Mql4 code to check if current order has been closed

[mahlon84]

Hey guys,

I need help on coding an order should only be opened between the start of the hour and 30 minutes into the hour. If it closes within 30 minutes due to take profit or stop loss it should not open another order until the beginning of the next hour and end of 30 minutes. And so on. Anyone out there who can help on this please.

• Usually people who cannot code do not receive free help on this forum.
  
• If you show your attempts and describe your problem clearly, you will most probably receive an answer from the community. Use the CODE button (Alt-S) when inserting code.
  
• If you do not want to learn to code, that is not a problem. You can either look at the Codebase if something free already exists, or in the Market for paid products (also sometimes free).
• Finally, you also have the option to hire a programmer in the Freelance section.

2. When in doubt, think.

   void OnTick(){
       datetime now=TimeCurrent();  static datetime beginTrading=0;
       if(beginTrading > now) return        // Wait for the next half hour.
   
       if not trade condition return
       OrderSend
   
        int ps=PeriodsSecond(PERIOD_M30);   // 1800 second
        datetime halfHour = now - now % ps; // Last half hour.
        beginTrading=halfHour + ps;         // Wait for the next half hour.
   }

   Your post's title doesn't match your question. “Current order” and “closed” in the same sentence makes no sense. Just count your open orders.

         #ifdef __MQL4__
   enum TradeOperation{          // Same as OP_xxx except a proper enumeration.
         eTO_BUY, eTO_SELL, eTO_BUYLIMIT, eTO_SELLLIMIT, eTO_BUYSTOP, eTO_SELLSTOP,
         eTO_BALANCE,                         ///< (6) May occur in history pool.
         eTO_CREDIT};                         ///< (7) May occur in history pool.
   #define ENUM_ORDER_TYPE TradeOperation // Override MT4 compiler.
         #endif
   
   int count_orders(int mn=EMPTY, ENUM_ORDER_TYPE op=WRONG_VALUE){
      return count_orders(_Symbol, mn, op);
   }
   int count_orders(string symbol, int mn=EMPTY, ENUM_ORDER_TYPE op=WRONG_VALUE){
      int count=0;
      for(int i=OrdersTotal(); --i >0;) if(
         select_order(iPos, SELECT_BY_POS)
      && (OrdeMagic() == mn || mn==EMPTY)
      && (OrderType() == op || op==WRONG_VALUE)
      && OrderSymbol() == symbol
      ) ++count;
      return count;
   }
