MT5和速度在行动

A100:
自然，没有专家/指示器/脚本在运行--只有手动构建。所示的延迟在任何普通的现代64位平板电脑上都是可重复的。如果你有一台i7电脑，我想你不会遇到这种延迟。

是apk还是exe系统变慢了？

在另一个终端，优化是在可能的八个本地代理中的六个上并行运行。

如果这些是网络中断，为什么会影响到从市场观察中获得最后一个刻度，以及从刻度历史中获得最后一个刻度？

首先，仅供参考。

"如果基本结构检查（指针检查）成功，则返回true--它并不表示交易操作 的成功执行。为了获得对函数执行结果的更详细描述，应该对结果结构的字段进行分析。"

其次，根据你的逻辑，如果一个订单被打开，你不会把它添加到订单列表中，而是完全使缓存失效）？

你可以通过优化所有的代码，你有历史选择将是执行时间问题的最后一个地方）使用缓存。你可以让它失效，例如，每天一次，但这将大大加快你的EA速度。

fxsaber 2020.09.07 09:37 #245

Andrey Pogoreltsev:

嗯，首先

你要么必须运行代码来正确理解它，要么从工作表中很好地阅读它。

第二，按照你的逻辑，如果一个订单被打开，你不会把它加入到订单列表中，而是完全使缓存无效）？

订单列表没有变化。阅读代码。

Artyom Trishkin 2020.09.07 09:53 #246

fxsaber:

为了正确理解代码，你必须运行它，或者从工作表中很好地阅读它。

订单的清单不会改变。阅读代码。

这里

if (OrderSend(Request, Result))
    _B2(HistorySelect(0, INT_MAX)); // В каком месте самострел?

我看到这个逻辑。

如果交易请求被成功发送到服务器上
我们选择整个历史

但也可能是该请求已经在服务器上被拒绝了--在这段代码中没有对此进行检查。选择历史的意义何在？我们想在那里看到什么？

在这里，在这两行代码中，我个人不认为有什么意义。如果在选择故事之前有一个检查来改变它，我就会看到。当然，也许这两行并不能给你一个完整的任务图。但我不清楚成功向服务器发送请求和选择整个历史记录之间的联系。即使服务器成功发送了请求，市场订单和头寸的列表也会被改变。历史名单与此有什么关系？

fxsaber 2020.09.07 10:30 #247

Artyom Trishkin:

这里是

我看到这个逻辑。

如果 - 摆脱了编译器警告。它没有别的事可做。

这个主题不是用来教你如何编写EA的。其目的是为了消除终端的弱点。开发人员需要一个简单、简明、可复制的代码来理解它。当然，我并不是为自己写这种东西。事实是，战斗顾问记录了刹车的情况。我开始挖掘，发现当有人（至少是用手）修改一个位置时，速度就会变慢。这就重置了历史缓存，当然，历史不会改变。

这段代码完美地演示了这个问题。从来没有必要用任何不必要的检查来扰乱重放的代码。它的工作是明确显示问题。而当修复后--证明现在一切工作正常。

Andrey Pogoreltsev 2020.09.07 10:36 #248

fxsaber:

为了正确理解代码，你必须运行它，或者从工作表中很好地阅读它。

订单的清单不会改变。阅读代码。

考虑到我非常善于照本宣科 :)

这段代码是你从别的地方拿过来的，你在那里有一个新的位置的创建，它被执行，对吗？

否则，你的代码的全部意义就归结为更新当前位置的TP，并为了它而使缓存失效，这也是非常奇怪的。

在这两种情况下，都没有使用逻辑来优化缓存操作。此外，你的解决方案是不可扩展的，因为它导致了随着历史的增长而增加的制动。

Andrey Pogoreltsev 2020.09.07 10:40 #249

fxsaber:

这段代码完美地证明了这个问题。从来没有必要用任何不必要的检查来扰乱重放代码。它的工作是明确显示问题。并在纠正后--证明现在一切工作正常。

所以根据你的逻辑，这里的代码

int v = 0.0;

for (int i = 0; i < 1000000; i++) {
    v = i;
}

std::cout << "The last number: " << v << std::endl;

证明了处理器的迟钝？

fxsaber 2020.09.07 10:40 #250

Andrey Pogoreltsev:

你从某个地方得到了这段代码，你通过创建一个新的位置把它放在那里，这确实得到了执行，对吗？

反问：你在这里想达到什么目的？

Andrey Pogoreltsev:

所以，按照你的逻辑，这里的代码

显示处理器速度慢？

我不会再回答了，因为你在胡说八道。
