MQL4 Trend Indicator EA

大多数交易系统使用指标来确定交易信号。 Metatrader 包括 20 多种常用指标，包括移动平均线、MACD、RSI 和随机指标。 MQL 内置了股票指标函数。 您还可以在您的智能交易系统中使用自定义指标。 在这篇 MQL4 趋势指标 EA 文章中了解如何对 Expert Advisor 进行编程以使用最流行的趋势指标进行交易。

趋势指标

移动平均线是最著名的趋势指标。 它显示价格在指标期间是上涨还是下跌。 我们已经了解了如何构造移动平均线交叉的条件。 让我们检查策略进入和退出的其他趋势指标的条件。


如果您转到您的 MT4 控制台并单击插入/指标/趋势，您将获得以下指标列表：


平均方向指数

布林带

商品通道指数

移动平均线

抛物线 SAR

标准偏差

使用注意事项

如果您有兴趣在您的自定义 EA 中插入任何代码，您可以将外部变量复制并粘贴到您的外部变量部分。 然后，使用我的模板作为指导，将指标调用变量复制并粘贴到 start() 函数中的某处，在这些模板下方，您可以复制并粘贴买卖条件。 或者，您可以下载并使用我围绕每个指标构建的 EA。
