MT4 MetaTrader4中基於時間的輸入信號

Question

有沒有人有任何關於如何在Metatrader 4中生成基於時間的輸入信號的示例代碼？例如在每天的特定時間和小時分鐘

Answer 1

我一直就在這樣一個功能。它必須進行定製 - 我正在努力製作更通用的版本;它將會非常繁瑣，需要自己的include文件。但值得一提的是，它可以在不改變代碼的情況下將其粘貼在不同的圖表上。這基本上是一個大案例陳述，我已經在這裏爲每個單獨的時間段定製了。

你在做什麼？感謝您對時間和外匯的興趣！

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()爲您提供自本地計算機（終端客戶端）1970年1月1日午夜起的秒數。

TimeCurrent()給出自您經紀商計算機（服務器）1970年1月1日午夜以來的秒數。

您可以對這些轉換爲字符串，像這樣：

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

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

您還可以得到像這樣的日期數字的各個元素：

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

希望這會有所幫助。
