新人对MQL4和MQL5的任何问题，对算法和代码的帮助和讨论

不过，并非如此。你需要保持跟踪的结果是

或你在OnTradeTransaction中的新函数。而如果没有位置，你应该进入。或者在buySignal或sellSignal 中写入信号，然后在OnTimer中处理，就像我在例子中展示的那样。

ClosePosWithMaxProfitInCurrency

这个功能已不再适用。这是不合适的。取而代之的是，我们需要替代将先关闭一个已开订单的函数，如果它存在的话。

我不明白写在全局范围内的buySignal和sellSignal 变量。但是，当我试图编译它时，它给了我以下错误

'sellSignal' - some operator expected   

expression has no effect        

'buySignal' - some operator expected    

expression has no effect

下午好。

我当然读过这些，我可以分别写出每个订单，但问题是要缩短代码。

Shockeir 2022.01.18 09:06 #18643

各位同事下午好！请教一位新手，如何获得指标的当前值（此刻），而不是从上一栏中获得？专家顾问只在前一栏结束时触发，而我需要它更早。

到底是什么原因导致代码缩短不成功？

同事们好，请教一下新手，如何获得指标的当前值（此刻），而不是前一栏的值？EA只在前一栏结束时触发，而我需要它更早。

也许更详细地描述情况以及什么对你不起作用会更有帮助。

Shockeir 2022.01.18 09:38 #18646

Andrey Sokolov #:

也许更详细地描述情况和你自己无法做到的事情会产生更多的结果。

该指标是一个标准的随机指数。专家顾问应该在K线和D线的交汇处触发。在非常大的交叉点上，直到出现一个新栏，什么都没有发生。当一个新的条形图出现时，如果条件仍然得到满足，那么就会发生行动。据我所知，这是因为指标缓冲区中的最后一个值是在最后一个完成的条形图上计算的值。因此，我希望触发发生在一个未完成的酒吧。

该指标是一个标准的随机指数。专家顾问应该在K线和D线的交汇处被触发。在十字路口，直到出现一个新的横杠，什么都没有发生。一旦有新的柱状物出现，如果条件仍然得到满足，就会发生行动。据我所知，发生这种情况是因为指标缓冲区中的最后一个值是在最后一个完成的条形图上计算的值。因此，我希望在一个未完成的条形图上触发这个动作。

最后一根蜡烛的指数为0。

那么，你是如何尝试解决这个问题的呢？你读过帮助吗？究竟是什么原因造成的不成功？

你能把代码放进去吗？至少要清楚地说明你使用的是什么语言。

你不能再使用这个功能。它并不适合。如果这个函数存在，它应该被先关闭一个已开订单的函数所取代。

我不明白在全局层面规定的变量buySignal和sellSignal。但是，当我试图编译它时，它给了我以下错误

'sellSignal' - some operator expected   

expression has no effect        

'buySignal' - some operator expected

你是如何注册的，编译器在哪里干涉？我无法猜测。你需要源代码来了解它。
