当EA交易无法关闭交易头寸时发送电子邮件通知
我正在尝试开发一段MQL4代码，当Expert Advisor打开的职位在满足EA交易指定的条件时无法关闭/清算时，会向您发送通知。
以下是我到目前为止的情况。
当成功平仓时ClosePosition()返回true，当EA未能平仓时返回false。else if (ClosePosition == false)这就是//Order Close//
string sym = Symbol();
int ordersTotal = OrdersTotal();
for(int PosSel = ordersTotal-1; PosSel>=0; PosSel--)
{
if(OrderSelect(PosSel,SELECT_BY_POS,MODE_TRADES))
if(OrderTicket() > 0)
if(OrderMagicNumber() == Period())
if(OrderSymbol() == Symbol())
if(TimeCurrent() >=(OrderOpenTime() + 60 * Period()))
{
ClosePosition = OrderClose(OrderTicket(),8,MarketInfo(sym,MODE_BID) + MarketInfo(sym,MODE_SPREAD) * MarketInfo(sym,MODE_POINT),300,clrNONE);
if(ClosePosition == true)
{
Sleep(60000);
int PosSelHist = OrdersHistoryTotal()-1;
bool reshist = OrderSelect(PosSelHist,SELECT_BY_POS,MODE_HISTORY);
if(reshist == true && Digits == 5)
{
double ClosingPrice = OrderClosePrice();
double OpeningPrice = OrderOpenPrice();
double Profit = OrderProfit();
int Ticket = OrderTicket();
SendMail("Trade Notification Email (TNE)","Order# "+DoubleToStr(Ticket,0)+" has been closed on the account "+AccountName()+
"\n"+
"\nThe order exit price for this trade is "+DoubleToStr(ClosingPrice,5)+"with a profit/loss of"+DoubleToStr(Profit,2)+
"\n"+
"\nThe spread charge for this position is £"+DoubleToStr((spread*tickvalue)*LotSize,2)+
"\n"+
"\n-----------------------------------------------------------------------"+
"\n"+
SendNotification("Ticket # "+IntegerToString(Ticket,10)+"has closed with a profit/loss of "+DoubleToStr(Profit,2));
}
else if(reshist == true && Digits == 3)
{
double ClosingPrice = OrderClosePrice();
double OpeningPrice = OrderOpenPrice();
double Profit = OrderProfit();
int Ticket = OrderTicket();
SendMail("Trade Notification Email (TNE)","Order# "+DoubleToStr(Ticket,0)+" has been placed on the account "+AccountName()+
"\n"+
"\nThe order entry price for this trade is "+DoubleToStr(ClosingPrice,3)+"with a profit/loss of"+DoubleToStr(Profit,2)+
"\n"+
"\nThe spread charge for this position is £"+DoubleToStr((spread*tickvalue)*LotSize,2)+
"\n"+
"\n-----------------------------------------------------------------------"+
SendNotification("Ticket # "+IntegerToString(Ticket,10)+" has closed with a profit/loss of "+DoubleToStr(Profit,2));
}
}
else if(ClosePosition == false)
{
int failedClosePosition = OrdersTotal()-1;
bool fail = OrderSelect(failedClosePosition,SELECT_BY_POS,MODE_HISTORY);
if(fail == true)
{
SendNotification("Order Number #"+IntegerToString(OrderTicket(),10)+" has failed to close. Please refer to error code "+IntegerToString(GetLastError()));
}
}
}
}
开始的地方。
ClosePosition == true首先，这是获得理想结果的正确方法，其次;这是对if替代方案进行编码的正确方法，还是else if而不是compile files('libs/lucene-6.2.0/queryparser/lucene-queryparser-6.2.0.jar')
compile files('libs/lucene-6.2.0/demo/lucene-demo-6.2.0.jar')
compile files('libs/lucene-6.2.0/core/lucene-core-6.2.0.jar')
compile files('libs/lucene-6.2.0/analysis/common/lucene-analyzers-common-6.2.0.jar')

不，抱歉。代码很难被证实是正确的。
当然，可以修复一些语法错误。
很大一部分处理是重复的，这可能有效，但很难长期维护，并被认为是一个糟糕的软件工程实践/习惯。
您可能会受益于相当保留搜索OrderTicket()然后直接db.POOL后的唯一SELECT_BY_TICKET值，这对{ MODE_TRADES | MODE_HISTORY } db.POOL部分Sleep( 60000 )部分中的所有order_state / order_relative_position更改都很有效
接下来是提议的MQL4代码的最大敌人：
如果有人相信这一点，永远不会阻止代码的流动。 MQL4代码执行环境是基于事件的，由外部事件源（市场）触发，调用Sleep()比在EuroTunnel退出时在轨道上休眠更糟糕。 OUCH !!
您的代码无法做出反应，更糟糕的是，无法让MQL4代码生态系统的其他部分与市场事件流同步呼吸。相信我，肯定有更好的方法，如何“几乎不做”，而不是Digits。
效率提示：
避免代码重复，而是使用StringFormat() - 特定的格式，无论是通过设置为实际小数位数的变量，还是通过OrderTicket()模式。
可能会享受一些不同的代码布局，这将有助于您避免语法错误，错过括号等。
更喜欢使用全球唯一的，与指针类似的OrderClose()数字，如OrderClose()中所评估，而是预先存储它的值，因为您希望稍后在代码中重复使用它，但是没有从if(){}else if(){}时刻获得它。
可以享受另一个用于MQL4代码工作的IDE，其中折叠和柱状块变得非常方便（Geany，SciTe，JEdit，Notepad ++）。在这里，您很快就会在{True|False}代码中查看效率低下的情况-blocks，其中else部分重复了自然的共同//Order Close//

- 二分法。
无论如何，享受MQL4的狂野世界

您可能会尝试平仓，但由于一些常规问题而失败 - 重新报价，或交易环境繁忙或其他情况。 因此，您必须确保收盘价是新鲜的
RefreshRates();
您也可以尝试解决TradeContext问题和其他方式，替代方式 - 尝试发送一些关闭请求：
int ATTEMPTS; // declare on a global scope
int OnInit(){ // initialise
ATTEMPTS = IsTesting() ? 1 : 100; // ternary-op =boolA?valB:valC
//---
return(INIT_SUCCEEDED);
}
void Order_Close(){
int ticket = GetTicketNumberToClose(); // put all checks here
TradeClose(ticket);
}
void TradeClose(int ticket){ // change to bool
// returning T/F if you need
while(IsTradeContextBusy()) Sleep(5); // a blocking-loop
int current_attempt = 0, err=-1;
while(current_attempt < ATTEMPTS){
RefreshRates(); // get fresh prices from Market
if (!OrderClose(ticket,OrderLots(),OrderClosePrice(),5)){
err = GetLastError();
current_attempt++;
}else return;
}
Print( __LINE__,
"failed to close ticket#", ticket,
" at price", DoubleToStr( OrderClosePrice(), Digits ),
". err#", err
); // send notification
// instead of Print() if you need
}
