解说

        所谓“长剑射天，股价落地”，是指股价进入高位后，出现一条长上影小实体K线，该形态具备如下特征。

        1）应是上影较长的星形小阳或小阴线，而且长影长度是实体的2倍以上。

        2）当天成交量有较大幅度的提升。

        3）必须是处于股价高位或者波段顶部。

         出现“长剑射天，股价落地”的形态后，股票投资者需遵循以下操作原则。

        1）此形态出现在上升行情的价格顶部是强烈卖出信号。

        2）本形态出现频率相当高，能在任何部位形成，但只有在高位出现时，方为可信卖出信号。

    卖出口诀 - 长箭射天，股价落地
    解析：
    1. 出现一条长上影小实体K线
    2. 长影长度是实体的2倍以上
    3. 成交量有较大幅度的提升
    4. 上影线要高于前一日高点
    自定义：
    1. 较大幅度的提升 =》 前一日的两倍
    2. 小实体 =》 K线实体是前一日收盘价的1.5%以下0.5%以上
    3. 卖出时点 =》 形态出现后下一交易日
    4. 胜 =》 卖出后第三个交易日收盘价下跌，为胜
    只计算最近两年的数据
