MrWigglesworth 这是一个加入了Dema作为4型的版本：ma__dema_crossover_with_arrow_and_email.mq4

很好!非常感谢你的帮助，MLaden

节日快乐！!

现在有谁能从代码中自动找出经纪人的格林尼治时间（而不是我自己的格林尼治时间）？

现在有谁能从代码中自动找出经纪商的GMT（不是我自己的GMT）？

没有自动查找经纪人的方法（在所有的数据中没有这样的信息--甚至在新的metatrader 4中也没有--至少我没有发现）。

嗨，mladen。

我曾经问过一个关于脚本的问题，这个脚本在实际的图表中切割了几个小时的时间。现在我想在每个条形图上放一个延迟，这样我的图表中就有一个时间偏移。

我试着这样做了，但是没有成功（就像我想的那样）。

你为什么不在写入文件 之前简单地在rate.time 中加入一些时间偏移（加法可以是正的或负的），然后，当你把文件写入时，再恢复它的原始值呢？

MrWigglesworth 这里有一个将DEMA添加为类型4的版本：ma__dema_crossover_with_arrow_and_email.mq4

你好，MLaden先生。

你今天好吗？附上一张带有5和12DEMA指标的图表。图表上还有你修改的ma+DEMA指标。它被设置为5-ma1和12-ma2，并为两个MA选择了类型4（DEMA）......正如你可以从箭头看到的，它们似乎与线不匹配......有什么想法吗？非常感谢!

哦，顺便说一下，这是我使用的DEMA指标，如果它有帮助的话

你用什么DEMA进行比较？

提醒一下：Dema不是ema的ema，而是2 x ema和ema的ema之差。

这方面的公式甚至可以在这里找到。双指数移动平均线 - MetaTrader 5 帮助

请看上面的2631号帖子和所附的DEMA.mq4...这有帮助吗？

是的，我对DEMA很熟悉，尽管没有记住公式......这里是5-SMA（红色）和5-DEMA（绿色）之间的实际区别。
