Order execution error

Hi,

I have backtested a robot and orders have been placed and trades executed as expected.

While testing the robot for a week real time, the robot tried to place 2 orders. Neither were successfull. The platfrom showed a feedback box stating:

" Order Request Your request to BUY LIMIT ... is being placed" (should be attached to this thread)

The platfrom then locked up and no messages (Print()) after that time were written to log.

When I closed the platfrom a further message box poped up just for a second stating:

"Order execution error".

Here is the code that places the order:

private void placeOrder()
			{
			// If all conditions of LONG trades have been met
			if (FlatLongShort == 1 && orderPlaced == false)
				{					
				// Calculate the Volume
				int lots = (int)(Risk/riskInPips);
				lots = lots/10000; lots = lots*10000; // Round off using integer truncation
				Volume = lots;
				// Adjust entry if we are looking for a BetterEntry
				double entry = targetPrice - (BetterEntry/10000); 				
				Trade.CreateBuyLimitOrder(Symbol,Volume,entry,SL,TP,null); 				
				orderPlaced = true;				
				}
			// If all conditions of SHORT trades have been met
			if (FlatLongShort == 2 && orderPlaced == false)
				{										
				// Calculate the Volume
				int lots = (int)(Risk/riskInPips);
				lots = lots/10000; lots = lots*10000; // Round off using integer truncation
				Volume = lots;
				// Adjust entry if we are looking for a BetterEntry
				double entry = targetPrice + (BetterEntry/10000);					
				Trade.CreateSellLimitOrder(Symbol,Volume,entry,SL,TP,null);			
				orderPlaced = true;				
				}
			}
		

[Background:

The logic whether an order should be placed is calculated elsewhere, OnBar
SL,TP etc are calculated elsewhere.

The above

placeOrder()

is called OnTick if a certain Bid/Ask price is reached.

However, the important point here is that the robot tries to create a Limit BUY/SELL order close to market price. Worked back testing, but not in real time.]

I have now added the following code to track the error, but it is unlikely that I will be able to read any error messages as the platform locks up and nothing will then be written to log:

protected override void OnError(Error error)
		{		
			Print("There has been an Error");
			switch (error.Code)
            {
                    case ErrorCode.BadVolume: Print("Bad Volume");
                    break;
                    case ErrorCode.TechnicalError:Print("Technical Error");
                    break;
                    case ErrorCode.NoMoney: Print("No Money");
                    break;
                    case ErrorCode.Disconnected: Print("Disconnected");
                    break;
                    case ErrorCode.MarketClosed: Print("Market Closed");
                    break;
            }		 
		
		}

Does any one have any tips or hints:

- How to get more information what the Order Execution Error is

- What things cause Order Execution Errors (it does not necessarily come from the robot. It could be a platform or Internet problem)

- Any ideas?

Thanks for reading this and your advice,
