"Floating PositionSelect()错误
我很不好意思地问，你怎么能这么肯定有错误呢？还是你认为开发商就像泰加森林一样密集？;-)
阅读异步操作手册。

读取异步操作。
亲爱的先生，我建议你阅读帖子的开头。
我问的是如何为开发者建立一个证明基础，而不是如何使用
异步函数!
以前的构建（在对冲之前）没有这个错误。

来自MQL5的帮助
Один торговый запрос, отправленный из терминала вручную или через торговые функции OrderSend()/OrderSendAsync(), может порождать на торговом сервере несколько последовательных торговых транзакций. При этом очередность поступления этих транзакций в терминал не гарантирована, поэтому нельзя свой торговый алгоритм строить на ожидании поступления одних торговых транзакций после прихода других. Кроме того, транзакции могут потеряться при доставке от сервера к терминалу.
如果不是因为最后一句话，这并不重要。
如果TRADE_TRANSACTION_HISTORY_ADD 事件首先发生，并且TRADE_TRANSACTION_DEAL_ADD
事件丢失:(，之前的位置数据仍然会 "挂 "在终端上！)。

胡说八道。缓存（存放请求的位置数据）与交易之间有什么联系？
prostotrader，算法的逻辑一定有问题。我想翻看一下别人的代码，但我不屑一顾。我本来想挖掘一下别人的代码，但我没有勇气。

你读过你所写的东西吗？
总有一个 "老师 "自己不能做什么，但...
定期写...
他看到一个熟悉的词（ORDER_FILLING_IOC）并开始玩弄。
对于你，万事通
ORDER_FILLING_IOC
Означает согласие совершить сделку по максимально доступному на рынке объему в пределах указанного в ордере.
В случае невозможности полного исполнения ордер будет исполнен на доступный объем, а неисполненный объем ордера будет отменен.

而不仅仅是把他们的脚放在柱子上以表明观点。

假设有一个成交量为2个合约的未平仓头寸。
发送了一个部分平仓的订单（第1卷），我们从服务器上得到了一个回应
在OnTradeTransaction()函数中，PositionSelect(Symbol())位置被检查，并且
