我仅出于策略测试者的目的而编写EA，以评估投资组合。因此，我在阵列中有成千上万的交易，包括开盘价格和开盘时间，每隔1分钟一格，我会在for循环中检查该分钟是否有任何交易要开放。而且这是永远的。
如何检查（以更快的方式）数组中是否存在与当前时间一致的开放时间？
谢谢！

最简单的方法是使用类，每个类都扩展CObject，并且您必须实现Compare函数。
首先，创建一个进入（in = true）和退出（in = false）的结构：
struct SEvent
{
datetime m_time;
double m_price;
bool m_in;
void Init(const datetime time,const double price,const bool in)
{
m_time=time;
m_price=price;
m_in=in;
}
int Compare(SEvent &another)const
{
return int(m_time-another.m_time);
}
};
接下来，创建类CDeal : public CObject
class CDeal : public CObject
{
static int getDir(string cmd)
{
if(cmd=="Sell")
return(-1);
if(cmd=="Buy")
return(1);
if(cmd=="Type" || cmd=="Balance")
return(0);
printf("%i %s: unknown cmd=|%s|",__LINE__,__FILE__,cmd);
return(0);
}
static string getSymbol(string line)
{
return StringSubstr(line,0,StringLen(line)-StringLen(InpReportSuffix))+InpSymbolSuffix;
}
public:
intX m_id;
int m_dir;
SEvent m_in;
SEvent m_out;
double m_lot;
string m_symbol;
double m_osl;
double m_otp;
CDeal(string line)
{
//2019.05.13 18:27:56;Sell;0.10;EURCADm#;1.51270;;;2019.05.14 13:36:47;1.51142;;;0.10;
string array[];
const ushort separator=(ushort)';';
int size=StringSplit(line,separator,array);
if(size<11)
{
printf("%i %s: size=%d str=%s",__LINE__,__FILE__,size,line);
m_dir=0;
return;
}
m_dir=getDir(array[1]);
m_lot=StringToDouble(array[2]);
m_symbol=getSymbol(array[3]);
m_in.Init(StringToTime(array[0]),StringToDouble(array[4]),true);
m_osl=StringLen(array[5])>0 ? StringToDouble(array[5]) : 0;
m_otp=StringLen(array[6])>0 ? StringToDouble(array[6]) : 0;
m_out.Init(StringToTime(array[7]),StringToDouble(array[8]),false);
}
~CDeal(){}
virtual int Compare(const CObject *node,const int mode=0) const
{
CDeal *another=(CDeal*)node;
if(mode==1)
{
return m_in.Compare(another.m_in);
}
else
{
return m_out.Compare(another.m_out);
}
}
virtual string toString()const
{
return StringFormat("%s;%d;%.2f;%s;%.5f;%.5f;%.5f;%s;%.5f;%s",TimeToString(m_in.m_time),m_dir,m_lot,m_symbol,
m_in.m_price,m_osl,m_otp,TimeToString(m_out.m_time),m_out.m_price,m_pnl.toString());
}
};
然后，将CDeal中的所有string加载到CArrayObj和list.Sort(1)中，以便按输入时间对其进行排序。然后循环，从static int cursor=0;开始，如果TimeCurrent()>((CDeal*) list.At(cursor)).m_in.m_time递增，则当然要记住您可能到达列表的末尾，或者如果条件相同，则分离元素，然后附加到另一个{{1 }}。每次添加元素时，请不要忘记对现有未完成交易的列表进行排序。以同样的方式检查是否该关闭未平仓交易列表中的某些交易，并在平仓后删除元素。
