There is no difference between ‘OEW3’ and ‘OE3A’ or ‘OE4A’ And I get results for all contracts only by changing ‘private const string BaseSymbol’ in the example So, please provide additional info: At each step in the example, you are not getting data? Do you see these contracts in ‘Gain Trader Developer’ – Lookup window ? |

You can use: var client = GFApi.CreateClient(); …. var contractID = client.Contracts.Get("ESZ22")?.ID; But it can return null if the contract is not loaded from a server For guaranteed results, you still need to use: client.Contracts.Lookup.BySymbol("ESZ22"); and “SymbolLookupEventArgs event” |

It’s strange Maybe something wrong with your Nuget Installer Please check ‘basicexample\GF.BasicExample\packages.config’ It should contain: package id="GFAPI" version="4.0.3.44" targetFramework="net462" package id="Microsoft.CSharp" version="4.5.0" targetFramework="net462" package id="SimpleInjector" version="4.7.1" targetFramework="net462" package id="System.Reflection.Emit" version="4.3.0" targetFramework="net462" Also check ‘d:\projects\OEC\bitbucket\basicexample\packages’ This folder should contain: GFAPI.4.0.3.44, SimpleInjector.4.7.1, Microsoft.CSharp.4.5.0, System.Reflection.Emit.4.3.0 Edited by SPikalov on Nov 10, 2021 06:47 AM |

I can advise you the following: Send a subsequent request to contract load only after you have received a response to the previous one. |
|||||
| API Support » GF COM API Prioritize Requests May 26, 2021 @ 09:29 AM (Total replies: 8) | |||||
|
You are right, in some cases, the subsequent request is waiting for the processing of the previous ones. Loading contracts is just such a case. We do not currently support a prioritization mechanism for requests. But we will consider the possibility of improving our system. Regards, Sergey. |

| API Support » GF COM API Prioritize Requests May 24, 2021 @ 05:02 AM (Total replies: 8) | |||||

There is no direct connection between when you sent a request and when you received a response. Our servers process your requests and return the result as soon as they are ready. For example, there is no direct relationship between the processing speed of requests for contracts and orders. So, “Is there a way I can send something through the api to prioritize my order request over my contract load requests? Hope this makes sense.” It doesn't make sense. Regards, Sergey |

Probably your issue here is that you are trying to call Connect from the Disconnected event handler. You need to wait for the current process to complete. For example, in “GF API COM C++ Sample” I did it like this: void __stdcall CCppCOMSampleDlg::OnDisconnected(GF_Api_COM::DisconnectionReason reason, BSTR message) { std::thread::id this_id = std::this_thread::get_id(); CString string(message); log << "Disconnected due to " << string < //----Emulating the repeated click of the button by the user HWND btnConnetHandle = GetDlgItem(IDC_CONNECT)-> GetSafeHwnd(); ::PostMessage(btnConnetHandle, BM_CLICK, 0, 0); } |

“I see no way to otherwise distinguish real from fake.” See GF.Api.Orders.IOrder IOrder ParentOrder { get; } IReadOnlyList SubOrders { get; } or GF.Api.COM.Orders.IOrder IOrder ParentOrder { get; } IOrderList SubOrders { get; } “ So I guess my remaining question is: why are these fake orders coming through the API at all? What possible use could I on the client end have for them?” You can work with both parent orders and sub-orders. I.e. If you modify\cancel the parent order => sub orders will be modified\canceled corresponding way If you modify\cancel sub orders => the parent order will be modified\canceled corresponding way |
