落至涨停初最低价完成了吸筹、洗盘等步骤，并遭遇3，5，8，13，21天等时间窗口，有可能拐头上升，甚至再次涨停！

说明：主图，依据量柱涨停理念，分别在最低点和中点画线，并加以涨停时间窗口。
            副图，每遇收盘价回落至涨停价最低价周围时显示“警戒”字样。同时遇时间窗口，则显示“时间窗警戒”。副图中加入本人比较喜欢的短期威廉指标，可以在回落时间窗点，并且WR>80时考虑买入（供参考，买卖靠个人！）。
           选股公式：个股涨停后收盘价回落至涨停初最低点，遇时间窗2，3，5，8，13日时选股(加2日选股,防强洗盘现象，去热度消退的21天选股）。选股出股后，再结合自己的理念公式买卖,比如本人提到的短期威廉指标。
