MQL5 如何每天只开一个仓位

Question

我的意思是，如果专家在一天中的任何时间开仓，此后就不要在当天开仓

我尝试用这种方法检查这一点，并在开新仓之前将其入池，但它不起作用

bool IsOneDayPassedSinceLastDeal（字符串符号） {

int totalDeals = HistoryDealsTotal();


if (totalDeals == 0)
    return true;


for (int i = totalDeals - 1; i >= 0; i--)
{
  
    ulong dealTicket = HistoryDealGetTicket(i);

    
    string dealSymbol = HistoryDealGetString(dealTicket, DEAL_SYMBOL);

    if (dealSymbol == symbol)
    {
        datetime openTime = HistoryDealGetInteger(dealTicket, DEAL_TIME);

        datetime currentTime = TimeCurrent();

        int timeDifference = currentTime - openTime;

        int secondsInDay = 24 * 60 * 60;

        if (timeDifference < secondsInDay)
            return false;
    }
}

// If no deal was found for the symbol within the last day, return true
return true;

}

解决方案编辑此方法

bool IsOneDayPassedSinceLastDeal() {

MqlDateTime currentDate;
TimeCurrent(currentDate);

int currentDay = currentDate.day;

int lastDay = _lastPositionTime.day;
 
if (currentDay == lastDay ) {
    return false; 
} else {
    return true; 
}

}

定义 MqlDateTime _lastPositionTime； 作为公共变量
