How to delete pending order?

 

Hi: I have this first loop which scans for open orders and pending orders.  If there is an open order and a pending order, I want to delete this pending order.  What codes should I use below?

int PosTotal=PositionsTotal();
   int pnd=0,opn=0;
   
   for(int i=PosTotal-1; i>=0; i--)
      if(PositionGetSymbol(i)==Symbol())
         if(MagicNumber==PositionGetInteger(POSITION_MAGIC))
            if(PositionGetInteger(POSITION_TYPE)>1)pnd++;else opn++;

   if(opn>0 && pnd>0){
      for(int i=PosTotal-1; i>=0; i--)
      if(PositionGetSymbol(i)==Symbol())
         if(MagicNumber==PositionGetInteger(POSITION_MAGIC))
            if(PositionGetInteger(POSITION_TYPE)>1){//<----------------- then, I want to delete this pending order
   
   
   }

thanks!:-)

Ive tried this but doesnt work

for(int i=PosTotal-1; i>=0; i--)
      if(PositionGetSymbol(i)==Symbol())
         if(MagicNumber==PositionGetInteger(POSITION_MAGIC))
            if(PositionGetInteger(POSITION_TYPE)>1){
               ulong tkt=OrderGetTicket(i);
               CTrade *trade=new CTrade;
                trade.OrderDelete(tkt);
               
            }
 

If I had wanted to delete all pending orders on symbol which has already had a position I would have made something like this. 

#include <Trade\Trade.mqh>
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void OnStart()
  {
   if(PositionSelect(Symbol()))
     {
      int ord_total=OrdersTotal();
      for(int i=ord_total-1;i>=0;i--)
        {
         ulong ticket=OrderGetTicket(i);
         if(OrderSelect(ticket) && OrderGetString(ORDER_SYMBOL)==Symbol())
           {
            CTrade *trade=new CTrade();
            trade.OrderDelete(ticket);
            delete trade;
           }
        }
     }
//---
   return;
  }

I tried your code, didnt work, its not even entering the loop to print.  Im working on the code from this article: https://www.mql5.com/en/articles/59. the code+yours is below. many thanks for your help, alex.

void OnTick()

   if(time2trade(Hr,MagicNumber))

         MqlTradeRequest BigDogBuy;
         MqlTradeRequest BigDogSell;

         // Set the pending order
         BigDogBuy.magic = MagicNumber;
         BigDogBuy.symbol=Symbol();
         BigDogBuy.price=SymbolInfoDouble(Symbol(),SYMBOL_ASK)+Price*Point();
         //Price by which the order will be set
         BigDogBuy.volume=Lots;
         BigDogBuy.sl=BigDogBuy.price-TrailingStop*Point();

An Example of a Trading Strategy Based on Timezone Differences on Different Continents

Surfing the Internet, it is easy to find many strategies, which will give you a number of various recommendations. Let’s take an insider’s approach and look into the process of strategy creation, based on the differences in timezones on different continents.
 

Did you manage to figure out how to delete all the pending orders for a symbol? I'm trying to do the same and the code suggested above doesn't seem to work for me.

Cheers

Try this one, see if this works, and always check for error :

   MqlTradeRequest req = {0};
   MqlTradeResult  res = {0};

   int orders = OrdersTotal();
   req.action = TRADE_ACTION_REMOVE;

   for(int i = orders - 1; i >= 0 ;i--)
     {
     req.order  = OrderGetTicket (i);
      if (OrderGetString(ORDER_SYMBOL) == _Symbol)
        {
        ResetLastError();
        if(!OrderSend(req,res))
          {
           Print("Fail to delete ticket ",req.order  ,": Error ",GetLastError(),", retcode = ",res.retcode);
          }
        }
     }

With little effort we can correct alexvd's code below. BTW I didn't compile nor check this code below.

#include <Trade\Trade.mqh>
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void OnStart()
  {
   int ord_total=OrdersTotal();
   if(ord_total > 0)
     {
      for(int i=ord_total-1;i>=0;i--)
        {
         ulong ticket=OrderGetTicket(i);
         if(OrderSelect(ticket) && OrderGetString(ORDER_SYMBOL)==Symbol())
           {
            CTrade *trade=new CTrade();
            trade.OrderDelete(ticket);
            delete trade;
           }
        }
     }
//---
   return;
  }

Great thanks, thats works.
 
good one
 

hmm, why create a new Trade object in every for-loop?

 
Alexey Da:

If I had wanted to delete all pending orders on symbol which has already had a position I would have made something like this. 

Thanks

Good code. To make the system work more efficiently, lets make the trade declaration is done just once in a global area.
