新人对MQL4和MQL5的任何问题，对算法和代码的帮助和讨论

谢谢，在循环中加入ArrayResize，向数组添加新的行，得到了想要的结果。现在我研究一下调试器)

Alex Pirate 2019.09.05 17:57 #9612

大家好！我如何从这个指标中获得或找到缓冲区的编号，以便使用iCustom？这是一个简单的PivotCustomTime指标。或者有谁有ProTrader自带的简单PivotPoint指标？

请让我知道我如何在图表上获得15秒或30秒的蜡烛？

我已经看到，最小的图表时间是PERIOD_M1。但我想有一个秒表。你能告诉我这是如何做到的吗？

请您告知如何在您的EA中写明，由MA信号打开的订单将只由反向MA信号关闭（或由一个条件），而由RCI打开的订单将只由RCI关闭（由其他条件）。

，例如，这里是条件

如果(MA>close[0])

ordersend....... BUY.....

if (RSI>70)

ordersend........BUY....

-----------------------------

1) 在这种情况下，我如何根据一个条件关闭第一个订单，而根据另一个条件关闭第二个订单？

2) 如何做到以下几点：
..... а) 不超过1个订单被打开（直到打开的订单被关闭）。

.....b)，这样每个订单都会被打开，无论是否存在未结订单（多策略）

，提前感谢。

iHighest(iLowest)是否可以应用于一个指标（如MACD、RSI）？

Igor Makanu 2019.09.07 08:33 #9619

Vladimir Baskakov:
iHighest (iLowest)能否应用于一个指标（如MACD，RSI）？

复制指标缓冲区并应用ArrayMaximum ( ArrayMinimum )

但我认为如果指标使用EMPTY_VALUE 会有问题。

你能找到一些小例子吗？
