Yes it should be added instantly

Ok its exactly what I was looking for… Thanks

HistoricalTrade trade = History.FindLast(tradeLabel);

if(trade != null)
    return true; // trade is closed

RE: RE: RE: RE: RE: Check if position has already been opened and closed?

Thanks… so as soon as a trade is closed it is instantly added to the historical? If it's instant this solution will work…. but if there is a delay of say more than 1 second then I'll have to keep them in a list in my code.

There is no option to access closed positions. You can only access past deals through History. Nevertheless if you want the information to persist between cBot restarts, you can always save it in a file

Do you have a code example of getting a trade out of history? Can it be done using a name or id? TIA

Hi there,

You can track the closed positions using the Positions.Closed event. There you can add the closed positions in a collection as the one you posted above.

Best regards,

Panagiotis

Thanks… I don't care about the event, I need to be able to look up a history of closed/filled trades. For example before placing a trade for id XYZ123 I first need to make sure that trade id XYZ123 hasn't already been opened and closed… this is to prevent duplicate trades from occurring. And if I just add them to a collection I'll lose that collection of closed trades next time the cBot is restarted which will allow duplicate trades to occur. TIA

RE: How to find a specific pending market order?

PanagiotisCharalampous said: 

Hi there, 

Pending orders are only limit, stop and stop limit orders. A market order is not a pending order.

Best regards,

Panagiotis

MetaTrader has a way to find orders before they actually become an open position. I need to do the same with cTrader. If I put on several async market orders all at once I need to be able to check if they've been filled otherwise I get duplicates. I don't want to use callbacks. I need to be able to look them up by their custom label. Something like my example:

            foreach(Order order in SomeListOfUnfilledOrders) {           

               if(order.Label == “order123”)
                   return true;        
           }

Hi there,

cBots are based on .Net. Therefore you can only call dll files based on managed code. If your dll is based on managed code, you should be able to use it.

Best regards,

Panagiotis

Thanks for the reply. I figured that was the case. I got a DLL written in managed C/C++. I need to be able to call this DLL from the cBot. I guess the only way to do that is to create a .Net DLL proxy that will call my C++ DLL?

Check the article below. It should help 

https://learn.microsoft.com/en-us/dotnet/framework/interop/consuming-unmanaged-dll-functions

Thanks

I created a .NET DLL wrapper class that calls my unmanaged C++ DLL functions ok. I added the code below to the cBot and it compiles fine in cTrader but when I run the cBot it says it can't find the DLL even though the DLL is in the same directory?

    internal static class NativeMethods {
    
        [DllImport("Client.dll", CallingConvention = CallingConvention.Cdecl)]
        internal static extern bool connClient(uint id, char[] username, char[] password);
    }

13/08/2024 22:06:42.127 | Info | CBot instance [Client_CBOT, EURUSD, h1] started.
13-08-2024 22:06:42.908 | Error | Crashed in OnStart with DllNotFoundException: Unable to load DLL 'Client.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)

Any ideas? Do I have to use the .NET DLL wrapper… doesn't make sense to do that when cBot is built in .NET?

Make sure your dll is copied to the output directory. Check the Copy Local property and make sure is set to true

 

Thanks but can you attach a bigger screenshot? I don't know where that setting is…
