//1. Appel的MACD指标，他的交易理解是：市场的交易是脉冲式的，缩减的脉冲暗示调整近在眼前，而扩张的脉冲暗示市场即将继续上涨。
//2. 他类比高尔夫球的运动，抛物线轨迹，从飞行的角度和速度判断落点，而球在上升过程中速度逐步减少，斜率逐渐归零，然后开始下降。
//3. 综合，他关注的是动量的变化，是一个短期的趋势指标，缺少对长期和总体的把握。
//4. MACD是一个双均线系统，所以理论上可以追踪长期走势，但他本人没有用这个的描述长期变化的想法。
//5. 只是推断，Appel设计指标的初衷，可能只是为了提早的发现金叉和死叉。
//6. 都市传说，其中的参数MACD(12,26,9)美国一周六天班，交易六天，12是两周，26是一个月只放四天假，鉴定为假。Appel自己的说法是，纯交易经验。拍脑袋来的。
//7.1Appel给了一个建议，“长均线是短均线的2-3倍较好”，短期线的时间跨度越短，则越容易捕捉到短期的价格变化，但是也会增加噪声。
//7.2信号线DEA的参数建议设置到3-9，他是MACD的移动指数平均线。
//8. 他给了三组建议的参数，分别是(12,26,9)，(5,13,9)，(19,39,9)，其中第一个是最常用的，第二个是短线交易者的选择，第三个是中线交易者的选择。

Overview

MACD computes a fast exponential moving average and a slow exponential moving average from the chosen price source, taking the difference as the DIF line. An exponential smoothing of DIF forms the signal line, while the difference between them plots as a color-coded histogram. Users can adjust the fast length, slow length, signal smoothing length, and source price. The script plots oscillator lines without built-in alert conditions, trading signals, or automated execution rules.

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
