MetaTrader4 中的 MT4 基于时间的入场信号

Question

有谁有关于如何在 Metatrader 4 中生成基于一天中时间的入场信号的示例代码吗？例如，在每天的特定小时和分钟

Answer 1

我一直在研究这样的功能。它必须进行大量定制——我正在努力制作一个更通用的版本，它会变得又大又乏味，需要它自己的 include 文件。但能够在不更改代码的情况下将其粘贴在不同的图表上是值得的。这基本上将是一个大案例陈述，其中我已经根据每个单独的时间范围定制了内容。

你一直在做什么？感谢您对时间和外汇的兴趣！

bool existordertime( datetime time, int otype = -37 ) {
    // +---------------------------------------------------------------+
    // | this function is intended for use inside of if() and other conditionals
    // | usually called with TimeCurrent() example:
    // | 
    // | if ( !existordertime( TimeCurrent() ) )
    // | 
    // | it accepts a datetime. A datetime is:
    // | a number of seconds elapsed from 00:00 January 1, 1970
    // | they can be treated as integers as such or accessed with other functions
    // | so that if statements can be commented in and out easily based on what 
    // | timeframe we plan on looking at.
    // | there is an optional parameter for an order type if you need it.
    // | 
    // | KEEP IN MIND if you want to use this to trade something like a 5min 15min
    // | or 4hr your gonna need a lot of if statements like:
    // | 
    // | if (  MathMod( Minute() + 5, 5 ) == 0 )
    // | 
    // +------------------------------------------------------------------+
    for (int cnt = 0; cnt < OrdersTotal(); cnt++) {

        OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);

        if (OrderType() == otype || -37 == otype)

        // COMMENT OUT THE if()S YOU DON'T NEED HERE: 
        //                       also add new lines as needed
        // if (  MathMod( TimeMinute( time ) +  5,  5 ) == 0 )   //  5min chart
        // if (  MathMod( TimeMinute( time ) + 15, 15 ) == 0 )   // 15min chart
        // if (  MathMod( TimeMinute( time ) + 30, 30 ) == 0 )   // 30min chart
        // if (  MathMod( TimeHour(   time ) +  4,  4 ) == 0 )   // 4hour chart

        int dbOrderOpenTime = OrderOpenTime();                   // re-use SAVEs dbPOOL-access time ...

        if (                      TimeSeconds( time ) == TimeSeconds( dbOrderOpenTime ) )
            if (                  TimeMinute(  time ) == TimeMinute(  dbOrderOpenTime ) )
                if (              TimeHour(    time ) == TimeHour(    dbOrderOpenTime ) )
                    if (          TimeDay(     time ) == TimeDay(     dbOrderOpenTime ) )
                        if (      TimeMonth(   time ) == TimeMonth(   dbOrderOpenTime ) )
                            if (  TimeYear(    time ) == TimeYear(    dbOrderOpenTime ) )
                                return (TRUE);
    }

    for (cnt = 0; cnt < OrdersHistoryTotal(); cnt++) {

        OrderSelect(cnt, SELECT_BY_POS, MODE_HISTORY);

        if (OrderType() == otype || -37 == otype)
        // COMMENT OUT THE if()S YOU DON'T NEED HERE: 
        //                       also add new lines as needed
        // if (  MathMod( TimeMinute( time ) +  5,  5 ) == 0 )   //  5min chart
        // if (  MathMod( TimeMinute( time ) + 15, 15 ) == 0 )   // 15min chart
        // if (  MathMod( TimeMinute( time ) + 30, 30 ) == 0 )   // 30min chart
        // if (  MathMod( TimeHour(   time ) +  4,  4 ) == 0 )   // 4hour chart

        int dbOrderOpenTime = OrderOpenTime();                   // re-use SAVEs dbPOOL-access time ...

        if (                      TimeSeconds( time ) == TimeSeconds( dbOrderOpenTime ) )
            if (                  TimeMinute(  time ) == TimeMinute(  dbOrderOpenTime ) )
                if (              TimeHour(    time ) == TimeHour(    dbOrderOpenTime ) )
                    if (          TimeDay(     time ) == TimeDay(     dbOrderOpenTime ) )
                        if (      TimeMonth(   time ) == TimeMonth(   dbOrderOpenTime ) )
                            if (  TimeYear(    time ) == TimeYear(    dbOrderOpenTime ) )
                                return (TRUE);
    }

    return (FALSE);
}

Answer 2

TimeLocal() 为您提供本地计算机（终端客户端）自 1970 年 1 月 1 日午夜以来的秒数。

TimeCurrent() 为您提供自 1970 年 1 月 1 日午夜以来您的经纪商计算机（服务器）的秒数。

您可以将其中任何一个转换为字符串，如下所示：

string ct = TimeToStr(TimeLocal(),TIME_DATE|TIME_SECONDS);
Print("Client Time: ", ct);

string st = TimeToStr(TimeCurrent(),TIME_DATE|TIME_SECONDS);
Print("Server Time: ", st);

您还可以获取日期数字的各个元素，如下所示：

Print("Year:",TimeYear(TimeCurrent())," Month:",TimeMonth(TimeCurrent()));
