构建1485之后，对CopyTicks()和CopyTicksRange()的缺陷和改进建议。

[删除] 2017.02.23 03:36 #31

Yury Kirillov:
尝试在你的专家顾问中使用所有可能的方式来接收ticks和OnTick以及CopyTicks，然后比较结果并使用最合适的方式。

而OnTick()与此有什么关系？它的目的不是接收所有蜱虫，而是为了处理收到蜱虫的事实。你甚至不需要在这里做任何比较，OnTick()不会在每个tick被调用，它不允许接收MqlTick结构的所有数据。

服务台提出在新的建筑1545上进行尝试。但是结果并没有改变，就像以前一样，为一些文件请求从上午10点到11点的刻度，返回的是零数组，然后由于某种原因，数据从11点开始进来。也许在那之后，在查询时蜱虫已经 "正常 "了，但没有任何关联性。

antru 2017.03.09 07:16 #33

这几乎是他们发出的唯一信息。已经有相当长一段时间了，服务台没有回应。无视我的信息是否正常？

关于无视你的信息--你有错误的分支。关于SD，有一个单独的主题。事实上，通过在申请书上写下评论来提醒他们。你是否向BOD附上了代码和其他证据？

Alexey Kozitsyn:

是的，当然，甚至解释了代码...沉默...谢谢你的提示，我将把它放在一个单独的主题中

antru 2017.03.16 06:23 #36

制作了调试代码来检查CopyTicksRange。虽然服务台长期处于沉默状态，但我想知道代码中是否有错误。我的眼睛一定是瞪大了......。请用新的眼光来看待它。

下面是代码，请附上结果。第一个压缩包--在交易前开始Metatrader，第二个压缩包--在美国东部时间晚上10:30开始（调试文件中的时间少了3小时）。

我不明白为什么在第一轮观察中，任何纸张上都没有蜱虫回来。

在所有。乡亲们，你们是如何实时获得磁带的呢？也许我在重新发明轮子，做错了什么，你能给我一个例子代码，说明如何实时获得文件上的刻度吗？
