  • Can you add more details to your question? What do you want to know that would not be satisfied by clicking through the first five or ten links of the obvious Google search on the topic? – nvoigt Oct 26 '16 at 05:08

Server API is tend to be used to write server plugins, which will be loaded into server memory at runtime. You can use .NET code there, however it's not the best idea.

There is Manager API, I think, it's functionality is sufficient for web application. However officially it has only C++ API. But you can use my wrapper to access it from ASP.NET: https://github.com/Uriil/MetaTrader4.Manager.Wrapper

But both options requires manager credentials

  • Thanks Urill, So using your wrapper should i create new account on MT4 server.So my all concern is to connect with MT4 with manager credential and then add new user to MT4. – Mohsin Ali Oct 26 '16 at 07:21
  • Yep, it won't be a problem – Uriil Oct 26 '16 at 07:23
  • Can you expose any method or Interface for User Registration which i invoke in c# and pass value to c++ method.Please any link or guide line. – Mohsin Ali Oct 26 '16 at 08:09
  • @MohsinAli method UserRecordNew – Uriil Oct 26 '16 at 08:16
  • ClrWrapper took login as integer but i have string value provided by my client. Here is your example Login = 123456.What should i do now.Sorry – Mohsin Ali Oct 26 '16 at 09:49
  • Internally login is integer, and if you have string, it means your client have some custom authentication and you need to discuss it with him – Uriil Oct 26 '16 at 09:51
  • Sure i'm going to discuss with him. Thanks – Mohsin Ali Oct 26 '16 at 10:00
  • I get new credentials and added a user using UserRecordNew and it returned me 1.so my client told me it should be 4,5 digits like 1234.In my case it returned 1 so what it does means. – Mohsin Ali Oct 26 '16 at 10:27
  • Result is status of operation. Newly created login will be assigned to Login property of passed UserRecord object. Mandatory parameters: Name, Group, Password, InvestorPassword, Leverage – Uriil Oct 26 '16 at 11:04

  • great, any guide or explicit steps about adding these package to my solution.Thanks – Mohsin Ali Oct 28 '16 at 05:11
  • U have to install it from Microsoft web site – Uriil Oct 28 '16 at 05:12
  • i already have these on my machine but for hosting server do i need to copy these from Microsoft web site and add it to my solution.Its little bit confusing for me that's why i asked you.Any how thanks i'm googling now – Mohsin Ali Oct 28 '16 at 05:16
  • U need to install them on host server, not copy – Uriil Oct 28 '16 at 05:26
  • My client has Hostgator hosting.Is there a ways of installing binaries or packages directly on any hosting site. – Mohsin Ali Oct 28 '16 at 09:31
  • I guess it depends on provider and you have to talk with your server administrator. I always using dedicated server, so it's not an issue in my case – Uriil Oct 28 '16 at 09:40
  • Uriil i got reply You wont be able to us c++ on a shared windows plan.You will have to get a dedicated server to get that installed.So Is there any other way? – Mohsin Ali Oct 29 '16 at 08:02
  • You will have to investigate it on your own. However I would consider switching to dedicated server, since prices for them are low – Uriil Oct 29 '16 at 11:27
  • Uriil i want to get user history on MT4 by its MT4 id.Is there any method which return me a collection.i am looking for fields type,balance,equity. – Mohsin Ali Dec 10 '16 at 07:42

  • To change balance, u need to use TradeTransaction. But I suggest u to read documentation for mtmanapi on support.metaquotes.com – Uriil Dec 17 '16 at 11:41
  • TradeTransaction accepts TradeTransInfo instance and it has no field with balance.Actually i need a method which update the UserRecord class field Balance.UserRecordUpdate take UserRecord instance but it doesn't update the Balance field. – Mohsin Ali Dec 17 '16 at 16:35

  • Complete example //Deposit / Withdraw (assumes login: the account of the user, amount how much to deposit) TradeTransInfo info={0}; info.type =TT_BR_BALANCE; info.cmd =OP_BALANCE; info.orderby=login; info.price=amount; //negative for withdrawal strcpy_s(info.comment, "No comment"); int res=ExtManager->TradeTransaction(&info); if (res != RET_OK){ MessageBox("Could not deposit"); – Mohsin Ali Dec 19 '16 at 17:04
  • i tried with only price field.here is my code.var info = new TradeTransInfo(); info.OrderBy = 123456; //Login value //info.Cmd = OP_BALANCE; info.Price = -model.LiveUserWithdrawFund.Amount; var i= metatrader.TradeTransaction(info); – Mohsin Ali Dec 19 '16 at 17:07
  • I want to update Balance values as user want to withdraw his money.I also read the doc but i'm failed to understand. https://support.metaquotes.net/en/forum/3349 – Mohsin Ali Dec 19 '16 at 17:11
  • i got the values. var info = new TradeTransInfo(); info.OrderBy = 123456; info.Cmd = TradeCommand.Balance; info.Price =- model.LiveUserWithdrawFund.Amount; var i= metatrader.TradeTransaction(info); – Mohsin Ali Dec 19 '16 at 17:25
  • U missing type property – Uriil Dec 19 '16 at 17:45
