编写条件：
MACD绿柱二次缩短的选股公式。
编写方法：
macd:=”MacD.maCD”;
AA:=BArslAst(MACD<=REF(MACD,1))=1;
XG:AA AND COUNT(AA,BARSLAST(MACD>0))=2;
其他写法：
该公式通过BARSLAST函数定位MACD转负位置，结合SUMBARS函数统计绿柱缩短次数，实现二次缩短条件检测。
核心逻辑包含：
1)当前绿柱缩短状态判断；
2)确保前次缩短发生在红转绿之后。
参数SHORT、LONG、MID可调整周期参数
{参数设置}
SHORT:=12; {短期EMA周期}
LONG:=26; {长期EMA周期}
MID:=9; {DEA计算周期}
{计算MACD指标}
DIF:EMA(CLOSE,SHORT)-EMA(CLOSE,LONG);
DEA:EMA(DIF,MID);
MACD:(DIF-DEA)*2,COLORSTICK;
{条件1：当前绿柱缩短}
COND1:=MACD<0 AND MACD>REF(MACD,1);
{条件2：前次绿柱缩短发生在MACD>0之后}
AA:=BARSLAST(MACD>0);
BB:=SUMBARS(COND1,2);
COND2:=BB<AA;
{最终选股信号}
XG:COND1 AND COND2;
{可视化标记}
DRAWICON(XG,L*0.98,1);

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 ；
