For example: at the some time working EURUSD + GBPUSD etc.

Thank you...

Attach it to different charts with different magic numbers and it should work OK. Otherwise, judging from the code, you can have a major mixup

Thank you very much detailed info.

 

By the way can we attach any number as magic number?

Its default Magic Number is: "288"

Can i attach it: 398, 477, 501, 875 etc. ?  

 

Dear Mladen ,

May i know how can i add the opposite signal close to the code ?

extern bool oppositeSignalclose=true;


i have try it but it close on every bar .


Can you help me to see what should i need to change for the  "OrderSended" close all sell after buy / close all buy after sell .

Thank you .

  // New buy orders
  TotalBuyOrders = CountOfOrders(MagicNumberBuy);
  if(TotalBuyOrders > 0 && TotalBuyOrders < MaxTrades)
  {
    OrderSended = -1;
    LastSellPrice = FindLastOrderParameter(MagicNumberBuy, "price");

    if(LastSellPrice - Ask >= GetPipstepForStep(TotalBuyOrders + 1) * vPoint)
    {
      BLot   = GetLotForStep(MagicNumberBuy, TotalBuyOrders);
      BComment = StringSubstr(LastOrderComment, 0, StringFind(LastOrderComment, "|", 0)) + "|";
      OrderSended = SendMarketOrder(OP_BUY, BLot, 0, 0, MagicNumberBuy, BComment);
    }
  }
  // New sell orders
  TotalSellOrders = CountOfOrders(MagicNumberSell);
  if(TotalSellOrders > 0 && TotalSellOrders < MaxTrades)
  {
    OrderSended = -1;
    LastBuyPrice = FindLastOrderParameter(MagicNumberSell, "price");

    if (Bid - LastBuyPrice >= GetPipstepForStep(TotalSellOrders + 1) * vPoint) 
    {
      SLot   = GetLotForStep(MagicNumberSell, TotalSellOrders);
      SComment = StringSubstr(LastOrderComment, 0, StringFind(LastOrderComment, "|", 0)) + "|";
      OrderSended = SendMarketOrder(OP_SELL, SLot, 0, 0, MagicNumberSell, SComment);
    }
  }

Invert the call to CountOfOrders if the oppositeSignalclose is set to true (ie, something like this :

if (oppositeSignalclose)
      TotalBuyOrders = CountOfOrders(MagicNumberBuy);
else  TotalBuyOrders = CountOfOrders(MagicNumberSell);
And do the same for sell orders too

It this a reverse trade ?

I want the current trade close when opposite signal .

I find one of the code on net , but it close on each bar .

Can you help me to check is that did i insert the correct way or different things that i want .

And the candle trailing stop , i have did what you teach me on last week but still cant work .

extern bool oppositeclose=true;
if((oppositeclose && sell))closebuy();
if((oppositeclose && buy))closesell();
//|---------close

void closebuy(){
   RefreshRates();
   if(OrdersTotal()>0){
      for(int i=OrdersTotal();i>=0;i--){
         OrderSelect(i,SELECT_BY_POS,MODE_TRADES);
         if(OrderSymbol()==Symbol() && OrderMagicNumber()==magic && OrderType()==OP_BUY){
            OrderClose(OrderTicket(),OrderLots(),Bid,slippage*mt);
         }
      }
   }
}

void closesell(){
   RefreshRates();
   if(OrdersTotal()>0){
      for(int i=OrdersTotal();i>=0;i--){
         OrderSelect(i,SELECT_BY_POS,MODE_TRADES);
         if(OrderSymbol()==Symbol() && OrderMagicNumber()==magic && OrderType()==OP_SELL){
            OrderClose(OrderTicket(),OrderLots(),Ask,slippage*mt);
         }
      }
   }

Just add the data you want to be exported in the FileWrite() function parameters

I have solve the opposite close function :>

But when you free can you help to check the candle trailing stop , i still cant solve it :(
