//Does this get what you want?

if (!obj.IsSuccessful)
{
    if (obj.Error.HasValue)
    {
        Print("Error! : {0}", obj.Error.Value.ToString();
    }
}

firemyst,

Not really. That's simply the error description.

What I want is to access to the trade operation ExecuteMarketOrderAsync() parameters, in this case to the label.
The goal is to know, exactly, which operation has failed: "Position #1" vs "Position #2".

Then you might want to try a brute force way:

//written off the top of my head, so may not work exactly as is
using cAlgo.API;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class MarketOrderTest : Robot
    {

    //we'll add the labels of the orders we place to this object:
	Dictionary<int, string> d = new Dictionary<int, string>();
    //keep track of each async trade
	bool trade1Finished = false;
	bool trade2Finished = false;

        protected override void OnStart()
        {
                                string label1 = "Position #1";
                                string label2 = "Position #2";
                                d.Add(1, label1);
                                d.Add(2, label2);
                                trade1Finished = false;
                                trade2Finished = false;
                                ExecuteMarketOrderAsync(TradeType.Buy, SymbolName, Symbol.VolumeInUnitsMin, d[1], (TradeResult r) =>
                                {
                                    if (r.IsSuccessful)
                                    {
                                        //remove from dictionary object as we know it completed
                                        if (r.Position.Label == label1)
                                            d.Remove(1);
                                    }
                                    trade1Finished = true; //done tracking this trade
                                });
                                ExecuteMarketOrderAsync(TradeType.Buy, SymbolName, Symbol.VolumeInUnitsMin, d[2], (TradeResult r) =>
                                {
                                    if (r.IsSuccessful)
                                    {
                                        //remove from dictionary object as we know it completed
                                        if (r.Position.Label == label2)
                                            d.Remove(2);
                                    }
                                    trade2Finished = true; //done. This trade finished
                                });
        }

        protected override void OnTick()
        {
        //check when both trades are done.
        //can also alter so that you check each trade individually
		if (trade1Finished && trade2Finished)
		{
                                if (d.ContainsKey(1))
                                {
                                    //error occurred with this order since key still exists
                                }
                                if (d.ContainsKey(2))
                                {

                                }
		}

        }
    }
}

firemyst,

Thanks for your reply.

What I really need is to identify the respective trade operation when trade result is not successful.

I have an auxiliary variable aux[i] that will be set to true before ExecuteMarketOrderAsync(), and I want it to be false in case trade result is not successful. However, I need to exactly know what is the applicable index "i", which can only be taken from the operation label.

I am affraid that the only way to get this done is to create several callback functions from 0 to i_max, and define multiple ExecuteMarketOrderAsync() inside a switch case, each of these with its own callback function as argument.

Hi ncel01,

I did not try it but shouldn't this work?

        private void OnTradeResult(TradeResult obj)
        {            
            if (!obj.IsSuccessful) 
                Print("Market order failed :", obj.PendingOrder.Label);
        }

Hi Panagiotis,

No, I don't think so. This was the first option I've checked, I guess.

It returns NullReference since no order/position took place. This is the problem here. Apparently, there is no way to access to the operation parameters when trade result is not successful.
