Nguyen Nga:

your pending triggered, it become Positions.

then you must use PositionSelectByTicket to check, not use HistoryOrderSelect.


 I have a similar issue but slightly different. It occurs occasionally during fast moving market. I notice a open pending order that could't be deleted by EA and the market have passed that price. When i try deleting it manually is say ''invalid '',but when i restart MT4 it appears to be an open position. Can any help me or i'm experiencing the same issue ?


This code creates new pending Orders

if( rateChange > VelocityTrigger * Point && avgSpread <= maxSpread && totalBuyStop < TradeDeviation ) {
         if( AccountFreeMarginCheck( Symbol(), OP_BUY, lotSize() ) <= 0 || GetLastError() == 134 ) {
            Print( "Notice: Not enough free margin to open trade. Expert is removed." );
            ExpertRemove();
            return ( 0 ); 
         }
         ticket = OrderSend( Symbol(), OP_BUYSTOP, lotSize(), Ask + ( totalBuyStop + 1.0 ) * ( Point * TradeDelta ), Slippage, 0, 0, TradeComment, MagicNumber, 0 );
      } 
      if( rateChange < - VelocityTrigger * Point && avgSpread <= maxSpread && totalSellStop < TradeDeviation ) {
         if( AccountFreeMarginCheck( Symbol(), OP_SELL, lotSize() ) <= 0 || GetLastError() == 134 ) {
            Print( "Notice: Not enough free margin to open trade. Expert is removed." );
            ExpertRemove();
            return ( 0 );
         }
         ticket = OrderSend(Symbol(), OP_SELLSTOP, lotSize(), Bid - ( totalSellStop + 1.0 ) * ( Point * TradeDelta ), Slippage, 0, 0, TradeComment, MagicNumber, 0 );

      }   




This code check for order status

case OP_BUYSTOP:
               if( avgSpread > maxSpread ||  MathAbs( rateChange ) < VelocityTrigger * Point  ) 
                  r = OrderDelete( OrderTicket() );
               totalBuyStop++;
            break;
            case OP_SELLSTOP:
               if( avgSpread > maxSpread ||  MathAbs( rateChange ) < VelocityTrigger * Point  ) 
                  r = OrderDelete( OrderTicket() );
               totalSellStop++;
            break;

Please don't hijack old (and not related) topic. Thanks.

  2. ticket = OrderSend( Symbol(), OP_BUYSTOP, lotSize(), Ask + ( totalBuyStop + 1.0 ) * ( Point * TradeDelta ), Slippage, 0, 0, TradeComment, MagicNumber, 0 );

  3. Pending order, once open, becomes buy/sell. You can't delete opened orders, they must be closed. The code you state "check for order status" is without context. We have no idea wether or how you selected the order before using OrderTicket.
