指标解读：

一、前期准备部分

记录前收盘价

PREVCLOSE1 := REF(CLOSE, 1);和PREVCLOSE2 := REF(CLOSE, 2);

这两句就是把昨天和前天的收盘价记下来。

这就好比你要判断一个人现在是不是状态变好了，得先知道他之前啥样，这些价格记录是为了后面比较股价是涨是跌。

自定义指标计算

O1 指标：

首先计算(CLOSE + LOW)/2，这是综合了当天收盘价和最低价，大概看看股价位置。然后和过去 10 天里这个值的最小值比，挑大的，这是在找股价相对强势的时候。再用指数移动平均（EMA）处理（周期为 1），除以 3 后加 3 次，得到 O1。可以把 O1 想象成一个能体现股价短期复杂波动后的一个参考值，在图表上用黄线表示。

O2 指标：

O2 是对 O1 做指数移动平均（EMA），周期是 3。这就像把 O1 的小波动再磨平一点，更能看出中期趋势，在图表上是洋红色线。

O3 指标：

O3 是对 O2 再做指数移动平均（EMA），周期 3，从更长期角度看股价走向，是绿色线。这三个指标就像三个侦探，从短、中、长不同时间角度侦查股价是要涨还是跌。

移动平均线定义

MA_SHORT := MA(CLOSE, 5);和MA_LONG := MA(CLOSE, 20);

分别计算了 5 日和 20 日移动平均线。5 日的就像看短期股价平均位置，20 日的看长期。

短期均线敏感，长期均线体现大趋势。

二、买入信号部分

AAA 条件买入信号（图标17 桔子 ）

条件解读：

当CROSS(O1, O2) AND CROSS(O2, O3) AND CROSS(O1, O3)，就是 O1、O2、O3 这三个指标线从下往上交叉，这就像三个信号灯一起变绿，意味着从短期到长期股价趋势都在变好。再加上MA_SHORT > MA_LONG，短期均线在长期均线上方，说明短期股价强于长期，市场比较乐观。而且V > MA(V, 10) * 0.5，成交量也比较活跃，比 10 日成交量均线的一半还多。综合这些，就像各种因素都在喊 “快买，股价要涨啦”。

VAR19 条件买入信号（图标9 钱袋 ）

条件解读：

首先看PEAK1 := (CLOSE > PREVCLOSE1) AND (CLOSE > PREVCLOSE2) AND V > REF(V, 1) AND ((CLOSE - PREVCLOSE1)/PREVCLOSE1 < 0.1);，

这是说收盘价高于昨天和前天，成交量比昨天大，而且涨幅小于 10%，这是股价温和上涨且量增的情况。

从VAR2到VAR18这一堆变量是在看之前的状态延续情况。VAR19是综合了之前这些状态延续、当前满足PEAK1条件、MA_SHORT > MA_LONG（短期均线大于长期均线）和V > REF(V, 1)（成交量比昨天大）。经过FILTER过滤（每 5 个周期只取一次），当VAR19 = 1时，就像又一个买入信号亮起。
