Hi noorimotlagh.reza,

Here it is 

            foreach (var position in Positions.Where(x => x.SymbolCode == Symbol.Code))
            {

            }

Best Regards,

RE: choose specific Symbol or Symbols

Dear Panagiotis,

I currently use version 3.0 cTrader. After running this code, The cTrader genarates the following error.

Code:

foreach (var position in Positions.@where(x => x.SymbolCode == "EURUSD"))

Error:

Error CS1061: 'cAlgo.API.Positions' does not contain a definition for 'where' and no extension method 'where' accepting a first argument of type 'cAlgo.API.Positions' could be found (are you missing a using directive or an assembly reference?)

Thanks,

Reza

Hi Reza,

There is an @ in the code. Is this the reason? If not then make sure you reference LINQ. To do so just add

using System.Linq;

is the using section.

Hi Panagiotis,

The @ be add to the code after saving by cTrader  (I don't know why?!!?). You can see in below codes that are befor and after saving: After the build the code,  cTrader genarates this error; (Error CS1061: 'cAlgo.API.Positions' does not contain a definition for 'where' and no extension method 'where' accepting a first argument of type 'cAlgo.API.Positions' could be found (are you missing a using directive or an assembly reference?)

Befor Saveing:

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo.Robots
{

    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class CVSecondEdition : Robot
    {
        protected override void OnTick()
        {

            foreach (var position in Positions.where(x => x.SymbolCode == "EURUSD"))
            {


                Print("Symbol: {0}", position.SymbolCode);
                Print("The current symbol has pip size of: {0}", MarketData.GetSymbol(position.SymbolCode).PipSize);
                Print("SL: {0}", position.StopLoss);


            }
        }
    }
}

After  Saving:

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo.Robots
{

    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class CVSecondEdition : Robot
    {
        protected override void OnTick()
        {

            foreach (var position in Positions.@where(x => x.SymbolCode == "EURUSD"))
            {


                Print("Symbol: {0}", position.SymbolCode);
                Print("The current symbol has pip size of: {0}", MarketData.GetSymbol(position.SymbolCode).PipSize);
                Print("SL: {0}", position.StopLoss);


            }
        }
    }
}

Ηi noorimotlagh.reza,

It should be Where and not where. c# is a case sensitive language.
