Good morning, I restarted the old project without updates and only updated the GFAPI.4.11.519.358 package. Now everything works. Thank you. |

I used the latest version of the AdvancedExample and updated the GFAPI references to the latest version. I'm having this problem with both the C# example and my VB.net executable that worked before the update. |

I have updated the package "GFAPI 4.11.519.358" and now I am getting this error on this command "GF.Api.Impl.GFApi.CreateClient()": "System.TypeLoadException: 'Il metodo 'TryGetConstructor' del tipo 'GF.SimpleInjector.InternalConstructorResolutionBehavior' dell'assembly 'GF.SimpleInjector, Version=4.11.519.358, Culture=neutral, PublicKeyToken=b6b45f27e2749b17' non ha un'implementazione.'". I also have the same error with the advanced example. What am I doing wrong? Thank you." |

TK. With the API of a Block Account, is it possible to have the total position? I have the position of the individual accounts, but the total one, as if it were a single account, gives me back 0. I solved it by cycling the sub-accounts, but if it were possible to have it directly it would be better. Thanks and sorry if I take advantage. I write you the code that I use now Dim GL_Account_AB As IAccount = gfClient.Accounts.Wash.Get.First Dim GL_Account_ As IAccount = gfClient.Accounts.Get().First Dim account As Accounts.IAccount = Nothing Dim totalBalance As Balances.IBalance = Nothing If GL_Account_AB Is GL_Account_ Then Dim Disp_ As Double = 0 Dim Liq_ As Double = 0 For Each Account_ In gfClient.Accounts.Get totalBalance = Account_.TotalBalance Disp_ += totalBalance.NetLiq - totalBalance.PortfolioMargin.RiskValue Liq_ += totalBalance.PortfolioMargin.MaintenanceReq Next Lbl_Disponibilita.Text = FormatNumber(Disp_, 0) Lbl_LiquiditaVinc.Text = FormatNumber(Liq_, 0) Else totalBalance = GL_Account_.TotalBalance Lbl_Disponibilita.Text = FormatNumber(totalBalance.NetLiq - totalBalance.PortfolioMargin.RiskValue, 0) Lbl_LiquiditaVinc.Text = FormatNumber(totalBalance.PortfolioMargin.MaintenanceReq, 0) End If Edited by FGiordano538 on Sep 15, 2022 09:46 AM Edited by FGiordano538 on Sep 15, 2022 12:21 PM Edited by FGiordano538 on Sep 27, 2022 03:41 AM |

I have installed the new version, but it returns this error. In the link I have also inserted the image of the installed packages. https://imgur.com/a/YVS4Hjn Then I updated the versions of all the packages, and it gives me a different error. I'll post the error and packages with versions.https://imgur.com/a/ihAklZW What am I doing wrong? Thank you. |

Hello, I need to place a complex, synthetic order with three titles (legs), on the platform I use the "Custom" type Code 88, but among the various types of orders with the API the codes range from 0 to 87. It is Is it possible to create a complex order of the Custom Code 88 type through the API? |

Thanks for the reply J.Smith. If I want to place an order with 3 legs (BUY 1 OESM23 P3000, SELL 1 OESM23 P2800, SELL 1 OESH23 P2700) what can I do? What type of "CompoundType" should I use? Edited by FGiordano538 on Sep 08, 2022 04:23 AM |

I solved, with "Client.Contracts.Lookup.BySymbol (Symbol)", scrolling through a list and I request the data of the title individually and then I subscribe it. Same thing to unsubscribe. So I don't have the 50 limit of the "client.Contracts.Lookup.ByCriteria" command |

with the command "client.Contracts.Lookup.ByCriteria", I can download symbols with a common base, maximum 50. With "Client.Contracts.Lookup.BySymbol (Tit_)" I download as many as I want, but I need to know the exact symbol. it seems to me that with the command "Client.Contracts.Load.Request (Request.Build)", I can download all the options of an underlying in groups of 1000. I tried but failed. Place the code. Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click TitoliRichiesti = gfClient.Contracts.Lookup.BySymbol("ESZ22") End Sub Sub gfClient_SymbolLookupReceived_(c As IGFClient, e As SymbolLookupEventArgs) If e.RequestID = TitoliRichiesti Then For Each contract As GF.Api.Contracts.IContract In e.Contracts ScaricaOp_Sottostante(contract) Next End If End Sub Private Sub ScaricaOp_Sottostante(contract As GF.Api.Contracts.IContract) If contract.HasOptions Then Dim _loadContractExpression As New ContractLoadExpressionBuilder _loadContractExpression.Push(New ParentContractIDCriterion(contract.ID)) _loadContractExpression.Build() Dim Request As New ContractLoadRequestBuilder() Request.WithSkipCount(0) Request.WithResultCount(1000) Request.WithExpression(_loadContractExpression.Build) Request.Build() _loadRequestID = gfClient.Contracts.Load.Request(Request.Build) End If End Sub it returns me this error "System.InvalidOperationException: 'Tree must have single root.
