MACD背离自动画线通达信指标公式源码MACD（Moving Average Convergence Divergence）是一种常用的股票技术指标，用于分析股票的趋势和交易信号。
MACD背离是一种常见的技术分析方法，用于判断趋势的反转点，即价格走势与MACD指标走势不一致的情况。

-然后计算了MACD指标的快线(DIF)和慢线(DEA)，采用了指数平滑移动平均线(EMA)的计算方法。
-最后根据顶底背离的条件判断，通过比较前一日和当前日的最高价和最低价，以及前一日和当前日的DEA值，来确定顶底背离的信号。
在图表上，通过DRAWICON函数可以绘制出顶底背离的箭头标志，上箭头表示顶背离，下箭头表示底背离。
请注意，这只是一个简化版的MACD顶底背离指标公式，具体的实现还需要根据具体的需求和市场情况进行调整和优化。
对于股票投资和分析，建议综合考虑多个指标和因素，进行综合分析和判断。

上述代码是通达信公式语言的源码。
首先定义了一个背离判断函数BackwardJudge，这个函数用来判断价格序列dd中的顶底背离。
接着定义了MACDBackward函数，这个函数首先获取MACD指标的DIFF、DEA和MACD序列，然后调用BackwardJudge函数分别判断DEA和DIFF序列是否
存在顶底背离。
然后根据判断结果返回背离类型，如果DEA存在底背离，则返回1；如果DEA存在顶背离，则返回2，否则返回0。
以上便是MACD顶底背离的通达信指标公式源码。
