只有当符号不在市场观察中时才需要睡眠。对于在指标之前（和期间）处于市场观察中的所有符号，不需要滑点。

我明白了。

OrderSend 花了345毫秒，而相应的订单和交易在历史上也花了26毫秒才变得可用。即一个非常缓慢的同步，我以前从未见过。

我最近在我的真实账户上得到了同样的错误。我试着下了一个订单，但服务器没有执行它。

我目前正在与一家非常知名的公司的技术支持进行沟通。(此刻我正在和一家非常知名的公司L的技术支持聊天(我们的通信是保密的，我就不这么叫了)，他们解释说他们的服务器的执行时间对于从MT4发出的订单是一样的，他们有MT4，有FIX订单，大约是1-6ms。然后，我问他们，从MT4交易时，40-50毫秒的时间是什么，因为从发送订单到得到答复的时间大约是40-60毫秒。他们宽容地耸耸肩，好像在寻找网络延迟，我告诉他们ping 1-2ms，他们又耸耸肩。结论是，MT4/5的服务器部分很慢。现在新的日志显示。我理解时间不可能像FIX那样 "干净"，但至少应该有相同的顺序。

目前我正在与洛杉矶一家非常有名的公司的技术支持人员交谈。(我不知道为什么我不给他们打电话，他们解释说在他们的交易服务器上的执行时间与从MT4（他们有MT4）发出的订单相同，由FIX发送，大约是1-6ms。然后，我问他们，从MT4交易时，40-50毫秒的时间是什么，因为从发送订单的那一刻起，得到的答案是40-60毫秒。他们宽容地耸耸肩，好像在寻找网络延迟，我告诉他们ping 1-2ms，他们又耸耸肩。结论是，MT4/5的服务器部分很慢。现在新的日志显示。我理解时间不可能像FIX那样 "干净"，但至少应该有相同的顺序。

在L...铭记，当他们收到订单进入他们的系统时，系统本身的执行时间和送回的时间可以忽略不计。他们可以从MT4服务器或通过FIX和他们的其他API获得订单。MT4服务器本身会花费几十毫秒进行内部处理，这与执行没有任何关系。

曾几何时，MT4的最小时间是150ms。似乎有什么东西被严重调整了，因为它已经变成了40-60。但MT5明显更快。现在我可以在日志中看到服务器工作了多少时间。剩下的就是要了解主要时间花在什么地方。

@Slawa，请澄清一下，在OnCalculate()函数之外写入指标缓冲区是否有任何限制？如果在OnTimer()、OnBookEvent()、OnChartEvent()等函数中写入缓冲区，一切都会正确写入吗？
