In this tutorial you will learn how to obtain current price for a chosen symbol in real time. The code will be written in C#, but it is not complicated and could be easily rewritten to any other language.

The whole code used in this tutorial is available here:


Commands used in this tutorial:

  • getSymbol,
  • getTickPrices(streaming)

Before you start...

  • To complete this tutorial, you need C# wrapper (available here: developers.xstore.pro/api/wrappers) or be able to use all commands listed above by yourself,
  • We assume that you have at least basic knowledge of xAPI and you are able to establish a connection and login to the server.

Step 1. Init streaming

  1. Create new connection and log in to the chosen server using your credentials.
  2. Establish a streaming connection.
  3. Subscribe to tick prices for chosen symbol, in our case it will be EURUSD.
  4. // Connect to server
    SyncAPIConnector connector = new SyncAPIConnector(serverData);
    Console.WriteLine("Connected to the server");
    // Login to server
    Credentials credentials = new Credentials(userId, password, "", "YOUR APP NAME");
    LoginResponse loginResponse = APICommandFactory.ExecuteLoginCommand(connector, credentials, true);

Step 2. Create callback function

  1. Create a callback function with single parameter of type StreamingTickRecord.
  2. static void Streaming_TickRecordReceived(StreamingTickRecord tickRecord)
        if (tickRecord.Level == 0)
            Console.WriteLine("Current price: " + tickRecord.Ask);

    IMPORTANT! If you want to display a single price for the user you should use only the tick records with the level value equal to 0. That is why the line if (tickRecord.Level == 0) should not be omitted.

  3. Subscribe to the TickRecordReceived event using the callback function.
  4. connector.Streaming.TickRecordReceived += Streaming_TickRecordReceived;

Step 3. Get initial symbol price

  1. Use GetSymbol command to get initial symbol price.
// Get current price
SymbolResponse symbolResponse = APICommandFactory.ExecuteSymbolCommand(connector, "EURUSD");
Console.WriteLine("Initial symbol price: " + symbolResponse.Symbol.Ask);

Step 4. Run the code!

  1. Run the program. After a while you should see similar output:
