编写条件：
放量涨幅大于7个点后连续3天收阴线的选股公式。
编写方法：
XG:REF(C>REF(C,1)*1.07 AND V>REF(V,1),3) AND EVERY(C<O,3);
其他写法：
该公式会筛选出满足以下条件的股票：
- 当日涨幅超过7%且成交量是前日2倍以上
- 随后连续3天收阴线
- 在放量大阳线后的3天内完成三连阴形态
公式中使用了BARSLAST函数定位放量大阳线位置，COUNT函数统计阴线天数，确保连续收阴条件。成交量倍数和阴线天数可通过参数调整。
{参数设置}
N:=3; {连续阴线天数}
RATIO:=2; {成交量倍数}
{放量条件}
VOL_REF:=REF(VOL,1); {前一日成交量}
COND1:=C/REF(C,1)>1.07; {涨幅大于7%}
COND2:=VOL>VOL_REF*RATIO; {成交量是前日2倍}
IS_BIG_UP:=COND1 AND COND2; {放量大阳线}
{阴线判断}
IS_DOWN:=C<O; {当日收阴}
DOWN_DAYS:=BARSLAST(IS_BIG_UP); {距离放量大阳的天数}
{选股条件}
XG:DOWN_DAYS<=N AND COUNT(IS_DOWN,DOWN_DAYS)=DOWN_DAYS AND DOWN_DAYS>=3;

指标使用通用经验总结
- 一般出现信号不急着立即介入，介入时机一般尾盘半小时判断信号是否可介入；
- 指标信号出现后第二天冲高阴线，立即清仓，等待突破上一个信号点最高价判断是是否介入；
- 指标信号出现后第二天阴线或假阳线，立即清仓，等待突破上一个信号点最高价在判断是否介入；
- 在上涨，现价处于上涨高位的『介入、看多』信号不参与；
- 不是信号一出现就介入，要根据市场环境，量价关系，市场情绪等诸多因素判断是否可介入；
- 技术指标有其本身局限性，宁可错过，也不要做错；
- 拿到指标后，多测试，多练习，看是否符合预期，总结规律；
总之一旦信号失真，不符合预期，立即清仓控制风险 ；
