CYBOPOB:


好吧，如果写得人道一点就好了......开始时一切似乎都很清楚，但稍后你就会开始失去理智......））。

O.K. 一个具体的例子。


该订单在TP运动结束时被关闭，但由于卖出信号没有被取消，新的订单被打开，这是不可接受的。

我测量了720秒，之后我们可以打开一个新的订单。那么，在这种情况下，这些秒数将从哪个顺序测量，从历史上的第一个顺序还是从最后一个顺序？

然后：如果是这样，然后呢？既然我加了Z，那就从头算起吧？呵斥:))


非常感谢您!


该函数返回自上次关闭位置以来的秒数。
 

数组的长度发生了变化，我们看到它从

2013.04.08 19:06:05 2013.03.28 20:00 testavimas naktini fleta EURUSD,M15: ArraySize 21
但所有元素都以零的形式写入数组中。

2013.04.08 19:06:04 2013.03.28 16:00 testavimas naktini fleta EURUSD,M15: avgPriceC[19]=0.00000000
所以这一行没有为数组元素 分配 Close[1]值。 

avgPriceC[i] = Close[1];
谁能解释一下原因。
 

帮助

我试着通过交错变量来实现，但没有成功。ArrayResize 被放在了数组的后面。其结果是一样的。数组中存在零。

我在你的代码中没有看到int i字符串和索引的初始化。请将字符串提交给工作室。
