解说

        所谓“三种图线交叉点，卖出股票需抢先”，是指均线交叉、MACD线交叉和VOL成交量交叉。在最近两天内连续出现这3种图形交叉，投资者需要尽早抛售手中的股票。

         出现“三种图线交叉点，卖出股票需抢先”的形态后，股票投资者需遵循以下操作原则。

        1）从上图可以看出，5日移动平均线交叉10日移动平均线，5日均量线（VOL:成交量指标）交叉10日均量线，DIF线交叉MACD线。该形态从三种不同角度客观地分析市场动向，为投资者判断行情恶化提供行之有效的脱身依据，属于大跌之前的最佳卖点。

        2）在这种股市形态的实战中，5日均线交叉10日均线，从趋势转化的角度分析上档承接无力，股价只有通过下跌方式寻找新的支撑；5日均量线交叉10日均量线，从上涨缺乏量能配合角度衬托下降的必然；而DIF线交叉MACD线，则从股价顶背离的角度显示弱势状态。

        3）当股价处于高位区域时，出现三种图线的同一天或间隔一两天的时间里交叉的走势，可断定趋势已经彻底转变，此时卖出股票虽然已错过相对高点，但可以躲过随之而来更为凶猛的下跌行情。

策略代码

1. 上文解说中MACD使用的是DIFF与MACD的交叉，本策略使用的是DIFF与DEA的交叉

2. 本策略检测的交叉均为死叉

    卖出口诀 - 三种图线交叉点，卖出股票需抢先
    解析：
    1. 两天内连续出现均线交叉、MACD交叉和VOL成交量交叉
    自定义：
